Audio Research Ref 110


I have 88 hours on my new Ref 110 and it sounds v shrill, with a somewhat thin midrange. I have heard that this unit takes 300 hours to break in. Will this shrillness go away as part of the break in process?

Thanks guys. The only reason I hesitate to list all components is that over the years in this hobby, I believe I know the character of each component I own and how placement of everything (all on isolation devices), cables- pcs (Shunyata) ics (Stealth Indra), etc. impact the sound. Since I have tested many items and changed the system over the years a number of times--all to work the synergies to my liking, I do not want to run a long thread in which I get numerous suggestions (try this cable, that isolation device, move the speakers)--all of which have been done too numerous times to mention prior to getting this amp and a few times after. So, with that in mind, I wanted to know if this trait was part of the break in process so I don't go crazy making adjustments and then find that the amp will become more relaxed and less shrill on these items over time causing me to readjust. As this is the only change in my system in the past year and I have had other amps that did not exhibit these traits including most recently the McIntosh MC2102 (which is smoother and rounder but less neutral and transparent than the REF 110), the first question is-did my past amps mask some thinness in the average cd and badly recorded records that the REF 110 reveals such that I am now hearing it. I believe this to be the case. Now as for the new found issue, will this character be somewhat ameliorated by the mere passage of time with the REF 110? I believe from Mickey sg' response that I must wait about 300 hours to pass judgment. Rest assured if the problem does not go away, I will be back with hat in hand and an examination of other components and synergies will ensue. Are there other ARC amp owners who agree with Mickey sg' s opinion?

I can say that compared to the VT 100MKII and VT200MKII combined with my LS25 and Ref2 MKII, the newer Ref designs are more solid state like in their presentation, albeit with increased dimensionality and huge soundstaging. For me, the advent of the 6H30 tube/crcuit has coincided with my recent decrease in interest for ARC, BAT gear...yes, I owned a Ref 3 and sold it. Why? Because it sounded solid state like in tone color and was a bit soft down low and up top.
Mickey sg, looking at your system, it is amazing to me that with the MIRRORS behind your system that any amp through any speakers would sound anything but thin and 'shrill'!
Perhaps locating the whole system in a better location or alternatively damping/covering the mirrors with some kind of major absorbtion would go a long way to helping your problem.
Holy Cats! I aqree with Janeb. With an entire wall of mirrors behind your system, coupled with the tile floors and the large glass coffee table, I'm suprised you're not driven out of the room. Maybe two pairs of Holograms would be the ticket. One pair behind the speakers about a foot away from the mirrors, and another pair behind and on either side of your listening chair would help. I know they transformed my room for the better.

Good luck ...
Hi Oregonpapa and Janeb,

I think some wires got crossed here: I am Mickey, and yes, thats my room with the mirrors, but I'm not the original poster, who was complaining about shrillness. Just for the record, my room doesnt sound bright, as you might suppose. The only thing that suffers is depth of image.

Cheers
Mick
