I agree with Mofimadness and a few others that you may be dealing with "acoustical feedback". I had the same issue in a console. My turntable was producing a lot of hum when using my turntable and turning the volume anywhere past 11:00. I ended up getting an amazing isolation platform from Symposium called the ISO Segue! It solved the problem immediately- quiet as a mouse!
Bass distortion-Playing LP's only,,,,please help
VPI Prime----Ortofon Black Quintet (low output moving coil cart)-----Plinius Koru Phono Pre( loading at 20 ohms/gain at 66 db)-----Parasound Halo Integrated -----Martin Logan Montis speakers which have powered bass cabinets.
Using any other source component I have absolutely no issues. When I play an LP and increase the volume past 10 O'clock which is a little loud....but not ridiculously loud-I at times get this huge wave of bass distortion. I do have bass controls on the Montis's...and I have turned them down into the negative, but I still get what I previously described occasionally.
Any and all help would be appreciated. This doesn't always happen, but its frequent enough to drive me crazy.
Thanks in advance.
