Sorry but nobody comment, or suggest something about the original topic...
Still
By the way the picture of BUF634 is actualy internal sch of LH0063
as we can see noted on picture itself... Sorry thart was mistake in name...
LH0063 as well as LH0002 can be used for that topology also.

I'd personally take the lazier approach and just swap + and - on my speakers...Jocko Homo said:Those of us who make non-inverting I/V stages, and are lazy, invert the data going into the filter chip............

Hi Zoran,
Your circuits are implementations of fast OP's. You can try various OP's (which sound different), but the biggest difference comes from properly executed PCB - ground topology and power supplies.
I would personally avoid your idea for phase inversion, because it introduces unnecessary extra-wiring and will deteriorate the sound a lot. In particular if you use shielded cable to feed the analog-out to "phase invert block”, as you intended in post # 19. I would do it in digital domain where the effect on sound is minimal. The analog wiring from analog-out to RCA’s should be simplest / shortest possible, and not shielded. Try loose twisted pairs.

Sorry but there is no phase inversion...
The signal comes out in-phase.
I think that modular topology can be usefull for
simplier modular designs of dacs for the example with
TDA1543... Because it is compact, simple, gives a right phase,
and sounds excellent...
I tryed very simillar design but with descreete components
not matched at all it was much better then standard factory
design applyed...

Try 2SJ109 / 2SK389.

hi,
Here in europe www.schuro.de is cheaper, if they reply, haha
