Claudio IL Benna Posted June 10, 2021 Share Posted June 10, 2021 Nice spider, how is the background noise? I had one of these chinese valve amps in the past and there was quite a bit of hum. Cheers Link to comment Share on other sites More sharing options...

When I hook it up with another chinese tube power amp, dead quiet. When I hook it up with DIY Spud Kit amp, there is slight hum. When I hook it up with Emotiva powered monitor, quiet. So far, only slight hum that I could detect is DIY Spud Kit amp but not sure why it is. my guess that there is a ground loop between the two somewhere? If you have similar valve pre and have the hum, may worthwhile to check the grounding for both components? I am sure that there are gurus in this area in this forum who might be able to help with your valve amp. Thanks. Link to comment Share on other sites More sharing options...

BRS Posted June 10, 2021 Share Posted June 10, 2021 It's funny. The more I look on Stereonet the more I see stuff I want. I even looked to see if it would connect to my integrated (it won't no direct input) but it would look good in my listening space though. Not to mention I am in Sydney 1 Link to comment Share on other sites More sharing options...
