Hello everyone I am potentially after a small, very simple but very good quality line-stage pre-amp to do nothing other than allow volume control, switching between two sources and then feeding a pair of mono-bloc power amps. I don't need it to do anything else, although a remote control of volume would be very useful (but not essential). Now, before some wag comes along and says that that is what all pre-amps are supposed to do, I will try to explain what I am trying to do: I have a Marantz SR7400 AV receiver with which I am happy for movies. However I also have a MF Tri-Vista DAC with which I want to achieve much better CD replay than is possible via the SR7400. So, I am trying to get hold of a couple of mono-bloc power amps which I want to feed with the output from the Tri-Vista via a very simple but good quality pre-amp. My budget is appx £300 and I am willing to look at second-hand as well as new kit. Thanks.
