I had a krell ksa-100 that I used with a don sachs pre for 3 years and no issues. I now bought a simaudio 760a and it goes into dc protection mode within 10 min of operation. The sachs does leak some dc at the outputs. Some amps just don’t jive with some tube preamps due to dc leakage. We just put the sachs internally and everything is fine. A transformer coupled tube pre is the safest bet. Krell usually respond very well to tube preamps. It might be that since the recap your amp is now too sensitive. It’s a journey man, it can be frustrating but it sure is fun.
Vacuum Tube preamp with my KRELL KAV 250a, a no no......WHY?
I have an older Krell KAV amp that has been recapped and refreshed. A technician that I respect very much said do NOT use a vacuum tube preamp with my KAV 250, or any other Krell amp for that matter. Can someone with more technical knowledge than myself tell me why I should not be using a vacuum tube preamp with my Krell? Are there some technical specs that I should be aware of when pairing?
Thanks
