I am finalizing my choice for amps for B & W 800ds. I am looking at the Classe CAM 400, the Pass Labs 300.5 and the McIntosh 500 w per channel amps. Any thoughts from any of you who have these as to which are the best? Thanks.
Best Amps for 800Ds

Welcome to the club Dave.
My short answer would be all of the above.
I have auditioned the Pass Labs with TAD loudspeakers and the McIntosh with McIntosh loudspeakers but to date neither with B&W so my feedback on sound quality is limited but either will drive the 800D without any problems.
I use a pair of Classe' CA-M400 to drive my 800D and contrary to some misguided opinions have the guts and the finesse to drive them at very high SPL with no lack in bass output nor any high frequency distortion that I can tell. These remarks are backed with SPL tests I conducted not so long ago using two-channel stereo and multi-channel cinema sources.
In the case of two channel stereo sources, I easily drove my 800D to 107dB (@ -5dB unity gain) continuous output at my seated position, 12 feet away, for 20 minutes straight using heavy percussive soundtracks and neither the 800D nor the CA-M400 flinched in the process (ears were protected).
With respect to multi-channel cinema sources, I piped all LFE and low/sub frequency signals through my CA-M400s and 800D which gave new meaning to the phrase aftershock. My house was more at risk to the shattering explosive power that came through my system than the system itself ever was.
Anyone who thinks the CA-M400 is intimidated of prodigious low octave output and/or squelshes treble in the process does not really know the CA-M400.Last edited by RebelMan; 03 April 2007, 14:18 Tuesday."Dream as if you'll live forever. Live as if you'll die today."- Bottom

B&W used the Classe amps, and likely the CA-M400s in the design and voicing of the D series. So they ought to sound the way B&W intended them to sound with those amps. Obviously, not everyone has the same musical taste, and might prefer some other amp. But I would at least give the Classe a try.- Bottom

I drive my 800D's with McIntosh but I use the 1201's (1200 watt) and use the 4 Ohm tap.As told before I would have chosen Classé as second choice, it's only a matter of looks and taste, because those CAM-400 blocks are as good as McIntosh to drive those speakers.
I would say welcome to the 800D club :T- Bottom

2 cents.
I have and happy with the X250.5 driving the 802D's. Nice sound combo.
I have ordered the MC501's, not so much because ~I didn't like the sound which I think is great, I just don't like the look of the Pass Labs compared to the McIntosh look.
I have a friend who drives his 800D's with 1201's and 501's and says he likes it better than the Krell 400CX he was using before.
so Pass Labs are great sounding with B&W
But as anyone will tell you in this forum, its not about what is better, because All the Amps you are talking about are great, its a matter of your personal taste.
Which sound do you prefer. (considering as well the other components & accessories work well with 800D's and Brand X Amp)- Bottom

I have 800Ds and went from Classe CAM/350s to Lamm 1.2 Refs which are only 110 Watts... I will tell you the Lamm beats the Classe hands down.
Thanks for the catch... Long day!- Bottom

These are my two cents and I added krells into the picture:
Classe: airy, controlled bass, less detailed, very easy on the ears, very fast transitors (galloping horse)
Mcintosh: similar to classe, very fluid (great for classical, instrumental)
Pass lab: great mid-high, bass is less powerful
Krell (what i use): extremely powerful bass, weaker in the mid range, very bright and detailed = may cause fatigue for some people (great for pop/jazz/r&B/metal) - raging bull
Different people prefer different sound and all the amps that are mentioned above are top notch. My suggestion is do some research on these amps and see what are each strengths and weaknesses before auditioning the amps. When you auditon these amps, you are already fully prepared to know what to listen for from your research; your ears would show you the light!
Good luck!

But a few years ago, I was comparing a few integrated amps...a Krell, a Classe, and a Musical Fidelity. The Krell had more authority on the low end and was very dark and detailed through the midrange and the high end was just there....not too airy...not too dull...it wasn't exactly fatiguing....but it was a bit more present. The Classe had a liquid smooth top end and a very accurate and crisp midrange and the low end was articulate and very smooth sounding...and it had impact, but just not quite with the presence of the Krell.
The MF seemed to be somewhere in between the Classe and the Krell...I liked it...but the more I listened (over a few weeks/months) with different music, I really preferred the Classe overall.
Either way, you wont be disappointed.- Bottom

Don't mean to distract too far from the topic, but isn't the characteristics described by these amps more or less a function of the Pre-Amp/Processor?
If i used a mediocre Pre-amp as the front-end to say a Classe amp, would i still see the benefits of airy, controlled bass, less detailed, etc compared to say a Krell attached to the same Pre-amp?- Bottom

Next to room acoustics and loudspeakers, the pre/pro predominately owns the audio signal. In theory the purpose of the pre/pro is primarily to serve as the central hub where all signals enter and leave without influence, in other words it should be a completely neutral place for signals to pass. In practice this is hardly the case. Many if not most audiophile grade pre/pro’s are deliberately colored to sound natural and pleasing according to the manufacturer’s interpretation of the terms.
The ideal amplifier, essentially a straight wire with gain, will also stay out of the way as it amplifies the signal. Again this is not usually the case but the vast majority of audiophile grade amplifiers are closer to neutral than their corresponding pre/pro counterparts are and for deliberate reasons. But any deviations from the norm are usually executed (voiced) in support of the front end piece upstream and it is for this (sound quality) reason why pre/pro’s and amps be brand matched where ever possible."Dream as if you'll live forever.

If you have no money issue go for a Plinius SA-Ref, it's the best I've evear heard on BW (801D).
I won't recommend you Classe because I don't like the sound these amp produce with BW, tried several times, but definitively not for my ears.- Bottom

Very unlikely. Any mediocre component upstream will mask the full potential of a quality amplifier. Looking at it another way, a quality amplifier will reveal the inadequacies of the piece in front of it.

Glen B; Just to clarify... I wasn't trying to compare AMPS based on price in my post. Many were talking about more power and I was making the comment that 110W Lamm sounded much better than 350W Classe Cams so to illustrate that power isn't always the thing to look at even with 800D B&Ws.- Bottom

I'd go with the VAC Phi gear.
Integrated 7.1 HT and Two-Channel System
Pioneer KRP-600M | VAC Phi Beta 110i | to be determined front end
B&W 802D | B&W HTM1D | B&W ASW-825 | B&W N805 | B&W SCM1
VPI Scout | Oppo BDP-95 | Tivo Series 3 | Integra DTC-9.8
Audio Refinement Multi-5 | PS Audio Premier | Goertz and Electra Glide cables- Bottom

Lamm 1.2
Rebelman;
I changed to a Meridian 808 CD player a couple months ago as well as an ARC REF3 preamp (upgraded from Levinson 320s)... I had this setup with the CAM/350s for several weeks prior to upgrading to the LAMM 1.2s.- Bottom

Which Krell amp are you using? I am thinking about the Evo 403 but it has been suggested to me that it isn't powerful enough (hard to believe).
Any thoughts?

I have the 750 MCX, the older model with 800D's. Monoblocks are the best to control and drive the speakers compare to stereo amps or multi-channels but it is hard to believe any krell amp's isn't powerful enough especially a whooping 400 watts from the Evo 403. I believe power shouldn't be the issue if you have B&W speakers because B&W speakers are relatively easy to drive. What kind of speakers do you have? I dont' have any experiences with the new EVO lines and with the amount on the line, I think the best way is for you to go to a dealer and test it out. I heard the EVO line has better mid range and treble than the older versions (but still not as smooth as Mac's and Classe) and in the same time tamed the brightness. Good luck and let us know!- Bottom

This is the result of my audition between Krell 750mcx and Classe Delta M400 one and a half years ago. Krell will be on the left and Classe on the right:
Music Bright - Music Softer/Soothing
Music Define/Detailed/Crisp/Colder - Music Warm/Airy
Bass Extremely Powerful/Unbelievable - Bass Strong/Crisp
Mid Range ok - Mid Range Airy
Music Tailored to Rock/Hip Hop/R&B - Music for Classical, Jazz, Vocal
I guess it would depends on your taste to choose what amp for your speakers. Both are wonderful amps so it comes down to a matter of taste. Good luck and share with us what you decided on!!!

they will add hdmi to the next gen ssp's. They have decided not to add a scaler, as they feel it is redundant, since a lot of displays are coming out with good scalers built in.I'm just sittin here watchin the wheels go round and round...- Bottom
