ASR Basis Exclusive or Einstein The TT's Choice

Rich, let's just say all the other Einstein components are tube based, while the phono stage isn't. I would put it up against *any* phono stage, tube or solid state, regardless of price.

All of Einstein's components contain tubes. Therefore, when they built the phono stage, a requirement was for it to have tube like sound to match the other components. The first time you hear it, you will swear it has a tube character to it's sound.
The round shape of the preamp enhances internal cooling and results in better cancellation of any sound resonances generated within the case. They are reflected back into the center of the case where they meet and are therefore cancelled out. The power supply has a much higher quality PC than one would expect.
There is a long umbilical cord connecting the two pieces, so you can keep them far apart. I found the sound improves somewhat as you move them further apart. Any potential for hum is eliminated by the separation.
The balanced unit has two power supplies and they also should be distanced from the Pre's. I have the single ended version and no listening experience with the balanced unit. If you have balanced tonearm wiring, the balanced version is supposed to be about 25% better. Makes sense since more isolation of the circuits and balanced from cartridge to amp. This judgement from those that have heard both versions.
The simplistic plug in load resistor approach makes changing values quick. I don't even have to power down. Took the sleeve off one and found a resistor soldered on a high quality rca plug with silcone fill added. You could replace the resistor with any value to customize to your own loading requirements.
I am really enjoying this component and so are the other owners I have talked to. Good example of great performance without spending obscene $.

I have the balanced version of the Einstein phono stage, while others I know have the single ended version. I haven't heard them side by side, although Sabertouch's description of the differences is in line with what I have been told. The dual power supplies of the balanced version help, as it is two completely separate mono phono stages, and yes, keeping the power supplies as far away from the units as possible reduces hum and noise. The stock power cords are pretty good, which may come as a surprise to some. That said, the unit does benefit from some aftermarket cords, although they are not compulsory.
