Audio Research REF 6 to REF 6SE upgrade.


UPDATE””””””””” I just got off the phone with Audio Research about the REF 6 to 6SE upgrade and I was told that the price of the upgrade went up from last year from $3500 to $5000. I was pretty shocked. Also he said that it will not have to be done by the service dept as they have a guy who strictly does Ref 6 upgrades. as all parts are in stock and it will only take 14 days turn around time.

@brunomarcs   Also I am sure that I would be very happy with the upgrade. This is definitely my top of the line pre amp that I will be going with them. I will not be upgrading it again being a Ref 7 or a 10. Same as my Ref 750s. Those are here to stay for good.

Hopefully you have good air conditioning, those amps will generate a lot of heat. I bought a krell amp from a guy that was using the audio research 610T amps with the kt120 upgrade, and he had to figure in a bigger central air unit. He was using those amps just to power the midrange/tweeter and a pair of krell fpb 750 mcx for the bass. It sounded really good with the apogee divas.

@invalid   Yes. As a matter of fact I’m installing a brand new Mitsubishi 18k btu split system AC unit. Also these REF 750 amps are also upgraded to the KT150s from the KT120. So I am sure there will be good heat from them. My Krell FPB 600 put out a lot of heat and I’m sure these would be more.
