Not a household name by any means, Keene was a star in the world of indie rock. In a world populated by literally thousands of guitar players, Keene's sharp, extra crunchy guitar tone was distinct and unmistakable. His songwriting, indebted like all power poppers to The Beatles,…

The NAD M50.2's analog inputs have an impedance of close to 20k ohms, and the analog input signals appear to be converted to 24-bit digital with a sample rate of 48kHz. Playing a 1kHz, –20dBFS tone from Editor's Choice (CD, Stereophile STPH016-2) on my Ayre C-5xeMP player, which has a maximum single-ended output level of 2.1V, resulted in digital data with a maximum level of –21.35dBFS. The gain of the M50.2's analog inputs will work well with sources that don't peak above 2V RMS. The resultant digital-domain spectrum (fig.1) had a clean noise floor, with the…
