Audio Research Ref 5 preamp

Micro, what was the change contributed by the ref5 before you moved to a new rack? I wonder if the rack then should be mated to the the REF5 to further improve it?

I bought the Pagode rack some years ago when I still had the Ref3 and CD7. I had an old Target that was solid and had a special decoupled upper shelf for the turntable that I used for the CD7, but I was astonished with difference when I moved the system - everything become more solid and bass become quicker, voices were more defined and articulate, becoming more dramatic. After a few months I returned to the old rack to try another system in the Pagode and it was a big step back - some parts of the music seemed blurred.

I had the Ref 3 and compared it side by side with the MBL 6010D which I kept and I sold the Ref. When I moved from tube to Spectron power amps, the Ref 3 was not a good match and the MBL was much better. Not a question of the Ref 3 being inferior, but I suspect the impedance made the difference and the MBL was more natural and controlled proving yet again the importance of system synergy in the real world.

While I am very impressed with the 6010, I would like to try the Ref 5, but not with my Spectrons. In the appropriately matched system the Ref preamps are as good as it gets and I am sure the Ref 5 will offer state of the art performance for a 'reasonable' high end price and quality dealer back up. If you like the ARC house sound, which has a definable character, I am not sure I would need to go from a 3 to a 5 as I am sure the changes are incremental.

Probably around this time replacement of 610T (to match up Ref.5) is already lurking on the horizon somewhere at ARC.. Anybody anything yet? Anyone remembered the time lapse in between release of Ref.3 and 610T? Would be great if ARC could improve their line of Reference amps in similar fashion and magnitude as they did with the pre.

Interesting question. I am happy with my REF210s however maybe there are silver handles on the horizon as one of the upgrades. A little beefier fan/cooling configuration would be a nice upgrade. Circuit boards are already horizontal, so no upgrade there...
