Class A can be expensive, especially if you are looking for 200 wpc. In the ~$3K range, you are probably limited to older amps like the Krell KSA-250, Plinius SA-250 mk IV, CODA System 200, Threshold SA/12e or T800. Though these would probably need to be re-capped, if not already done.
Newer options such as Pass Labs, Clayton Audio, etc., would be well above your $3K price point. I would think that if you need that much power, 200 wpc, you would be better served by buying a Class A-A/B designed amp that may run rich in Class A, maybe up to about 25-50 wpc in Class A before sliding into Class A/B.
