So I just bought a Hegel H390 and

I've driven the usher be20dmd, persona 7f, kanta 3, VA strauss, salon 1 and salon 2 and currently the Kef Blades and the only speakers the H360 couldn't manage were the salon 2. Unless I can score a H590 I'm set.

I’ve had the H390 for 12mths.
Can not fault it for the price. 
Have run:
LS50’s, Maggie LRS. Klipsch Cornwall IV’s, RP600’s, Martin Logan SL’s, GoldenEar One.R’s, Goldenear Aon3’s.

The LS50’s were remarkable. The metas must be fantastic however your room is a little on the large size for such small drivers. 
You wont be cranking it up, they start distorting 90-95dB on the H390. 

Maggie LRS resolution and soundstage was exhilerating but again too small for your room. 3.7i or higher is better for you. 

The Klipsch Cornwalls; we took out 10K of Cary Audio DAC & Tube amp and slotted the H390 in. 
Expectation was to hear significant drop in overall quality. We were wrong. 
It was still very good, not bright as expected. Nice and neutral if not slightly warm. Could listen to it all day. 

RP600’s, lol. Just for fun. The little $370 speakers did sound like $1000 speakers. But cost $6000 to do so haha. 

M/L SL’s decent but didn’t have enough time to set them up properly.

One.R’s; holy crap could these get loud and not drop a milisecond of speed. Sounded incredible but some may find it bright if sitting closer than 10ft. Resolution is off the charts. Really great speakers. In your room with treatment they would excel if you like to turn it up some. 

Aon3’s… see RP600’s

I like to crank it on Fridays (scotch!) and critical listen on weekdays.
In your room I’d lean toward The One.R’s or Maggie 3.7i w/ a couple Rel’s. 

Just my 2c. 

For the past five years or so, I have had a Hegel H-300 and Sonus Faber Olympica 3 speakers. I really love the way they sound together--including at high volumes. (I listen exclusively to flac files, usually ripped from cds, but higher-res when that’s available. My speaker cable is Nordost Blue Heaven.)

Great thread 

sorry to to hijack, but what speakers would be good match for Hegel 190? 

Currently have audiovectors which I like but mixing to larger listening room and feel will need something "bigger".

what would be a good upgrade ? Typically listen to rock , alt country etc 

Hi JD. Congratulations on your new Hegel H390. Excellent choice. I had a H360 for a few years in my 2ch system in a room 14'x25'. I enjoyed the H360 for a few years and auditioned the H390 soon after it was released. While I was very pleased and impressed by the H360, the H390 clearly improved on the all of the good qualities and then added a little sweet icing on the cake. The H390 had the same transparency and neutrality that I love about this amp, as well as, the tremendous control of almost any speaker you connect to it. I has the ability to make even lesser speakers shine. That said, I have matched the H390 with a little know speaker from Finland. The manufacturer is Amphion. They make a full line of speakers from mini to full towers are quite popular with recording studio engineers. I model I use as my reference speakers are the Amphion Argon 7L floor standers. They are a superlative match with the amp and are truly something special. I auditioned speakers and amplifiers for two years befo re purchasing the amp and speakers. In fact I tested speaker and amps in the 5k to 100k range and found the price performance of the H390 alone was equal  to or greater than amps costing 3x as much. As for the speakers, the Argon 7L or newer 7LS blew away speakers costing 20-50k that I auditioned at length. BTW, these speakers are well below your price range. If you can swing it, the Krypton 3 is their top of the line speaker and would be even better with this amp. I have no financial interest in Hegel or Amphion. I can highly recommend a dealer that I purchased my equipment from. Adirondack Audio in NY. Happy to help if you have any questions. Best of luck. Audiofool1
