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

You might want to also consider a Plinius integrated amp as you had stated above. They make excellent products. I have owned several of their integrated amps and regular amps over the years. They are built extremely solid and have great sonics. I'm currently using the Plinius Reference SA amp in my main system and love it.
The Harman/Kardon 990 amp has gotten very good reviews and has a terrific amp section (VERY high current capability), can handle up to 2 subwoofers, plus it has room correction capabilities - very sweet! And it's $1995 brand new. Definitely check this one out...

If you are not opposed to Tubes you might want to try an ARC VSi-60. At the moment there are a couple for sale here on this site; no affiliation.
Another great SS Integrated although you would have to bump up your budget a bit(used) is the Pass INT 150 or 30A. Reno Hi-Fi offers a free 10 day in home trial all you pay is shipping to and fro if you send it back.
