Since I have recently improved everything else in my system, I decided to take the next step in the phono area as well.
I bought the Einstein Turntable's Choice which has a fixed gain of 68 db and, when paired with my ARC Ref 3 should deliver enough gain for the low output Benz Micro Gullwing which I also bought. I prefer the lower output cartridges and, after looking at all the factors, decided to just bite the bullet and upgrade.
I originally wanted a unit like the PASS XP15 since it is more flexible, but have heard raves about the Einstein and, so long as I stay with cartridges in the .25 to .35 range, shouldn't really need multiple settings. Hope that reasoning isn't faulty.
