ARC Ref 10 tube rolling

The guys at ARC have it pretty well figured out. Tube rolling gets marginal, if any, benefits in the Ref 40 in my experience. I assume  application in the Ref 10 is not much different.

@gpgr4blu  Thanks for the feedback! Cool, so if I ever want tube replacement, the option is from ARC directly? I am a bit concerned that I may need to change the tubes soon due to its hours. Do you know the cost of replacement tubes from ARC? Thanks.

I sometimes get them from ARC but they are almost double the price you will pay at shops like The Tube Depot or the Tube Store which also provide matched pairs, although ARC claims to put the tubes through extreme testing and matching. To the best of my recollection from a few years ago the 6550Cs are about $100 each at ARC and 6H30P are about $50 each there. Hopefully someone on this forum can get you more precise current numbers.

Got it, thanks for the information. @gpgr4blu 

I asked ARC for pricing for a full set of tubes for my Ref 40:  $1,200!  I bought a tightly matched octet + pair of 6H30P's from Upscale Audio (I have a stash of Winged C 6550's for the power supply).  Upscale matches as well as ARC, and the 10 tubes cost me $490.  My 2 cents.
