Integrated Amplifier Recommendations Needed

JBL L112 should get vintage Sansui. An AU-9500 or AU-6600. A 9500 can be found under $2K and a 6600 less than $1K. Those two would be epic,... just my opinion. 

Echo Audio has a Primare i32 integrated with the add on streamer that would be great for your situation. I believe it’s about $1495 so well under your budget. 120 wpc.(no, I don’t work for them, I just saw it on their website earlier today)

If you can find an Audiomat of any kind I would grab it.  I have owned an Audiomat Arpege integrated tube amplifier for more than 25 years and an Audiomat Prelude Reference MKII for over 20 years.  They each have had only one Repair and it was to the volume knob, an inexpensive Repair.  If you read reviews they tend to be glowing.  Audiomat is not particularly well known in the US which is most unfortunate because it performs well above its price point, is attractive and sounds exceptionally good.

" My point is specs can be very misleading which means a demo is almost a necessity when unsure about amp/speaker synergy."

How does one do that when buying used? Just curious.

I used that Belles driving my easy load Harbeth HL5s and it came damn close to my tube separates. It is an old school integrated without all the bells and whistles. A think it would be perfect match with those vintage JBLs!!

Gato dia 400s i have had hegel, musical fidelity, cello but the gato price quality is top.
