In the October 2012 issue of Stereophile magazine Jon Iverson reviews the top-of-the-line MSB Technology Diamond DAC IV, configured with the optional FemtoSecond Galaxy clock, Diamond stepped attenuators, iLink II iPod dock, plus both USB2.0 384 kHz and PRO-I2S inputs. The “fully loaded” Diamond DAC IV, powered by the matching Diamond Power Base, was partnered with MSB’s Data CD IV with matching Signature Transport Power Base.

Mr Iverson says…..

“JA had sent me the magazine’s loaner sample of the dCS Debussy DAC. I’d warmed it up for a few days and…. there was no mistaking which was which. The Debussy has lots of detail–everything is there–but, as JA has noted, it’s a bit “laid back.” I would suggest that it just lies there. Clearly refined and very polite, it would be the perfect guest for your formal dinner event, and I’m sure it has its advocates….. the MSB had better focused imaging, and I felt it brought us a generation or two closer to the original master…. Images were better defined and appeared more naturally in space with the MSB compared with the dCS.”

“The MSB stack gave me the best digital sound I’ve ever heard in my system. I know it’s a cliché, but I was digging out music from all corners of my collection, just to hear it “real” before the MSBs had to go back.”

Michael Fremer, who currently has an “MSB stack on loan,” is also quoted in the article:

“It’s ironic that I’m starting a new analog website ( when I’ve finally found great digital!”

Editor John Atkinson ran his usual gamut of objective measurements and concluded:

“In most ways, MSB Technology’s Diamond DAC IV offers the best measured performance in the digital domain that I have encountered.”
