A really great sounding inexpensive integrated is a Tandberg TIA3012. It’ll set you back $300-350 and is heavily biased into class A as it runs very warm to the touch. I had one for a few years and loved it. Kept it on all the time with about 4-5” of ventilation on top. 100 wpc, MOSFET outputs, very warm and tubey sounding. I would take one anyway over NAD or many others mentioned. Only sold it to go to separates.
