My NAD 326/545 combo now does service in my study, whilst my CA 650A/650C combo with B&W 685 is in the main listening room. I am pleased with this set up, but wonder if there's any point in upgrading to the tune of £1500 +/- a few hundred? Apart from the engaging sound of my CA set up, I like the 'one for all' remote and it's features, and would want the same sort of arrangement with an upgrade. Obviously I've looked at the reviews etc., but wondered what recommendations you would make? I listen to all sorts of music, but mainly classical,and jazz/blues. I like faithful reproduction........hey isn't that what high fidelity means?
