I have owned this fine, all-tube preamp for less than one year. It is in perfect operating condition. You can buy this on E-Bay for about $300 (including shipping from China), but mine has already gone through the burn-in period and you can get it for more than $100 less. I will ship it in its original box. Remember, I pay shipping for my asking price. This preamp sounds much better than its low price would seem to idicate. Check out its specs on internet sites.
