used power amp under 1500

Van Alstine SET 400 will fit the bill and they are available for under your limit like here:

@devinplombier the ARC DS225 is likely to be sonically superior to most of the options discussed here. Yes it’s a 15 year old class D amp made by Audio Research. Not sure if you skimmed thru some of the suggestions here. 
In any case, this isn’t worth an argument since OP has been waffling and will most likely continue to do so for a foreseeable future.

Not to belabor the point, but here's the JVS review's bottom line in Sterophile:

Was I impressed?
I was. Replacing class-AB amps that cost many times more, surrounded by comparably high-end equipment, the ELAC Alchemy DPA-2 Switchable Stereo/Mono Power Amplifier delivered far more musical truth and pleasure than you might expect. Chief designer Peter Madnick has exceeded his goal "to provide the kind of real-life transparency and clarity that you would not expect at this price point, as well as an overall balance that would lead you to say, 'Wow, that thing's really good for the money.'" He may also have created a benchmark product for this price range—not that I've heard all the monoblocks that are available for under $3000/ pair. (There aren't that many.) But if there are many other equally fine amps at this price, budget-conscious audiophiles are living in a golden age. Enthusiastically recommended

since OP has been waffling

you can call it that. But I bought 2 class D amps, tried them, sent them back, made offers on several amps, and currently testing one. 

@parkergetdean cool! Glad to hear you’re making progress! 

Not all Class D are the same. Heard a really nice pair of Atmasphere mono amps at a NY Audio Show powering Audience speakers. Fantastic sound!
