I know there is an extra analog to digital to analog conversion with the Catalyst speakers due to the DSP. I was wondering if this degrades the sound quality or signal sent from the pre/pro? If I get something like an RS20i or Altitude32, will the sound quality of their excellent DACs be worsened because of this?

IMO, many get way too caught up with the idea of another AD-DA conversion.  The only real concern is noise floor which can increase during the A-D processes.  The analog stages on either end of the AD-DA are more likely to have an impact on sound than the actual process.

In the case of an active speaker like the Catalyst, the speaker is designed with the entire chain from the XLR input to the drivers as a whole.  Most grossly underestimate how significant a broad, +/-0.5dB tilt at the higher frequencies is to the "detail" perceived. 

Much more important than the question of if the A-D conversion at the input of a Catalyst reduces something is the question of how much improvement does the DSP executed crossover through 3 discrete amplifiers offer vs a passive execution.  Is that benefit greater than having to make the design work with passive components?

Hello! I'm planning on buying 3 catalyst 8c for my front channels in my hometheater. I'm considering the marantz 7702 Mkii as a pre/pro. Is this a good choice for these speakers? Which pre/pro are others using with their cat 8c's?? Any help will be appreciated.

I would include the Anthem AVM60 in the list of considerations.  Many have been very happy with the 7702 & 8802a and they are one of the few options along with the new AVM60 to include competent room correction.  If you're looking at external room correction like Dirac I would add the Yamaha's 5100 to the list, but the 7702 is one of the best values you will likely find that includes Atmos and DTS-X.

Mark,
I am planning to audition both the 7702 and Yamaha 5100 to see which one I prefer better.  You recommended the Yamaha 5100 if you get Dirac.  I noticed in your demo room at Axpona, you used the Yamaha 5100 with Dirac.  Are there negatives on the Yamaha 5100 YPAO compared to 7702 audyssey that I should be aware of?

Any issue using a receiver with the catalysts?

As long as you are able to take the output off ahead of the amplifier section (Like a pre/pro)

So any one with rca pre-outs would suffice?

I thinking of changing things up and going catalyst 8c l/c/r; trying to figure out if my anthem MRX 710 would do (and hence power the surrounds of its amp section)

As an aside - regular 15amp circuit woujd work fine?

I am powering my three Cat12Cs and my two SubMs with a 40Amp 240VAC circuit.
