Binding post upgrade for Classe CAP-151?

If you are familiar with the CA-300 and CA-400, you will know that the way the amp is constructed, there is no room for bypass caps. The CA-300 has thirty-six 4,700uf filter caps, stacked in two tiers of 18. IMO, one of the DR models with their more open layout would be a better candidate for such modding.

I use only the balanced inputs of the classe CA-300. Therefore I have bypassed the entire op amp BB dual 2604 buffer stage print. The cables to the central amp print is now directly connected to the 3 white wires of balanced inputs. The white wires are disconnected from the buffer print.

This is the way go. This sounds so much better in every aspect This is a complete different amp. So much more detail, clean and power. Still warm and pleasant. Much more music :-)

If you would try, be carefull to isolate the connections very well. Dc is still on the buffer the print. I Did not disconnect powersuply of the print yet. Have to decide this later. (Use a Music first Audio classic as pre) Update will follow

I guess you don't plan on ever selling that CA-300. A future owner may want to use the RCA inputs.

No way of selling. its sounds so damned good now.

I guess I must look into that mod. :-)
