ASR Basis Exclusive or Einstein The TT's Choice

All,

How many pairs of inputs and outputs does the einstein have? I read stereophile's list that it has 2 pairs inputs and outputs. Is this true?

Andrew

The Einstein phono stage, available in either single ended or balanced version, has two pairs of input connectors, one pair of which are used for plugging in the load resistors. Four pairs of load resistors are provided: 40, 85, 150, and 300 ohms, fitted with either RCA or XLR connectors depending on which model. One pair of outputs is provided.

Brian,

Any thoughts on how the Einstein compares to a tube phono? Does it have the body and solidity of tubes?

Thanks
Rich

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 $.
