Harbeth Super HL5 Plus speakers & integrated amp pairing recommendations


I'm seeking suggestions for an integrated amp to match with a pair of Harbeth Super HL5 Plus speakers that I recently acquired. I listen to mostly smooth jazz via streaming or CDs, no vinyl.  My listening room measures 22' x 22' with 11' ceilings.  I welcome your recommendations for integrated amps.  Thank you.

Up to $8000.00 for the budget.  Open to both solid state and tube choices.  Thank you.
I like @jackd suggestion. I'm using a Accuphase E600. It works for me well in my small listening room with a REL B3 sub. The E600 was expensive but I got a deal on a demo which is why I own it and I love it but at full retain it's too much money (maybe).
