Straight line stage integrated amps (w/ no DAC or phono) are pretty uncommon these days, and why pay for something you don't want or need. Going on the used market would up your options. Class D is better now than it was, some people like it and I wouldnt rule it out as an option in that price range. If you want a compact class AB unit with a linear power supply, maybe look for an older used Bryston B60, it's one that has no dac or phono stage. I had one a long time ago that I got new from Canadian dealer for $1100, they go for 3K now. It's has a neutral tonal balance, very clean and good detail, which seems to be a sound youre looking for.
