Affordable Processor with Fabulous 2 Channel ?


Gang,

I'm using my Mytek Brooklyn DAC as a pre for music and TV. It is fabulous sounding but I really would like to have 5.1 channel surround, and a single remote! 

Is there an affordable processor (used OK) that has at least as good 2 channel performance? Emotiva is right out. I owned one, and it sounded thin as paper. I note that there are a lot of Krell processors for sale at reasonable prices. 

Thoughts?

I wasn’t implying that the more expensive = the better. Of course does not always work that way. For example, the Classe Sigma SSP stereo performance is actually better than the much more expensive Classe SSP 800 according to many people. I know we are talking about two different generation processors here. But I have to admit that the SSP 800 performs better than the Sigma SSP in surrounds for HT use when using HDMI inputs perhaps partly due to all true differential or fully balanced design for all channels on the SSP 800 vs only the front LR channels on the Sigma SSP. Also partly due to better DAC implementation and configurations and power supplies on the SSP 800 maybe. Perhaps the SSP 800 has better DSP?

But when used as an analog stereo preamp thus bypassing DAC, DSP, and other digital processings lots of people said that in fact the Sigma SSP sounded better than the much more expensive SSP 800 when using stereo analog audio inputs (XLR) and both processors are in analog bypass mode. Classe also claimed the same.

So that being said I think the Classe Sigma SSP will be suitable for the OP since he’s looking for a processor that sounds great in two-channel playbacks for music and the used first original version of the Sigma SSP in after market can be had for less than $3k since it does not support the latest surround formats eg Dolby Atmos, DTS-X, Auro 3D nor 4K video pass through, HDR, hdcp 2.2. The original msrp was $5k. It’s now been replaced by the Sigma SSP Mk2 which supports the latest formats and the current retail price goes up to $6k brand new. Classe upgraded audio video boards with the Mk2.

The same to be said for the Bryston SP3 processor. When I heard it the SP3 was used as an analog stereo preamp using its XLR analog audio inputs in analog bypass mode. They had a PS Audio Direct Stream DAC as a digital front end source component at the time feeding the Bryston SP3 via XLR analog audio. IMO it sounded really good coming from a HT processor but I have never tried the Bryston SP3 for surrounds using its HDMI inputs or never tried its digital inputs at all, so had no idea how it sounded using its digital inputs thus using its DAC, DSP, etc. When used as an analog stereo preamp using its stereo analog audio input (XLR) IMO the Bryston SP3 sounded better than both Classe SSP 800 & Sigma SSP.
The Bryston SP3 is similarly priced as the original msrp of the SSP 800.

In regards to Datasat and Trinnov processors I completely agree with you they both are great for surround processings for HT use but their analog stages are not any better than the Classe or the Bryston SP3 or the Meridian Ref 861 v8. I think I also mentioned that in my earlier post.

In regards to Marantz AV8802 processor, yes it sounded good for HT use when using its HDMI inputs but when we tried its stereo analog audio inputs (XLR) again fed by a PS Audio Direct Stream DAC via analog it wasn’t quite in the same league as the Bryston SP3 or the Classe Sigma SSP or the SSP 800 or the Meridian Ref 861 v8.
We still felt the need for a dedicated high end analog stereo preamp for stereo listening to music. But yes the Marantz AV8802 performed very good for surrounds for HT (movies) especially for the money.

I an still using the Classe SSP 800 in my dedicated home theater room paired with all Classe Delta series amplifiers (class AB) driving all B&W 800 D3 series speaker system and they sounded spectacular together. But this is strictly for HT use. I have a separate dedicated stereo setup and system in a separate dedicated stereo listening room which consists of completely different gears.
I am about to get rid of my Classe SSP 800 as it’s getting obselete.
I’ll be looking for a new processor that can decode Dolby Atmos & DTS-X pretty soon.
I've been following this discussion pretty closely as I'm in a similar pre-pro decision making point.
Excellent 2.0 listening is the goal, with decent 7.1 HT capabilities desired. I have no desire for any Atmos, etc. 
Video will be direct from an Oppo 205 so I do not care at all about pass-through/ switching of the pre-pro.
All audio input would be either XLR for FL/ FR (vs combo XLR/ RCA analog for 7.1) or HDMI with the source an Oppo 205. All other sources would flow through the Oppo, so I really do not care about the input aspect of the pre-pro.
Therefore the Krell Foundation and Classe SSP 800/ Sigma are all pretty equal for me.
The one aspect I'm not excited about is the limited output connectivity on the Classe Sigma range.
However I'm wondering about the advantage/ disadvantage of RCA ended vs XLR interconnects for the 5 surround channels.

BTW, 

I just wanted to comment that the Classe SSP is doing what the Theta Casanova used to. Convert all analog inputs to digital, use DSP for crossover and EQ.  There was no pure analog pathway in it. 

I also loved mine. I upgraded mainly to get a more modern DAC and HDMI compatibility.

Nope. The Classe SSP 800 & Sigma SSP do not convert their analog inputs to digital. There’s an analog bypass feature that you need to choose.
It will however convert it to digital if you choose to use their crossover and use the manual PEQ with the analog audio inputs. But if one wants to use their analog audio inputs most likely will bypass DSP and other digital processings. But you will have to tick that analog bypass otherwise DSP and other digital processings gets in the way.

Yep, caphill is correct in that most processors will have a true "analog passthrough" mode.  It's correct that it will not do bass management/crossover, since you are just sending 2-channel analog directly through to the left/right speakers only.  Even Krell has a mode like this.

For HT digital sound quality, caphill may be correct.  The differences in sound quality for 2-channel analog passthrough introduce a new segment:  the analog input stage.  This can actually make or break the sound quality of an HT processor when used as a 2-channel analog preamp.  If caphill is saying that Sigma is better for 2-channel analog, then Classe may have built a better analog input stage.  The SSP-800 was really intended for HT processing, so the analog inputs stages may not be as good.

I do know that the Bryston SP3 uses another set of their discrete Class A circuits for all 8 channels of the input stages, so caphill's comment about the SP3 being great for 2-channel analog audio could be correct. I still don't like the SP3 architecture - where they have a big main power supply, but no localized power supply capacitors around the actual analog circuits.  I have found through R&D that this lack of localized power supply will give you softer mids/highs and a lacking in attack/resolution.  To each their own, though.  One thing I like about Krell Class A circuits is that they have a lot of localized caps (typically soemting like 6 x 47uf capacitors around a single channel audio stage).  This gives them extreme amounts of attack and resolution.  However, the Krell main power supply is typically undersized (especially in their HT processors) so that you get the typical Krell thin/bright sonic signature.
