Audio Research REF 3 and REF 5 Tweaks


Hi,
I was wondering what tweaks have been used successfully with these two preamps? I'm thinking specifically of footers, weights, tube dampers, powercords, etc. I haven't considered tube rolling as from what I've read, the tubes ARC recommends are probably overall the best.

I've tried several products including Vibrapods/Vibracones, and various isolation products from Herbies on my REF 3 with mixed results. (I keep going back to stock.) So far the best tweak has been to purchase and place Herbies Ultrasonic Tube dampers on the two power tubes, the 6550 and the 6h30, in the powersupply. Strangely ARC does not include dampers for these two tubes but the addition of Herbies tube dampers really cleans things up.
I use Solidsteal shelving which have been damped with sand.
So what have you all tried that you think would be a worth whild audition?
Thanks in advance,
Sgr

Yes it is $250.I just bought one for my 5se and now that i sold it i will be selling my brand new clear cover. BTW you cant get a piece of cardboard from ARC for $25. 
I too have not heard a difference in sound with the display off. As for the covers being left off ARC told on the phone when i ordered my 5se clear cover its best to leave the cover on for sound performance and tube vibration. 
My Brand new black ARC Ref 6 came in the other day and to my big surprise was the new twice as thick plexiglass cover that comes with the new 6s now. The front and 2 sides are beveled to making it very attractive also. It came with the smoked plexiglass with black screws prob because i bought the black 6. It will prob come with the clear cover if bought the natural silver finish. Anyway there is no way this new thick cover will dip from the heat.
