Today I had the opportunity to listen with the Durand record weight in two systems.
First we listened at Mike Lavigne's. The improvement was small but consistent: improved high frequency clarity, more weight to kick drums and bass, better definition of individual performers.
At my place with the Galibier turntable, the changes were of a similar nature but substantially more conspicuous. In my system, the noise floor also dropped, something that was not discernable at Mike's.
Before today, I was pretty dubious, but after today's demonstrations, I'm a convert...I hate to spend the money but it in my system, it's worth the expense.
After the Newport Show, I'm going to help Mike install his Herzian active device under his NVS...I'm interested if this will negate the effect of the weight...to be continued.
