Binding post upgrade for Classe CAP-151?

Hello Gbart,

Could you hear the difference?

I own a ca-300 as well :-)

Replacing the Input caps is also an option.

Q1rene, yes, I could hear differences. The CA-300 has no input caps to replace. Trying different input buffer op-amps may or may not be worthwhile.

There are power caps in signal way on the main print.
In the upper right corner 2 indentical capacitor and a red wima are in signal way on this picture.

I replaced them a view years ago with 1 red black gate of 100mf per channel. I want to try siemens mkv later. If it fits somewhere:-)

Did you needed to change something to standard holes in ca-300 to place the wbt 702?

The two red Wima caps you're talking about are the two 0.1uf op-amp decoupling caps, C105 and C106. The 100uf caps must be the two +VCC and -VCC decoupling caps.

No modification to the CA-300 chassis was necessary to fit the WBT 0702 posts. However, you will need to reuse the stock Classé inside washer, followed by the WBT puzzle washers. Use the WBT standard washer on the outside, but you will need to trim off the little notch on it (see picture linked below) before it will sit flat against the inside washer.

The binding posts will help, but yr focusing on wrong area. Look more into filter cap bypasses. will make a much larger improvement.
