Can anybody suggest a good preamp that is able to match well with the Onkyo M504 poweramp? I'm looking for one with a remote and doesn't have tubes since I don't want to deal with that. Price-wise 500-1k but if I cant get away with lower than that is fine. Maybe even a Dac/streamer with volume control would fit the bill but not sure. I saw the official sheet that says the input sensitivity is 1v and the input impedance is 20k if that helps.
