Jimmy,
I'll be interested in your findings. I did a direct "head to head" of the Ref 8 against a Bel Canto Evo 2 and for my ears (and the others) once we got used to the amzing difference in sound - the extra detail and control of the Nuforce was was hard to believe... And I know the Bel Canot really well and love it!
I'm off to hear the new Ref 9 this weekend...

Your link is broken. Is this the correct review? I looked at the site and from the comments, I'm assuming you are talking about the Reference 8?
Ref 8
Sounds really interesting. No, digital amps aren't snake oil. They are just one of the new technologies being rolled out in electronics. Those shots of the internals look really weird without a big transformer sitting there. Geoff, keep us posted on your review of the Reference 9, okay?.

Jimmy - can't wait to hear the comparisons to your Bryston, Krell and other top notch amps you carry.
By the way, the owner/manufacturer of Nu Force has his own "circle" which has overrun the overall Forum that its on with its posts and new threads. EMAIL ME if anyone is interested in knowing the website.Adz- Bottom

Can you check out the RRP of both the Ref 8 & 9 in OZ?
Looking forward to hearing your comments on the Ref 9 and how it sounds against the Halcro MC20. I am after something to power my mains, as I have ordered the Elektra Theatre 7 for my centre & surrounds.
I see Perreaux have a new range also.Richard

Spearmint,
I'm not sure if is RRP or a discount but the Aussie $ quote I got from the distributor WAR Audio was:
> Ref 8 $2250 a pair
> Ref8B $2500 a pair
> Ref 9 $3300 a pair
I'll let you know how my listening goes...

The Ref 9's look like they might be in my sights, will give WAR a ring monday to find resellers in Victoria.
Looking forward to your comments on the amps...Richard

Spearmint,
Re the sound.... They are very good. The Ref 9s are tonally very similar to the Ref 8 but punchier with that "big amp" sound. Hard to compare as WAR only had the (also excellent) Bel Cantos to compare. However interestingly in the time I was there two others turned up. One to rave about beta 70W Bel Canto and how well it drove his speakers. He had brought in a pair of older model Stax Headphones and insisted everyone head how well the NuForce drove them. He had all sorts of amps at home, including Krell and raved over the Nuforce - just wanted a little more power than the 70W ones as they (surprise!!!) clipped on one channel when driving his Apogee speakers... He said the amp brought out qualities in his speakers (he had 4 pairs) he didn't know they were capable of...
Then another to return the Ref 8s he had taken home for a demo - similar rave reviews....
The sound is distinctive - very much like (I know I know) Single Ended Valve Amplifiers and (a little) like the classic Krell Class A amps. A sweet, neutrral and very detailed sound that is so fast, transients (bass mid and treble) are just instant, with the speakers always seeming under control.
So some more listening is in order I think!

When will you get a chance to listen more? Do you think that they would do a proper job running N803's in 2 channel or a full surround setup of B&W speakers?

Wow thanks Geoff…
I sent WAR an email yesterday, and they responded very quickly, the Ref 9's are due in the end of the month and have a pre order special going which includes delivery to your door.
Currently I am tossing up between a pair of Ref 9's, the Halcro MC20, and Elektra 2ch Reference, for my 2ch duties.Richard

We have just received the go-ahead from NuForce....we are officially authorized dealers!
As I mentioned a little earlier, I have 3 Ref. 9's on the way to demo in my showrooms. We are going to demo them on some VMPS RM40's, VMPS LRC, VMPS RM30's, Dynaudio Contour S 5.4's and SCX center within a week of receiving them. We'll report our findings.
I am privileged to carry the products I have. I take it as an honor when a distributor or manufacturer gives us the green light to come on board. This product and company is truly special though because of the potential of the products they are producing.

I think it would sound spectacular. I am trying to borrow some Ref 9s to try them on 802s but I don't know if I will succeed...

I posted this in the HT Forum as well but thought it was fitting for here as well:
Hi Guys,
I spent all day today comparing several amps, preamps and speakers with another 15 guys here in Fort Worth. Needless to say, one of the highly anticipated items we thoroughly reviewed was the NuForce Ref 9's that just came in. The pair was directly compared to several different amps and we controlled the amps with several different line stages. We used the Cary Audio SLP-98P Preamp, Dodd Audio Reference Preamp, Resolution Audio Opus 21 CD (with and without variable output), Cary Audio 303/300 CD (with and without variable output, both tube buffered and solid state outputs) along with several nice speaker selections including the Anthony Gallo Ref3's, Salk Sound Veracity HT1, Dunlavy SC-IV/A and several others. Top notch power conditioning and cables were used throughout. The amps we swapped in and out included the NuForce Ref 9's ("Digital Amp", $2,400 MSRP pair), Halcro Logic MC20 (2 Channel Digital Amp, $4,490 MSRP), Cary Audio CAD 500 MB ($6,000 MSRP pair), PS Audio GCA-250 (2 Channel Digital Amp, $2,995 MSRP), Parasound Halo JC1's ($7,000 MSRP pair), Dodd Audio 120 Watt Tube Mono Blocks ($5,200 MSRP pair).
After several hours of testing, there were definitely LOTS of opinions among the group of veteran audiophiles as to what was preferred. One consistency was that everyone kept coming back to the Gallo Ref 3's with amazement as to how such a relatively small speaker sounds so surprisingly big. It was definitely a winner for the day. The other big surprise for me was how awesome the Dodd Audio gear was. What an incredibly rich sound. The preamp is near flawless. Now the bad news, the glaring consistency within the group was how disappointed everyone was with the NuForce Ref 9s (no exaggeration - 100% of the attendees.) The Ref 9s just didn't live up to all their hype. I personally thought they created a very narrow sound stage and showed little to no life. I rarely say this about any brand, much less one for which I had high expectations. I really think they need to go back to the drawing board. This result was not consistent with the other "digital" amps. The Halcro and PS Audio units were awesome and really held their own against the big monoblocks. They had differences in sound in comparison to the monoblocks, but still a completely full soundstage with rich, extended bass (something the Ref 9s lacked.)
Sorry to disappoint as I know some of you have high expectations as I had, but figured you guys would want to know.
Feel free to ask questions while I have a fresh memory of the gear.
thanks,

The JC1's were very well received by everyone. These guys are hard to beat, but they are above some people's budget. The have a fairly large sweet spot and extremely solid bass with well supporting mids and expressive highs. Very open, yet authoritative. The Halcro MC20 was the big surprise in my comparison. Halcro really set out to duplicate their signature sound found in the reference D68/D58/D38 ($20 to $60K) amps and they did just that. Excellent performance and definitely the absolute best digital amp I've ever heard and that list is fairly long now including Bel Canto and Spectron. The sound stage was full, the sweet spot was wide and the low end was very clean and accurate. I can also say that it doesn't stop with just outperforming other digital amps either. It was in the same league as the Cary and Parasound Monoblocks as well as the phenomenal Dodd Audio Tube's. At $4,495 MSRP, it's not cheap. At a good street price it will be extremely competitive and should be on anyone's short list. They have identical 2, 3, 5 and 7 channel chassis units so home theater and 2 channel can easily be accommodated. Everyone was highly impressed with the MC20...another winner for the day.

Which specific components were in the chain when you listened to the Reference 9s? How much burn-in time had they gone through? Also, could you elaborate a bit more on detail, dynamics, etc. I'd like to get an idea of what specifically you didn't like so I can make a note when I listen to them this coming week.
BTW, they are not digital amps.
Thanks.

NuForce only ship out production Ref 9 by FedEx ground in the US to dealers starting from August 25 and 26 (and it takes 3 days to get there). We did send a pair of pre-production Ref 9 to a Texas audiojam.
So how is it possible to breakin the amp by Sunday assuming someone even receive it on Friday? Ref 9 recommened breakin time is 75 hours.
NuForce amp has zero phase shift so unlike other amps, you should NOT toe-in the speaker as much as with other amps. That will affect the sound stage if you toe-in the speaker.
I would be very careful of such a biased comment.

Well, I decided to follow up with one of the attendees since I was intrigued by Brent's thoughts. The amps used at the audio jam were pre-production Reference 9s. Jason from Nuforce has been swamped with demand and these units were the only ones he had available. The pre-prod units had a non-standard case and less capacitance than the final production versions. Additionally, the new power cord that is shipped with production models was unavailable so the group used another one (not sure what kind). I inquired about the number of hours on the unit and was told burn-in was limited mostly to in-house Nuforce testing.
So, to each their own. Since I'm not a big tube amp guy, I'm still eager to hear these babies. Especially given their price point!

Originally posted by K~JDid these units go through burn-in time? Also, when you say little to no life are you referring to warmth? These are supposed to be incredibly detailed with quick dynamics by all other reports.
When I say little to no life, I was referring to the overall sound stage. It was not open and realistic. It sounded like a veil was placed over the music. Don't get me wrong...it wasn't as if they sounded like total crap...they just didn't do it for me.

Biased comments are kind of funny. If anyone is going to have one it's going to be someone that works for the manufacturer. Yeah, I'm a dealer for about 120 lines of A/V but I had all intentions to review the Ref 9's and to become a dealer for them as well so where's my bias? I know you don't like what I had to say, but it's just an unbiased opinion.

Maybe I'll still consider them if there is/was a huge difference in the ones I listened to and production units.

No manufacturer from Nuforce was present, so I'm not sure what that is supposed to mean.
As far as I know, these units had ample burn-in (something around 500 hours was stated) from the factory.
We listened to the Nuforce under about 10 different setups. Both tube and solid state. Pretty much everything that I listed was put into the chain one way or another.

It seems kind of silly they would send out bad sounding amps though knowing how they were going to be used.
It was a very high end power cord (a couple different ones if I'm not mistaken.)

We have to limit cable talk do to the forum rules...
If 500 hours isn't enough...how many hours do these guys need?

I promised to loan something to someone (Lee Weilan) who posted on Audiocircle about the Texas audio jam but since we have nothing available to ship (still none will be available until end of Septemper as everythinig is sold out) and I don't want to disappoint Lee, I sent him a prototype amp to check it out. Each amp required 75 hrs of breakin time. The the prototype units were built for various QA and listening test but since we keep swapping them around and changing stuff, I have no idea how many hours of breakin was with the units that were sent.
I NEVER mentioned that it will take 500 hours to breakin (where did that come from?).
6moons, stereotimes, soundstageav reviewers have spent hundreds of hours carefully evaluating NuForce Ref 8 (Ref 9 uses the same circuit board as Ref 8 ) and you can read their comments.
Everyone is entitle to their opinion. But when you posted something about a review, I would expect you to check with the person who is handling the Ref 9 prototype to present some facts along with your reviews.
I also checked with Lee that he doesn't know most of the people that.
You are the dealer of Gallo and Halcro (and you are very familiar with the amps and their setup but not NuForce).
I also learned that the listening room is very noisy and there were people talking. Is the a right way to evaluate an amplifier that you're not familiar with in such an environment and then compared it with other equipments that you're very familiar with?
An unbiased review is one that include some facts about the amp, the conditions in which amp is being evaluated etc.

Before this degenerates into something unpleasant, let me remind everyone that spirited and informative discussion is encouraged here, disagreements are a natural result of the discussion of peoples' opinions and are quite normal. However, sniping and cutting comments are NOT allowed and will not be tolerated. Play nice in the sandbox people.

My personal opinion on this is that once non-prototype Ref 9s are available for shoot-outs or head-to-head comparisions then the results will be of more interest to me.
Being pragmatic about the whole thing, if you look at the Brent's original post of the shoot-out you'll notice that the Ref 9s were up against competition that in all but one case was almost (or more than) double the price. That put them up against some pretty serious amplification, so is it that surprising that in direct listening they didn't perform quite as well as the competition?
FWIW, a pair of the Halo JC-1s are on my very short list of amps to consider when I upgrade, so anything that is directly compared to them will be worthy of note (to me)..

If Brent is responsible for setting up the system and wanted to post a review, then he should at least verify some facts with Lee (as a dealer of Halcro etc, he is obviously very familiar with the amps that he brought there!). I don't care to dispute Brent's opinion (or his supposely summary of everyone's opinions). I already pointed out some other different reviews and let readers form their own opinion.
Ref 9s were up against competition that in all but one case was almost (or more than) double the price. That put them up against some pretty serious amplification, so is it that surprising that in direct listening they didn't perform quite as well as the competition?
It is well known that the high end audio market is shrinking rapidly and just about every dealers have moved into home theater market. It is inevitable that the convergence of media devices and proliferation of digital music formats will create a new generation of audiophiles not willing to pay the high price of traditional linear, solid state or tube amp. We priced our amp to reflect what we see as a trend, not to break new grounds here . Selling high end audio is a high touch service. And we don't have a clear solution of where the right price should be. But judging from the response to our sales and the multiple amps that our dealers are able to sell per customer, I believe this is a doable win-win situation. Consumers get more bang for their bucks (bi-amping, tri-amping, surround sound using monoblocks) and dealers get to maintain the same revenue per customer. What I do know is that if we don't keep offering better values at good price to newer generation of audiophiles, in 10 years time we'll all be selling PC or game based system that has some audiophile grade ICs.- Bottom

Let me amplify on my "price premise" comment (the audience groans ). At a a price of $X for an amp, generally you get a level of internal components I'll call X. If you spend $2X, you enable the manufacturer to spend 2X on the various parts making up the amp. Whether the mfgr really spends 2X on the pieces is open for debate, however I'm willing to walk out on a limb and say that the majority of them being people of integrity will handily improve the internals with that much more of an operating capital window - if not quite doubling their cost. We - as end-users - can generally (indirectly) discern this happening by improvements in the sonic quality the amp at that 2X price is producing. Whether that 2X price is affordable to the buyer is a moot point in this example. Oh, by improvements let's just say that I'm talking about things like lower noise floors, better channel separation, better sound-staging, etc. I don't want to get into a "clinical vs. euphonic" debate. Please, please. . . .

I've pretty much written this off to a bad set of amps...I don't want to spread negative comments about a company that may in fact have a good product. I'll be happy to review a production set and properly break them in while correctly setting them up. By the way, if you peruse audio circle in regards to the demo I heard you'll find similar comments as mine. Based on what I heard, while the Ref 9s were playing on the Gallo Ref 3s (speakers that I'm very familiar with), I did not like the sound. It didn't compete with comparably priced amps either from my reference. The sound from a comparably priced Rotel RB-1080, Cary Cinema 2, Halo A21 or Bryston 2B SST all have a preferable sound to me on the Ref 3s and I don’t carry all of those brands. This is where it stands with what I heard. I would love to be corrected by reviewing a pair from final production.
A few comments...
But when you posted something about a review, I would expect you to check with the person who is handling the Ref 9 prototype to present some facts along with your reviews.
You are the dealer of Gallo and Halcro (and you are very familiar with the amps and their setup but not NuForce)

I do strongly recommend that you back off the rhetoric for a minute and re-read some of the earlier posts in this thread on the introduction of the Ref 8 and 9, and also in this one. My own initial comment was
Brent, I agree that I should have sent you a PM before I posted my response. But judging from the look of the prototype Ref 9, it was obvious that it is not a production unit (and I told Lee that it was a prototype). In addition to that, I was told (not by Lee) by someone that it is not true that the opinion was unanimous. So when I read your posting, it appeared to me that you are being bias. Unfortunately message board doesn't allow quick two way conversation or for people to read each other's expression.
How do you expect me to think that you are being fair when your further response continue to include personal attack ? You used the phrase "making yourself look bad".
If you have said in your original posting of the review about how the setup was done and qualified that the Ref 9 was a prototype AND a lot of the people around you were disappointed with it ....then I will be ok with it.
Let me offer an example.
If I posted somewhere that "everyone who visited Brent's showroom said that it is badly setup and ...", how would you response? Would you send me an IM first or do you think your first reaction will be to post a reply complaining that my posting is bias because it should have been obvious to me that the showroom was under renovation etc. Misunderstanding let to further misunderstanding and attack let to further counter attack.- Bottom

It is obvious to all of of who are watching the Jason-Brent NuForce "Texas Jam" debate that you are both only going to agree to disagree. While I appreciate David's attempt as Moderator to mediate this discourse, Brent & Jason, you both continue to be appear to be heading in the same direction, almost trying to be conciliatory, but mostly adversarial to the end.
As David has suggested:My personal opinion on this is that once non-prototype Ref 9s are available for shoot-outs or head-to-head comparisions then the results will be of more interest to me.
Until this occurs, this diatrabe should be taken private as it is not shedding any real light on the production Ref 9's. This puts this entire thread on very slippery snake oil.Stan- Bottom
