This prowess, however, wasn’t dependent on the superior pressing at higher speed. With the 2014 reissue of Etta James’ sublime Tell Mama on Bear Family [BAF108026], certainly not known as a label of the audiophile tendency, the otherwise average recording did not hold back one iota of James’ peerless, powerful vocals on this milestone LP.

You want emotion? Here Etta James rips out your heart, and the Sigma 170i ensured that every dynamic moment was treated with respect. Damn, this is a fine amp.
