PS Audio GCPH phono preamplifier
PS Audio's first product, back in 1973, was a standalone phono stage; more recently, their PCA-2 preamp had an optional phono board. The <A HREF="http://www.stereophile.com/solidpoweramps/106ps">GCC-100</A> integrated amplifier that I review this month has no room inside for a phono board, so they've gone back to producing a separate phono stage: the GCPH ($995). Like the other products in PS Audio's current line, this one is based on the Gain Cell, one module on the input side connecting to the cartridge, followed by a passive RIAA curve (with a claimed accuracy of 0.1dB over the 40dB range of the curve), and another Gain Cell on the output side.
