You can get an Ashdown RM-500 within that budget, worth checking out. I have one as my practice & backup amp and it’s a very good, powerful amp, with a great sound and very flexible eq. Probably the fullest sounding small Class D amp that I’ve used, and I’ve had many (Aguilar, Markbass, Ampeg, GK, TC Electronic). They were all good but the RM just had a depth to the sound that I found the others didn’t.
