ARC REF 750


Well I finally pulled the big trigger , I just purchased an Audio Research REF750. After many years loving and enjoying my Krell FPB 600 i got tired of all that booming bass and now missing the musical clarity that I know want. Don’t get me wrong I still love that big beast of an amp. It never gave me one problem. It works and always worked flawlessly. I also think that my ARC Ref 6 will be a really good match for the REF 750. Now I’m really thinking about that 6 to 6SE upgrade from ARC. Can’t wait til they arrive.Also use a Rega ISIS CDP and B&W 801 Matrix speakers

I have both the Ref 150 SE and Ref 80S with a Ref 6. The two amps have a very similar presentation. They both need a TON of break-in. 500-800 hours. I was a bit let down by the brand new Ref 80S at first. I was not patient enough. I can't prove this but I believe it is not just hours but also how many times it has been cycled on and off that accomplishes complete burn-in. ARC says many hours are needed in the manuals. 

I am sure you know this but the quality of the IC's between your Ref 6 and amps will be crucial. I prefer Cardas Clear Beyond XLR's. Again, ARC emphasizes the quality of the IC's in the manual. 

@fsonicsmith1 Hi. The ARC REF 750 is not brand new. It’s 7 years old so it is burned in. As far as all my ICs.they are Straight Wire Crescendos. Speaker cables are Straight wire Crescendo. Power cords for amps are Shunyata King cobra CX. Preamp 6 is Straight wire Signa HC power cord. Rega ISIS is Straight wire Sigma digital. 👍
