Under 1500$ Solid State Amp for Usher Be-718

I used to have BE-718..but didn't really like the bass. At least 200wpc for the spkrs to perform the best...imho

Noticed there's a nice McCormack DNA-1 Rev A available now for $1400 that might pair nice with the be-718s. Best of luck.

How about Usher R- 1.5 Power Amp for
tube like presentation and good midrange
and Bass.

There's only one way to get a tube like presentation and that's with tubes. Some solid state amps, such as the Usher, are a but warmer in comparison to other solid state counterparts. The biggest difference in in harmonics where solid state cannot give you the same 'tone' as tubes.

The Usher amp is very smooth with excellent dynamic control. One of many good options.

The Redgum RGi120 enr on eBay right now would be a great piece if the auction stays in your budget. Best damn solid state I've heard.

Full disclosure: its mine.
