SQ : Anthem receiver vs. processor


Hi everyone,
I’m on a quest to simplify my life and get rid of my separates. In terms of a range of options, I’m probably settling on Anthem. My choices are:

  • MXR 720 - 7 Channel receiver ($2,500) and use external amps for L and R
  • AVM 60 a pure processor ($3k)
  • Classe SSP used (~ $3k)

I’m wondering if any of you have direct experience comparing the sound quality of each? I have an external DAC I’ll be using for music sources.

The processor total cost of ownership is significantly higher, not to mention space and wiring required.

Not sure if the Sigma Amp5 class D amps would digitize its inputs upon entry. You should email Classe Audio technical support group and find out. Wouldn’t think it converts its inputs to digital. When I first listened to the Classe Sigma SSP + Sigma Amp5 combo at the store we used different source components to listen to music using both high end ARC Reference CD player as a source going analog into the Sigma SSP with the Sigma SSP set in bypass mode and streaming directly via USB input on the Sigma SSP, and they each sounded very different.
My friend who happens to own a hifi store said that he also tried using different HT preamp processors with the Sigma Amp5 class D amp and each sounded different. So it made me think that if the Sigma Amp5 amp converts the input to digital regardless of which preamp and front end components used they would all have sounded the same, right? 

I knew you like class D amps but I would pair the Sigma SSP with Classe Delta series class AB amps or Parasound Halo amps (class A/AB) or any good quality class AB amps if I were you but you said earlier that space is an issue for you and the Classe Delta series class AB amps and the Paradound Halo A21/31/51 are huge and very heavy, and the Classe Delta series class AB amps cost much more than the Sigma class D amps.

However,

Classe calls their amps "digital Class D" which indicates this, plus this from the Amp5 SoundStage review :


This input stage uses a proprietary analog-to-digital (A/D) conversion stage shared by the SSP-800 and CP-800,

So I’m pretty sure. :)

There's nothing wrong with this approach, by the way. It just makes it kind of useless for me to bother with a separate DAC.

The Theta Casanova did this with all analog signals, and it did it very very well.


Best,

Eric, did you see the Krell S1200U up for sale at $2199?   It's not a 3D model, which means that it probably has the HDMI 1.3 board, but it's a great price.

I went to Brooks Berdan in Monrovia. A great store, with the repair center in the middle and opwn to view. Highly recommended!

But they only had one Anthem AV receiver and it was not hooked up.
