Purchased this piece on Audiogon 8 months ago, sent to Mitch Singerman for Level 2 mods at a cost of $400. This is the MM only version. I use and prefer my own SUT with my MC cartridge thus no need for the MC version. In fact, the MM version is more appealing to many EAR enthusiasts. The preamp works and sounds fantastic, only selling because I purchased an 88PB which gives my system only slight improvement over the 834P and the ability to adjust gain. No original box but will safely pack for shipping. Sovtek tubes and will also throw in some extra tubes. Price is fair considering these sell for $1700 new with no mods. My email is firstname.lastname@example.org Shipping and paypal paid by buyer.
