Re: First Hand Opinions of OPA627 vs AD8610 or others...

I used the OPA627's in my Classe' pre-amp mod and they work very well. I've also used the Buf 634 in my Linkwitz tri-amp system of years ago and to replace the H-Dams in my CD67. They work well too. Although I haven't used them together I would recommend you run seperate power lines to each device. The buffers can pull some current and you don't want it to talk to the op-amps through the power supply lines. I like to use a .1uF cap and 1000uF> at each power pin too. Good Luck, bobwire
