Not to detract too much from your post, I just noticed you have a Rega Elex-R amp.
If you don't mind, please describe this amp.
I'm now thinking of upgrading one of my amp, since I'm now refurbishing one of my favourite speaker, AR-91
This AR like some of them, are a bit demanding on certain amps. Not only that, I'll also be able to use it with my other speakers, including the KEF.
I'm now saving, and some of the amps I'm now looking at,
Rega Elex-R, Elicit-R, Simaudio 340i, Naim nait 5si, nait xs2, also, maybe some used Bryston
I don't have a lot of experience with solid state amps, and have never heard a Brio-R, for what it's worth.
That said, I absolutely love the sound of this amp. It has a depth and dimension that I've never heard in a solid state amp. Actually throws a wider soundstage than my TAD-60. I can imagine that I may phase the tube amp out of my system completely, though I'm not in a big hurry to do so.
However, my experience with Rega's US service has been really disappointing:
It's kind of along story, but my Elex-R came to me as a gift. It had been sitting unused in a corner of a wealthy audiophile's home. It had been used a total of maybe an hour when I got it. Absolutely dead mint, and the remote hadn't even been unwrapped. And it was hand-delivered to me, so it didn't have to endure any rough handling from a shipping company.
But shortly after the Elex-R made its way to my home, the volume control starting causing problems. I checked in with The Sound Organisation in Dallas, US distributors for Rega. They were very polite, but insisted that since I wasn't the original owner, it would be "inappropriate" for them to cover the cost of a repair. Instead, they referred me to their sole authorized repair tech in the U.S., who happens to be quite far away (California). While he was also polite, he did recommend that I pre-authorize him to spend $350 on the repair, warning me that the bill could be higher than that. Shipping in each direction would be on top of the $350.
Living in a city with many pro audio techs, I instead went to a friend (lifetime audio tech) who confirmed my own diagnosis that it was simply a faulty volume pot. So again I contacted The Sound Organisation in order to obtain a spare. Turns out there wasn't a single one to be had in the US, but the Service Manager told me they had a shipment about to be sent from England, and he'd have them include an Elex-R volume pot in the shipment.
The bill for one motorized Alps volume pot, which physically at least looks like several offered by Parts Express, etc. for less than $20? $66.00. The Sound Organization then charged my card another $18 for UPS ground shipping from Texas to Tennessee.
So while I do love the Rega amp, it would be unlikely that I get another of their products (speaking as a guy who normally buys used). Clearly, they're calibrated to honor the letter of their warranty rather than the spirit.
Maybe more of an answer than you were hoping for, but at some point I figured this story was worth sharing.
And if anyone reading this has ties to either Rega or The Sound Organization, by all means please feel free to share the link to this thread. If I'd really wanted to make a huge deal, I would have started a product support horror-story thread weeks ago here and on other boards. That wasn't (and isn't) my goal. But Ive finally decided I'm not going to give an opinion to a potential Rega purchaser without mentioning this.
