The audio research arc line- from top to bottom.

In addition to what MoFi mentioned about the short time I had with the REF3 I will add that my LS-26 did improve performance with the 6H30-DR tubes from BAT. These have brought the LS-26 to it's peak performance. However even at the peak performance the LS-26 is still not a REF3. And as mentioned as well the 5 exceeeds the 3 in every dimension. So based upon personnal experience to answer your question, a firm no, the 26 doesn't out perform the 3.
And with all the extra circuitry in the 3 compared to the 26 it is my understanding that most of it is dedicated to the power supply. It seems contradictory that more circuitry is required to make itself disappear from the signal path. Oh and your welcome Brad.

Agree with everything that has been said. I owned the LS-26 before upgrading to the Ref3. The LS-26 is a great amp and probably the best value in the ARC preamp line but the Ref3 betters it by a considerable margin. And now with many used Ref3s avail (because of the launch of the Ref5) I would go for a Ref3. The only other thing I would mention is the new SP17 which probably equals the LS-17 but also has a phono stage incl in case that interests you. Tone Audio recently reviewed it favorably.

Guys:

The stock ARC tubes in my LS-26 now have around 2500 hours. A few questions for LS-26 owners:

These tubes are rated to 5000 hours--will they really go that far or should I consider replacing them soon? The unit sounds as good as the day I bought it FWIW.

When I get to replacing them I'd be interested in going with an upgraded set of tubes to get the most out of my preamp.

Can you tell us about your experience going from the standard 6H30's to the tubes you got from BAT, which they are calling the 6H30P on the website not the 6H30-DR? In what ways and to what degree did the sound improve? How much did these cost compared to the stock tubes?

Thanks for your help with this.

Also, I've never heard anyone claim the LS-26 is superior to the REF 3 and wouldn't expect it to be at their relative price points. While I have never heard the REF 3 I can say that the LS-26 is a very fine linestage. Not only does it sound incredible but it is solidly built and ergonomically well designed. A really beautiful piece of gear that I will keep for a long while.

I have read that the 6H30 tube will actually last around 10,000 hours. I know that ARC says 5000, but I think that ARC wants owners to always have the best sound, so they recommend a replacement more often.

The "DR" version of the 6H30 gives me more depth and width to the soundstage, better bass control, with a smidgen more deep bass. It also gives a better definition to the highs, with a smoother midrange.

I know at one time BAT only used the "DR" version, but I think that supply might be gone. The 6H30 tubes that I have seen come as a 6H30P, a 6H30P-I and the 6H30P-DR. The normal 6H30 tubes are around $30-$60 and the "DR" tube are anywhere from $160 to $400. I have also read that pre 1983 or so "DR" tubes are the ones to buy.

You might give Viktor at BAT a call or e-mail and ask him for sure.

BAT no longer includes the DR tubes in their products, even the REX pre-amp, but you can buy those tubes from BAT.......at the going market price....
