The Gram Amp 2 SE is a MM phono pre. Its input range is 2 - 9 mv rms. I've rated it 8/10 for age only. I purchased it new in 2006. I'm leaving MM territory for the bewitching shores of MC land, hence the sale. The PSU-1 power supply alone goes for $299 new - I bought it somewhat later and found it to contribute a noticeable improvement to the sound of the Gram Amp 2. I would prefer to sell both items together. I'll cover shipping within the US only, others please contact me with your postal code for a shipping quote.
