Downsizing from Audio Research REF110 to 100.2

Thanks everybody for the answers, I think I have to try to see what happens in my system. If I do I will post my experience in this thread.
I am sure REF110 is a superb power amp but I also feel I am not getting 100% of its possibilities, perhaps there's a problem in my room, of I would need a better (and maybe bigger speakers). I heard that Proac is a good match with Audio Research but not sure about current models...

I am not closed only to ARC but I have not experienced with other brands, I used a D200 with good impresions, specially in bass response, so I think the 100.2 could be a good amp to try.

I feel in general a lack of air, the bass is not as defined and sweet as I wanted. Audphile1, maybe you are righ with the Proac remark, with some records the system is a bit aggresive also.
In general I believe the system should sound better having a REF3 and REF110, if the problem is with the room it has no sense to maintain a REF110 working at 50%.

Anyway I have to recognize that I have a very natural mids with good recordings, the realism in some cases is very impresive, but with a poor average of such recordings.

Thank you again for your help.

I have a Michell Gyrodec + Origin live silver tonearm + Ortofon Jubilee + Graham Slee Era Gold mk5 + Graham Slee Elevator EXP as a phono preamp's.
My CD is an old Linn Karik + Numerik modified with bybee filters.

I don't think the problem is in the source because both have the same character and defects when listening through the speakers, otherwise the listening with headphones (Graham Slee Solo + Sennhesiser HD600) is very satisfied.

This is why I think the problem could be located in the trio power amp-speakers-room.

Audphile1, the REF 3 is completely broken with more than 1500 hours and the REF110 has about 450.
I had the Audio Research D200 with Ruark Equinox speakers and Linn Kairn preamp, I had also the Ruark Equimox with the REF3 and VT100 MKIII, and I had similar problems than I am having now, but with a bit less global performance.

Maybe you are right that with the D200 the sound was more forgiving, I am not sure if too much resolution could be a problem for me.

After almost 3 years I thing all of you deserve a response.

Some months later I bought an ARC 100.2 and I tried in my system for several weeks, almost all of you were right, the REF110 is much better than the 100.2, specially because it is closer to the real music. Only the bass was tight and with more punch in the 100.2, but the emotion of vocals and highs with the REF110 was missing in the 100.2.
This does not mean the 100.2 is a bad amplifier, I thing the majority of audiophiles could live with it.
It is curious that I sold the 100.2 to the same person who I bought it because he missed it after trying other amps.

Then I discover that the fault in my system had to do with the speakers (Proac D38), or rather with the isolation with the floor (which is made of marble). I bought some RDC cones and a methacrylate platform which improved the bass response with a overall improvement, only was introduced a bit resonance in mids frequencies.

After a couple of years with a satisfactory setup I want to explore a bit the possibilities with isolation and room condition. I will create another post for that.

Many thanks everybody.
