Cayin A88T break in and biasing??


Just took a Jolida 302BRC back to a dealer to
get the A88 instead. I loved the Jolida no doubt,
but assumed the A88 would be a step up, and so far
all I can say is it has the potential but sounds
a little hard & brittle now.
Just wondering if anyone has had experience with it
and does it get better with time?
I need to know before I go drop another 1k on it.
Also...I never could get a handle on whether or
not the amp is self biasing or not?? Most people
say it is not and you have to take it out, flip it over
and bias it....that's crazy and would be a deal breaker
for sure!
Any help or thoughts on this would be greatly appreciated.

BTW... I only had about 6-7 hours on it when I started
to give it a listen.

Aball,

So he didn't get it from VAS Audio? I agree with you, definitely some variations out there.

I purchased mine from a dealer in PA who got it from VAS. I also noticed that some other A-70T's on the net that look somewhat different. There's some type of switch where mine has the bias adjustment and bias test points. Here are two pics of mine, including manual, fwiw.

I have a Cayin A-70T and this is NOT auto biasing. There is a section in the manual which details how to bias the tubes, complete with recommended voltage settings. It's really a very simple process and you don't have to move a thing to do it, other than lift the cage off.

I searched the net as well and found that the lower wattage models state that those are auto-biasing. Maybe there's something about the US Version (VAS) vs. the others.
