I have had nothing but good experiences with MSB. I have a Link, a Gold and a Platinum. My main system is a dCS Elgar and a 972 upsampler. The Platinum is very close to the dCS and that's even before their new upsampler board which I should have from them in two or three weeks.
I have no business interest in the company. I don't know of quality problems. Perhaps a specific reference to the publication where the quality problems would be helpful.
MSB is located in one of the highest cost labor markets in the world, here in Northern California. Their prices, based on the boards/parts inside, from my professional experience in electronics are a bargain by High End standards and well priced by typical small run electronics standards.
Moore's Law has made for tremendous progress in the quality of DAC's over the last few years and there are very good ones at every price point. MSB units are way up there in terms of price performance.
To a specific point raised above. Any DAC's performance can be significantly improved with a better power supply and that certainly applies to the Gold.
