Can't decide on Integrated Amp - Please Help


Hi, really trying to find the best deal I can on a used integrated amp. My current set up is

Monitor Audio RX6 speakers
Oppo 105

Looking for a strong integrated that if I wish to upgrade my speakers will easily handle the change.

Looking at spending no more than $3,000 for a used example and would love some help. I stream most of my music through the Oppo instead of CD's and listen to a lot of Pink Floyd, Dave Matthews, Sting etc

Few choices i have outlined and really hard to be able to audition anything and would like it to match the speakers and Oppo well

Rega Elicit - R
Krell S550i
Hegel 200 or 300 if can afford (is the DAC much better than the 105)
Stello ai500
Saw a PLINIUS HAUTONGA Intergrated A but don't know too much about company.
Modwright 200

My room is around 15 x 15 with wood floors

Thanks in advance for help

Also forgot to mention the amp must be able to connect directly to Oppo XLR so can utilize DAC.
I think you should check out the LSA brand of Amps(Statement). Also Ayon makes a tube Integrated The Triton earlier gens go for a lot better prices used. Both of these can drive your speakers no problem. LSA is a hybrid Tube/SS design, 150/300 watts 8/4 ohm. The Ayon Triton is a ALL tube design with 150 watts stereo. Also, the Oppo will allow use of Single ended cables so It dosent HAVE to be XLR. It will still be utilizing the ESS Saber dacs.
I would put the Ayre up against any of the amps on the market in that range right now. It's a natural sounding amp. It will play what you send through it. Honest. Closest to tubes that I"ve heard for SS and I'm a tube guy. I've heard many of the integrates listed in this thread and many are excellent sounding.
Nothing on your list is a slouch. Just comes down to taste. For me, I'd look at Coda or Ayre.
Good Luck, Tim
I agree with the Ayre recommendation, love mine! It make a very noticeable difference in all areas when I changed to it from my previous Classe Cap 151 integrated.
