6SN7 and 6SL7 tubes recomendations (Cayin A88T integrated)

Hi everyone,

my integrated Cayin A88T uses KT88 as power tubes, and 6SN7 and 6SL7 as preamp tubes. I would like to upgrade the tubes, what would be the best options with new tubes (not NOS)?

It seems that 6SN7 can be substitued by cv181, but their are many nrands an models. The same for 6SL7, many option (Shuguang, Psvane, Sofia Electric...).

I'm currently using TungSol new tubes. Already have some NOS (RCA, Silvania), didn't like them (less detailed, not so open sound stage...).

Thank you.

Hi, thanks everyone for the replies.

Yes I checked the bias of my amp, and it was also serviced to check the inside regulation of the bias (some A88T have problems with that).

I currently use KT88 Genalex Gold Lions, said to be the best with this amp (?).

I wondered how they compare to Psvane KT88. I gave up switiching to 6550 which doesn't have to bring any advantage.

Regarding the 6SN7 and 6SL7, I will check the other topics. Linlai is quite new on the market, Psvane, Shuguang are more well-known and have more feed-backs on the web...
