My listening room is approx 20 x 18 x 8 on a second floor that is suspended and open to the lower floor. Room is carpeted and is not treated. My Sf Electa Amator III and Gravis 2 sub are on the long wall along with my LP storage rack. Equipment is along the adjacent wall - C2300 pre, MC275MKVI amp, ps Audio P12, VPi SDS, Bryston BCD3 and PS Audio Stellar phono stage. At times I like to listen to music >100dB and when I did this I would get terrible audio feedback through my tone arm. Ivan’s knowledge and expertise fixed that annoying issue for me. My VPI turntable now has Stillpoint Ultra 5 as the supporting feet on a HRS M3X platform sitting on the marble top of my equipment console. All feedback has been tamed even when the sound is >106dB (approx 64 watts) and sub is making the suspended floor vibrate. Even though this fix was not cheap we all know with this hobby we are always reaching for that last 10% improvement no matter the cost, to a certain extent. Ivan’s diagnosis and solution fixed this issue I had experienced since moving into the newly built home in late 2012.
