4/30 Update: Added pictures, and a price drop.
This Usher pre-amp is an incredible bargain (as are all Usher products). At $2200, it uses high-quality Japanese parts that are used in preamps that retail for $10,000 and up. (Just take a look at the insides in the stock photo, and compare with any product you want in terms of quality of parts or layout.) I am only selling because I bought a Music Vault as my source, so have a purely digital system with the Benchmark as my preamp.
Here is Usher's description and specs: Usher P-307:
USHER P-307 Stereo Preamplifier
P-307 is the control center of today's high end sound systems. Its two main functions are source selection and volume control. Every effort has been made to keep P-307 as accurate as possible.
To avoid unwanted interactions with adjacent source components, P-307 uses high-quality relays and switching designs to ensure that every source is intact. Thus all sources remain separate from one another and from the power amplifier and cables.
In the digital age, analog preamplifiers remain the most reliable and neutral-sounding component of controlling volume. P-307 uses a superior attenuator that offers a neutral sonic performance.

I have the original boxes, and will ship quickly and safely. Check out my feedback here (or I'm happy to provide my perfect feedback on head-fi, ebay, etc.) and buy with confidence. The last time this pre was offered here it sold for around $825, and I paid much more than that for mine, so you're getting a steal.
