ARC Ref 6 and Ref 10 opinions , talk, stories, buying options and opinions


Just for fun question. One of my thoughts from all you audophiles who own the Ref 6 or Ref 10 or anything below would like to know if you had a choice to buy a brand new Ref 6 or a used Ref 10 which would you go with. And i would love to hear your opinions on both of these preamps.

If you could get a demo of the Ref 6 to make sure it’s for you, then that’s a different story. Friends have owned the Ref 6, in some cases twice, and moved on. I had a Ref 6 and I personally was not happy with it. I now own a Ref 10 and can not believe how amazing it sounds. The Ref 10 sounds so much more relaxed, smooth, has a wonderful pace, rhythm and timing that I never had from the Ref 6. The Ref 6 can be impressive at first but gets tiring over time when you realize the bit of aggressiveness on top.

So, a used Ref 10 in good/great shape over a brand spanking new Ref 6.
This from a gentleman who just three years ago got on this Board and asked for opinions as to the relative SQ of the GS150 vs.the Ref 150SE (they are functionally identical) and asking how hard it is to bias the Ref 150SE (about as hard as removing a bunch of screws to get the top off and then using a Fluke). Forgive me if I don't find you very authoritative about ARC gear. I've owned ARC gear for over a dozen years. The Ref 6 is the newer design but there is no getting around the fact that the Ref 10's separate power supply is going to provide sonic benefits by isolating the transformers from the sensitive output circuits. So yes, one should expect that a used Ref 10 if in good shape is going to sound slightly more detailed and relaxed than a Ref 6 but the Ref 6 is among the very top preamps existing on this planet. Mikey Fremer may not be perfect but he does have good ears and read his review of the Ref 6. It's a rave in every regard. Then audition one. The Ref 6 takes 400 hours for it's huge amount of capacitors, many of them quite large for a preamp, to burn-in. It is also extremely sensitive to cabling. I never found it "aggressive on top" but using Cardas Clear Beyond between my Ref6 and Ref 150SE made a huge positive difference over many other XLR's I tried. You can't go wrong either way. I would also recommend that anyone spending the price of admission for either invest in a good equipment rack. I upgraded from a typical mdf and rebar rack to a Symposium Osiris Ultimate and it was (IMO naturally) money well-spent. 
I’m only giving my opinion, never claimed to be an authority. That’s great you love the Ref 6. It’s not for me or for friends of mine who have owned them. I’m a Conrad-Johnson fan but love the GSPre, Ref 10 and GS150. I’m sorry if I hurt your feelings with “my” opinion.

I have heard both the REF 6 and REF 10.

I own a REF 6 and would no hesitation purchase a REF 10 if budget allowed.

The REF 6 does everything quite well.  If friends asked me, depending on what their budget was, I would tell them to take either a retubed REF 3, REF 5SE or REF 6 and if their system called for it and budget allowed, a REF 10.

The REF 10 is the best pre-amp I've heard and I've heard some amazing pre-amps.

Matched with REF 250SE or 750SE amps, and that part of the system will basically disappear sonically.

As I've mentioned in other posts, when you get to this level, you really aren't missing much and jaw dropping differences really don't happen.  Subtle sonic differences and nuances maybe. 

The real test is to A/B listen in your home system with a REF 6 and REF 10.  If that can't happen, then an A/B comparison in a store's system with a REF 6 and REF 10.  Changing nothing else but the pre-amp.

Another thing that I believe people do incorrectly when comparing equipment is that they don't make volume levels.

An apple to apples comparison would entail listening a the level you desire on device A, then place a test CD on at the same level and measure with a db sound level meter the db level.  Then, when satisfied, remove device A and insert device B and play the test tone and adjust the volume until it matched the first.  Then, listen to the same music.

I believe that many people perceive differences in sonics as superior/inferior when actually it is volume/gain levels that are the only difference.  I hear things like, the highs are more pronounced.  or the bass is lower.  But, my first question is, did you match volume levels first?

Anyway, if you have the system, budget and money, the REF 10 is simply great.  The REF 6 is high end great also.  Brand new, full retail, they both are stupidly expensive.  But, on the used market?  you can find really good value.
