OKAY ... full disclosure .. I am an "ARC cheerleader" and proud of it.
On the reliability issue ... I've had an SP6. An SP-14. a Classic 60, a REF-75 and now the REF-75se. I've had all of their phono stages from the PH-3 through to my present PH-8. I've had their CD players from the CD-3 through to my present CD-7se. I used the SP-14 until I upgraded to my present REF-3. I ALWAYS go for the upgrades ... and have never been disappointed with them as the improvements are always significant enough to justify the price of the upgrade.
In all of these years, and with all of this equipment, I've had only one resistor taken out by a failing tube and that was a KT120 in my REF-75. I took it to a fairly local tech who does ARC warrantee work. No problem other than it took a while getting it back.
In the meantime, I had my regular tech go through the Classic 60 and give it a good going over. He replaced the power switch (damaged in the '92 earthquake). He replaced the large capacitors because their measurements were way down. He said that this is normal in old amps. I've owned the CL-60 since the early 80's .. and never a problem what so ever, and the damned thing plays MUSIC! The CL-60 rests under a table in my listening room to be used as a spare. As old as it is, I can't bear to sell it. It just sounds too good.
Other than that one resistor, I have NEVER had a reliability issue with ARC equipment. All I've ever done is replace the tubes when they age. No burn marks on any of my circuit boards either.
I have a reliable source at ARC ... and he told me that they tested the KT-150's for over 5000 hours, on 24/7, with no failures prior to approving them for a replacement in the REF amps that were using KT-120's.
It always amuses me when some guys in these forums knock ARC products. I'm sure they are being very sincere in their assessments. But, here's a question for them ... Should ARC just stop improving their products and call it a day? Or ... should they continue with their R&D and offer upgrades to their customers who are willing to pay for them? Personally, I see nothing nefarious at work here on ARC's part.
