DAC Choices - $5,000 to $7,000

Sound in an abstract way is equally wave or bits, but in a concrete room sound is mostly only specific space and waves for specific ears, not bits....

You are certainly correct about that!

I have installed bass traps in the front wall corners and acoustic panels along the walls to tame treble reflections. When I am seriously listening, I cover the big screen TV with a blanket.

I have not spent the time to understand and analyze noise in the electric line and what are the typical ways to address this.

Another area I want to understand better is the relationship between the DAC output impedance relative to the preamp input impedance, and how much of that can you hear...

While the Theta DAC is better in terms of mids, highs and soundstage depth than my old Hegel HD25 DAC; the Hegel mid bass was better. That sort of indicates to me that I should continue to experiment with DACs.

I also want to experiment with balanced outputs to the preamp from the Theta, which I believe is fully balanced. I have read taking advantage of that will improve the sound.

As I reread this thread, the Mojo Audio Mystique V3 DAC looks interesting. Just so many good reviews and I appreciate the design philosophy. Right now they have a refurbished V3 balanced for $4K with two year warranty.

The only problem with balanced is the need to change from my CJ 17LS2 preamp, which is single ended only, and why I am contemplating a Don Sachs preamp. Don and I have been trading emails and he assures me that his preamp will seem like a veil has been lifted from my speakers compared the CJ. He seems like a straight forward person who shares what he believes and is willing to challenge his customers.

Thanks for listening!

@dsper Unless you want your dac quest into having to rebuild your entire system, maybe best to stick to choices that will work well with your existing components that you already own and like. Also every dealer and manufacture will claim their product is superior, I wouldn't take that at face value without getting independent references from those who have made a direct comparison between two products. Even then everyone's system, ears and preferences are different, there is no substitute for hearing it in your own room.

@yyzsantabarbara - Thanks for the AudioByte recommendation but the DAC ship has sailed for me, at least for now.  I sold my Metrum Adagio and like  @ddafoe, I am currently enjoying the Mojo Mystique V3 Balanced.  I actually like it so much that I will (hopefully soon) be receiving a new Mojo EVO B4B DAC.  Benjamin at Mojo is helpful with trade-ins so I can keep the V3 until I receive and try out my new EVO. 

At the same time as I await my new EVO DAC, Steve McCormack is building me an SMc Audio UltraDAC G (or whatever he will call the highest level he can do with the McCormack DAC-1), which will include the new board they have made for the McCormack DAC-1 and also their Gravity Base.  The UltraDAC will be limited to Redbook resolution but some folks believe it sounds outstanding within that limitation.  Since probably 95% of what I listen to is Redbook quality, and since I trust the results of  Steve's work, I will keep an open mind.  It doesn't hurt that I need two DACs so I can keep both. 

@dsper - FYI, no need to rebuild anything as the Mojo Mystique V3 Balanced also has single-ended inputs - and so does their new EVO DAC.  I run my gear balanced so I have not tried the single-ended inputs but you could maybe take a look at the reviews and whether any of the reviewers tried it through the single-ended inputs.  You could always contact Benjamin and ask his opinion as to the sonic differences between using the balanced and single-ended inputs.  He is quite responsive to questions.

I have the EVO and use RCA SPDIF connection, very musical to my ears. Whether or not the balanced connection sounds even better I can not say , but from my experience the single ended connection is very satisfying

For people still shopping, another contender seems to be the Sw1x dacs. R2R with tube output stages. I've seen nothing but praise. I think that's the next one I'll try (either the III or IV).
