efung, again, thanks for the fantastic info. Is any generic (eBay) DC-DC converter adequate for isolating the ground plane? Do you have a product on the market?
NJM has been called "ghetto blaster" quality in the DIY community. Agree with the substandard sound quality. A few months ago I got a deal on Icepower modules 125ASX2. These were in VocoPro Feather amp FA-500 selling for $87 shipped in US clearance Beach Audio through NewEgg. The preamps in these were loaded with NJM op amps. Sound quality was substandard. Pulled the Icepower modules, trashed the rest of it.
