In Reply to: RE: Tubes don't measure well, but they can sound amazing. nt posted by ppopp on June 28, 2014 at 19:08:46
Hi and thanks a lot for the valuable suggestion
I found it and it is very nice actually
I spot tubes inside ... many people say that tubes have a magic touch with digital
By the way you mean "PCM 1704" ?
Because i read
" DAC60 chip use famous PCM1704, at the same level of world's top DAC "
So is the magic in this chip ?
Thanks a lot again.
Kind regards,

Its a good DAC for the DAC chip and for the analog output, which uses no opamps or transistors at all.
Thanks again for the valuable advice
I read something about op-amps
The first thing that hits me is the huge open loop gain
But i feel than in a phono preamp this could be useful
I would like to listen a phono preamp powered by batteries ... i am curious about Sutherland Engineering preamps for instance
For the output stage actually the use of opamps looks a little strange
Very good output stages can be made out of discretes i guess
Lately i have discovered LTSpice and i am playing with it
It is impressive, at least on the paper, how even very textbook circuits can give very good performance selecting the right working conditions
I have ordered some breadboards ... i am curious
Thanks again
Kind regards,

Op-amps?? Yuck. IME they almost never sound good. They require a ton of feedback just to work properly and they are often a dozen or more transistors in a package. No thanks, I will stick with tubes in my phonostage.
