I've used a Graham Slee 2 special edition for several years now. It work's fine with Denon's high output mc cartridges. I have the 160 which is listed at 1.6mv. Over all the Slee pre-amp does very fine by me. No idea what other, greater, more expensive pre-amps would do to give me a finer appreciation for my music. Other than DIY I don't have the money or inclination to find out what similar or higher end units can do. The Slee is over priced enough as it is.
