Rotel RB-1070 or Rotel RB-1080 combination

[specialized]

Hi there.. Im driving my 803S with Rotel RB-1080 per speaker (biamped).

The sound that they produce is very nice..

Also i have HTm3S and 805S. HTM3S is driven by one Channel of Third RB-1080 that i have, and second channel of RB-1080 drive one of 805S. The Second 805S is driven by Denon 3808 receiver i have.

Question: Im thinking to buy RB-1070 amp. If i done that, what would be better situation:

1. RB-1070 to drive 805S, and RB-1080 to bi biamped to HTM3S.

2. RB-1080 to drive 805S and RB-1070 to bi biamped to HTM3S

I'd say, biamp the center with the RB-1080, since it is the larger centerspeaker, it is in a sence a 804 in center (D'Appolito) configuration. The 805's can then be driven using the RB-1070. Since dialogue channel is very important and needs to be matched to the fronts, powering them the same way will help in the integration. Effects channels like the side and rears are 'less' important for movie playback.
If you're also going to play multichannel music (SA-CD or DVD-A multichannel) then the rears are also important and need to be 'voice matched' to front and center speakers.....

I agree with BWzes03. That would be the way to do it.

I also vote for option 1. The amplification across the front three will be the same, improving system synergy.

Yes.. Im also interested for SA-CD and DVA-A. Since 805S is different type speaker then HTM3s and 803s, does that mean it's not a good combination for my fronts?

Hallo,

strange I had used the RB1080 for the 805s and the RB1070 (and not bi.amp) to drive the htm3s!! :x


I have always my center with a paar db minus vs. the mains speaker.
I like so.

That depends, I'm unfamiliar with the 'timbre' of the 805's. The 'issue' is that multichannel music in SA-CD and DVD-A are 'counting' on all speakers to be the same, and full range. Meaning that the rear channels will also contain signals in the lower registers. Older models of universal players were unable to do bass-management on SA-CD and DVD-A playback, causing the rear speakers to deal with signals they cannot reproduce.
Also, the overal sound 'color' from the speakers need to match otherwise a guitar (or any other instrument) being 'panned' from the front speakers to the rears will sound completely different.

I wanted a 804s, but they were not more produced So dealer have a 805s and i thought that still it's 800 series, and it would be matched to the front end

Like I said, I'm unfamiliar with the sound color of the 805's compared to the 803's just try to play stereo with one 803 and one 805 in the front to see if the overall sound color matches. if it does, you will be able to play mutichannel music without any 'sound color' problems...

I installed RB-1070 on 805s. I also biamped 1080 on HTM3S. It sound amazing now. Also i found out that sub that i have destroy the quaility of sound and it's much better without Sub (Mordaunt Short Avant 309i). Seem that i cant adjust it properly or it's not match with the rest of the speakers. I'll try few more days but more is that i'll sell it and go without sub one period.
