In the Oct 2008, I read Sam's review of the Grace m902 with interest as I'm considering a headphone amplifier and also "simplifying" my system at the same time, and the Grace m902 seems to fit the bill nicely.
However I am unsure what the Stereophile Recommended Components Class rating of the m902 as a preamplifier is? In the Recommended Components list, the m902 is rated Class A as both a DAC and Headphone amplifier but no mention of it in the Preamplifier ratings section.
It appears the m902 is "recommended" by Sam and others at Stereophile, but as a preamp is it worthy of a Recommended Components Class rating? If so, which one? 
Thanks!
