You need a light but rigid base for the Rega.They dont like to sit on a heavy base. I have a wall mounted shelf with a Bright Star Audio Big Rock #4 under my P-25.It works great.I had acoustic feedback until I installed the shelf and bought a rock.I wouldnt use anything heavier than a #4 under the table.Its the perfect size rock for Regas.I got mine at Audio Advisor for $90
Isolation for my Rega 3
My Rega 3 has very little accoustic isolation. I have a SACD player that is now vastly superior to my TT sound. Need to improve my analog. The music is clearer if I get someone to hold the Rega while playing. This is not recommended, and didn't do it with my favorate records, but the sound seems to be cleaner. What have people used to reduce accoustic vibration? Sorborbane feet, Air Mass, Big Rock, or whatever?
