Tom-here's my room/setup
Room 15x20x7.5
At the long end of my room is a area that extends 3 feet longer than the room and is 6 'wide with same ceiling height of 7.5' There are treated windows.
The speakers are 4 feet from each side of the extention and 4 feet from the front wall.
The rack is in the extention as is all my dedicated outlets.The TT wall stand is 4.5 feet up over the stand.The steel support is bolted through my house wall and the nuts are on the outside siding.Every TT I've had I had acoustic feedback but was able to eliminate it with added weight on the TT shelf.3 TT's were non suspention and this is the 2nd suspention TT I've had.
I cant move my rack/stand d/t room setup.
I may need better advice how to set up the Delphi.
I have a ground from the interface box on the back of the delphi to the Creek.I added another ground tonight from the box to the TT steel support and it lowered the hum ~25% more.
Could the 65 gain from the Creek cause the hum?
I have a cheap linestage (tubes) could some better tubes (NOS) lower the hum?Its dead quiet with CD/tuner.
Without the clamp the acoustic feedback is really a non issue.I have to crank it louder than I would normally to get feedback.I would like to figure this out though so I can use the clamp.
Any other tricks to lower the hum with better grounding? Cheater plug maybe?
BTW Tom,The Denon is a special p.u. It reminds me of a Ortofon MC-20 super I once had,only smoother and more transparent.
