Hi Vitaly, have you tried any other OP AMPs besides the 1656?
Thanks

LM4562, OPA627, AD8066, OPA1632 in new board.
OPA627 better,

Hi Cardone! I tried this little tube preamp ...
I deleted it .... I thought it would sublimate the sound ...
It adds distortion!
Well I put it back in its box!
Too much loss of detail. Really the tubes have killed the performance of my dac.
With an AKM dac, the sound is just perfect! (I tried dac saber ... the sound tired me in the high of the spectrum) Have a nice day !!!

Hello Mamocel,
when I hear the music softly, there is no distortion. As soon as I turn the volume up, the distortion occurs.
Otherwise it's okay ...
Greetings and Happy Easter
