Audio Research Ref 6 vs 6SE

Would like to learn about the difference between ARC Ref 6 and 6 SE. Information in the web said that 6 SE involves upgrading 18 capacitors and 14 runs of wiring. And, owners of ARC Ref 6 can upgrade it to 6SE at a cost of $3,000.
How far is the actual difference in listening? Does it worth the money to upgrade? Would dealers in different parts of the world able to do the upgrade which seems to be done on site?

ARC updates such as this are usually done only at the factory.

If you want to hear the difference for yourself, you could take your Ref 6 to your dealer and do an A/B comparison with his Ref6SE.

I upgraded from the ARC REF 5SE to the REF 6SE so I cannot speak from direct experience. Is it worth it? I have read most everything in print on the subject. If your system is at this caliber… then absolutely the sound quality change is substantial. Also, you have a world class preamp… the upgrade helps maintain its value and will sound better. There is another forum, audio aficionado, where many members own this pre amplifier and systems at this level. There are a number of threads on the subject.



Yes, it is done at factory only. This is also something you want to do while offered.
