Great recommendations, I think, above. One of the nice things about so many of them is their high quality, robustness and reliability. I would not hesitate to pick up any one of them on the used market, if that was what I could afford, though I am not really familiar with Blue Circle.
My Supratek Cortese LCR is the first piece of equipment I have bought in a long time for which I paid full retail. And I've never had even a particle of buyers remorse. It's always simply been a tremendous source of satisfaction. Sounds great with solid state and also tube power amps.
