Hi,
In the review of that amp Herb noticed a faint Lutron-dimmer type buzz.The sound he detected was coming from the amp in the transformer region.He used a stethoscope and presumed the transformer's coils were being amplified by the aluminum chassis and the diaphram of the 1920's wood floor.
He used this isolation base, the Harmonic Resolution Systems M#X 1719 AMG GR LF and the buzz was reduced to serene inaudibility.
I wished he explained the science behind the base and the amp.If that platform worked that well to silence a transformer hum I'm ordering one tonight.
I like the way Herb tests all sorts of equipment variations but in this review I think he spent more time on interconnect interaction with the amp than needed. Maybe a standard good quality interconnect should be the norm for testing.
It was a good review but left some questions for the customer.Here's one.
Does Bill build the boards or are they outsourced ? Thanks Mark K.
