Ever since I built my trussed house back in 1991 I have never been able to listen to Lp's with any volume. I have 2 old turntables that work Technics, and a Pioneer. Both use B&O MMC3 cartridges. I have to record records on my old Nakamichi CR4 Cassete deck. Then I'm able to listen at higher levels. This also helps preserve my collection. Gee does that really date me.. What kind of isolation devices are availible? I've also tried long patch cords to get the turntable out of the room, but I find this rolls off the higher frequencies.
