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.

Very good suggestions made here. I’m driving mine with an MC275 and I’m very content, however for you I’m recommending the most recent Peach tree model I believe it’s the 500. 
I’m driving my SHL5+ 40th with a VAC 160i. I run a REL T7i crossed at 45 just loud enough to not know it’s on but more of a feel thing for the lowest octaves. I’m tempted to try a Luxman 509x but the VAC is just sublime. 
@rcalderon I am currently running mine with 2 MC275s.  I initially started with only 1 but felt like it was running out of gas on certain types of music.  I still feel that way now with 2 of them.  Do you feel that 1 is enough?  I still feel that my Pass XA-30.8 was by far the best.  I am very tempted to get another, but I don't want to lose a ton of money on the MC275s.
I'm using Naim pre/power on my Super HL5 Plus.

Don't skimp on the source/DAC as I find it equally important.
