$510.00 for an Aluminum cover for the ARC Ref. 10?

I've been pondering a pair of Audio Research Ref 610T tube amplifiers. $45k when new, can now be had for $14k. I've been thinking long and hard about acquiring a pair, but the specter of the $4K cost to re-tube haunts me. If I pull the trigger on a pair, I know that EVERYTHING associated with maintenance and repair will be expensive. Even the shipping back and forth to the factory will be expensive.

ARC figures that if you could afford a $30k preamp, to ding you $500 for a lid, you probably wouldn't notice.

Markwatkiss, I've owned several BMW's...and still own one. And I do know that when you buy one, you sign up for the insane maintenance costs that go along with it. I've done that since 1984 and wouldn't have it any other way. After more than 30 years of BMW's, I've been conditioned to expect costly maintenance.

You, buy a $30k preamp, the mfg and dealer expect you to know what league you're playing in and not to wince when presented with any type of bill. Dorothy, you're not in Kansas anymore.
