Integrated Amplifier Recommendations Needed

PrimaLuna EVO 100 Award winning great sounding 40 watt tube ampifier will make your JBL’s sing. Cool looking too. Solid build quality. Some pre-owned on this site for under $1900.

I am a big fan of some Denon models, such as the PMA A110. Not so much of the new Yamaha. Peachtree has free trials, in your price range.

Used Rogue Audio Cronus Magnum II's go for around 2 grand.

+1 for Parasound.  I recently upgraded my TV/family room system with a lightly used Parasound Halo integrated purchased here on a-gon under $1500.  I have an older pair of PSB Synchrony Ones in a very large room and the change has made a significant impact on the overall sound.  It is a tough room acoustically speaking, yet the improvement was immediately noticeable.  Greater bass impact and articulation and a seamless soundstage that extends beyond the width of the speakers.  I’ve only had it for two weeks but I am delighted.  

The Halo is a full featured integrated with a pretty decent DAC, MM/MC phono section and a balance control.  

Though I currently have only one, I plan to upgrade to a pair of subs in the future and the Halo can accommodate that with an excellent circuit that provides a high pass filter and it has a front panel control for subwoofer output as well.  

A new Parasound HINT 6 runs $4k but a used Halo integrated can be had for less than two grand.  There may be some better sounding tube or solid state amps out there, but the Halo is a solid all-around performer with a smart feature set making it an excellent value.  

The Yamaha A-S2100 recommended by @helomech is a solid candidate. The Yamaha integrated has a very quiet and excellent phono stage if you run a turntable. No built in DAC if you want/need that feature.
