Hello All -
When my power amp is plugged directly into the wall outlet, the same as the Quintet, I have a very low level ground loop buzz. You only hear it with your ear right next to the tweeter of the speaker but you do hear other effects such as low level ticks and crackles in quiet parts of music that does not otherwise have these issues.
When I plug the amp into the Quintet the buzz goes away as well as the other artifacts but I feel some of the low end is lost when the amp is plugged into the Quintet. Previously, I had an integrated plugged directly into the Quintet and hence just discovering this after years of use. So, I appear to have something odd between the two outlets on the same receptacle.
If I purchase a new P12 or P15 do you feel the issue I am having with loss of of low end (deep low end), will return? The manufacture recommends plugging directly into the outlet. Honestly I only discovered this with the introduction of new DAC that has outstanding low level detail as it revealed the issue. Just to be sure I removed the new DAC and the problems remained. It just let me discover them.
Thanks for any advise or input
