Audio Research REF 6 to REF 6SE upgrade.

@tattooedtrackman I meant that I wouldn't be sending in my ref 6 which I don't even own yet, and paying the price to upgrade it to the ref 6se. Which we now know is 5,000. Once you get the work done you'll more than likely be very happy.  They probably do more than just the capacitors and wiring!  
 

I suspect if one was to do the work themselves or sub it out and one day there's a problem with a proprietary piece and youd have to send it in to arc, they'd probably decline to repair it? idk for certain just an assumption!  I would like to know this! 

@brunomarcs   I totally think that it void the warranty if u have other services done on any equipment other than Audio Research. It just makes common sense. 

@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.
