Question on OPA637

Posted by marchewd (A) on January 18, 2007 at 22:32:05

Hello,
I was able to get a few OPA637BP's for dirt cheap. I know that the 627's work well in my Music Hall CD25 (with Brown Dog adapters)and Jolida JD-9 Phono Stage. I was wondering if I could hurt either of these two pieces by trying the 637's in there? Or, if they are not compatible, would I just get hissing and popping noises? I realize that the 637's require a gain of at least 5 across the entire bandwidth, but I have no idea if either of these two units has that much gain. I was also wondering about trying them in my Rogue Stealth. It currently has AD797's in there, but it also has sockets for dual chips as well. I thought about trying them 637's in there in single mode, then trying them in dual channel mode (with the Brown Dog adapters). BUT, I do NOT want to try these experiments if it could damage my equipment. Any help would be greatly appreciated.

Thanks,
Dan
