Dear Sirs,
I bought the SV-237mk version because of I was impressed by the warmth, cosiness voices of it, it is my first tube (hybrid) amplifier. After a while I recognised the music from tube pre-amplifier is not enough detailed. (MK version had 6,3" jact to check pre-amplifier stage excluding room affect, power amplifier distorsion, etc).
Tungsram 12AX7 (ECC83) old production tube helped lot replacing the Chinese 12AX7B, but warmth become moderate, Tungsram behaviour more FET amplifier like and more accurate, sounds like a different amplifier.
(I changed Russian 6N1P-EV tubes as well to Tungsram ECC85 for test, but no significant change plus they are in breaking-in period already, so early to judge)
If I listen my portable Cayin N5ii DAC with Sennheiser headset as reference, I found significantly more details in Cayin N5ii music despite the Tungsram 12AX7 tube in Vincent (using Cayin as source in this case).
Could you write some recommendation to change tubes to something other than Tungsram, please or is the less detailing a tube amplifier behaviour ?
I saw several forum member satisfied with SV-237 (or SV-236), so you didn't found the same problem with detailing ? I like the characteristics of SV-237mk with original tube, just the detailed presentation e.g. in a guitar recording missing to my ears.
Did somebody listen the SA-T7 tube pre-amp ? What is your opinion, can it solve the detailing problem ? The technical specification is impressive, but opinion from a music expert could be fine, no listening room here to test.
(sorry if my English sometimes a bit basic, but English forums are the best in these topics)
