Agree, but just noticed it as there seems to be a gap between $69 amps and "real" ones. Not everyone can jump to a JC-3 or Roland.
Matching the input impedance is bigger difference than a lot of the amps. I wonder as I have seen setups with a very high end amp and switching cartridges around but no easy way to change the impedance. When I ran a table, all there of the preamps I went through were soldered in resistors and capacitors. There was a big difference between Grace and Otophone! I had a Micro-Seki? or something that had the matching network built in, but the Grace was nicer. Long time ago.
