An unique feature of the EAR (with volume option) is that you can connect it directly to your amp. This may not appeal to everyone, but for signal path purists and passive pre advocates, it doesn't get any better than this.
I just discovered the EAR costs quite a bit more than it did in 1998 when the SoundStage review was done. I should have known this, but I thought it was still around $1000. The distributer just told me:
The retail for the black version (with or without volume) is $1595. The chrome version retails for $2195.
If the EAR is out of your price range, I'd recommend the Black Cube or a Musical Surroundings Phonomena over the Dynavector P75 or the CIAudio. For under $500 used, IMHO they're the best sounding phono pre's you'll find. I've heard the Black Cube and I own the Phonomena. A review of the Phonomena can be found here:
But before you buy a phono preamp, you should be thinking about cartridges. The two go hand in hand.
Best of luck in your decision. -Mark
