Tube rolling in Cayin A-88T

Which speaker terminal are you guys using? There seems to be a pretty good difference between each one. The flexablity this amp offers is a strong plus. You can change tubes, switch between UL and Triode, and use different speaker terminals.

I've tried all the taps and definately prefer the 8 Ohm. In my system the 4 Ohm limits the dynamics, bass..everything is flat sounding. The 16 Ohm is a bit bright..8 Ohm perfect! I listen exclusively in UL mode. The Triode less coherent and < dynamic overall.

Just biased some Re-Issue Tung Sol 6550's and they sound very good indeed. Bass is not quite as prodigious as the stock tube.. being somewhat less focused, but the mids are more lush with a nicer top end IMO.. A Very listenable tube/ Im sure they need to break-in for a time.

I just got one Cayin A-88T, unbelievably it sounds a bit harsh compared with my TEAC DR-L700, a tube amp !!!

Should I use supports with it, or is it unecessary ?

Lowrider, How much time do you have on the amp? Break in of tubes as well as the amp itself is quite important. If you have less than 100 hours on a new tube amp I'd reserve judgment. Ultimately though you might roll in some warmer power tubes (I like SED KT88's) and/or some NOS small tubes.

"harsh compared to TEAC". Are you refering to TEAC that japanese c**p that came out in the 70's?
Spam. The Cayin needs zero breakin time btw Newbee.
