looks excellent. this build is an excellent excuse to get out your whackiest looking NOS polypropylene caps 😉 the juxtaposition between high end modern SMD and old world whackiness is superb!! but its all about the sound of course 
anyone looking at possibly using the linear systems stuff? I agree active devices are an excellent opportunity to play with the sound as well. especially in a reasonably simple/elegant circuit, it is a good opportunity to hear the differences in everything really, with such resolution to back it up.

Russ,
Do you mean:
Between + output and GND = AVCC/2 ?
Between - output and GND = AVCC/2 ?
Between + output and - = 0 volt ?
Thanks,

Trimmers adjustments

And another question:
If I replace the DC coupling capacitors with film cap (MKP,tin foil,silver oil ....) will be any sonic improvement.
Which is the most suitable type and capacity for this ?

Film caps instead of electrolitics
Of course I have installed the supplied caps and I am listening to them now.
The question is if I replace these with film caps will be any improvement.

Nice and tidy build.
If you are going to be listening single-ended, can I suggest that you swap the op-amp you are using for a LME49720HA (the metal can variant). A subtle but worthwhile improvement can be had by doing this. I've found this several times, in headphone amps and also in the ballsie for my B32S.
Thanks.
It is running SE now.
The biggest task was modifying the case. The Legato is hungry, and is producing a lot of heat.
Since I don't have a CNC, I had to drill holes. Lots of, 2^8-1 holes, phewww - 😀

I'm not saying that caps are BAD. Caps can be compact, inexpensive, and decent sounding.
I simply dislike large and expensive exotic capacitors in this application. IME, a pair of decent transformers are usually cheaper and sound just as good or better.
I think he meant this link: http://www.diyaudio.com/forums/twisted-pear/164294-buffalo-ii-transformers.html
Interesting...
Opinion, chips. I will be running my Legato with Mundorf zN film/foils (running balanced only) these were the best caps I could reasonably fit in my chassis design. I suspect really good caps are more transparent than really good transformers, but this is just a suspicion. Of course transformers also bring something else to the party, as they add distortion (could be pleasing) and they also isolate RF from their output (running balanced should cancel any RF anyway).
I do find it somewhat telling that some of the best preamps in the world (think Audio Research Reference) choose to use caps at the output rather than transformers (likely very expensive teflon films, I believe AR's are "proprietary").

Right, maybe that's the link he's referring to. Thanks for pointing that out.
Either way, I prefer to discuss Legato-related topics in the Legato thread 😀
Sorry if I wasn't clear, but I meant IME by my "past" experience with capacitor and transformer coupling.
Though I suspect that the transformers will remain my favorite, I do intend to compare them against Muse ES bipolars and Mundorf SGOs when I receive my Legato 🙂
