Got a pair of NuForce Reference 18 mono blocks. They’ve been upgraded by Bob Smith (TDSS) in April 2018.
They are excellent, and control my current hungry speakers expertly with exceptional detail throughout. If you have a great source and really want to hear just how good it is, then this is the equipment to do it.
Rated at 175/335/355 watts into 8/4/2 ohms and will do 325/650/1200 watts respectively.
I have a pair of these with the same upgrade, and they are great! A terrific price for whomever might want them. The most underrated amps in the world, IMHO.
Just putting in my 2 pence. Note that TDSS recommends that when you don’t use them for a long while, such as at night, turn them off. Good advice to me whose previous experience is that transistor amps need infinite warmup times–these don’t and should not.
