Hi-fi system resolution has long been the cause of heated arguments. But when it comes to converting digital data to an analog signal, there can be no argument. Data go in at one end of a DAC and an analog signal comes out of the other end, with a noise floor directly rated to the combination of the converter's digital and analog resolution. Ever since I started measuring digital products for Stereophile, I have been expressing a D/A processor's effective resolution in terms of the equivalent number of bits.

I consider Charles Mingus one of the great American composers, at least on par with the most celebrated American classical dudes. With apologies to fans of that music, I'd much rather listen to this record, or any of several other Mingus recordings, than, say, Billy the Kid or Rhapsody in Blue. What makes Mingus great is precisely that, in contrast to Copland and Gershwin, when he explored the vernacular, it wasn't some pale imitation.

I am proud of the fact that my first review for Stereophile was of a modestly priced integrated amplifier called the Rogue Audio Sphinx. Specified at 100Wpc into 8 ohms, 200Wpc into 4 ohms (footnote 1), it played the KEF LS50s like it was made for them. It was simple and handsome and cost only $1295, phono stage included.
