I tend to judge caps by the specs, those old roes will have been high on esr so if in the signal path acting like a filter. Its gets warm in there so I'd have gone for 105 degree caps, probably fm or fc from Panasonic. When I redid my 200 and 7b pre I used fc everywhere. Made no difference in the pre, big difference in the 200.
Are those caps I the new AN caps with the powdered graphite filler? If so they should like the BGs, they've been trying to make them for years.

They haven't managed to replicate the Black Gate. They are still working on it.
Here's the gumf
"The Audio Note KAISEI range have been developed over the past 4 years with the engineering team at Rubycon (of Black Gate fame). They are based on the same materials with the only difference being the paper used is not impregnated with graphite particles. Otherwise the KAISEI capacitors use the same special electrolyte.
These Black Gate replacements are incredibly close in performance to the highly regarded WKz range. There aren`t any other capacitors that come close. Audio Note`s higher Level Three products, the Silver and Silver Signature models will have the KAISEI electrolytic capacitors in the power supply.
The same foil and paper and construction quality as will be found in the forthcoming Audio Note Black Gate replacements which should start coming through in the near future."
Not sure why they can't manage to replicate them But i would suggest after 4 years of trying they must be getting nearer.
I didn't find any information on the heat tolerance. The Panasonic caps I bought were 105c rated but that information doesn't appear to be available for the Kaisei.. I've presumed they must all be 105C....could be a costly presumsion.
if in doubt they're 85's

I think the difficulty is getting the graphite impregnated paper right, which incidentally is what really makes a Black Gate a Black Gate.

Today's little task was to remove the recently installed Panasonic caps and replace them with something of sufficient quality. Enter the AN Kaisei caps.
The initial impression upon a quick listen is that resolution has improved massively and the natural sound that had been slightly lost is back with a vengeance!!! I'll give them a week and then listen critically but I already know it's an improvement.
£36 for four. BARGAIN!!
A few pics:
Is there a screw missing from one of those crimped terminals?
“Music has always been a matter of energy to me, a question of fuel. Sentimental people call it inspiration, but what they really mean is fuel. I have always needed fuel. I am a serious consumer. On some nights I still believe that a car with the gas needle on empty can run about fifty more miles if you have the right music very loud on the radio”
