I’ve had one good experience and one not-so-good experience with Upscale Audio.
The good: A few years ago I called looking for advice on a sub-$1,000 turntable. The associate recommended a Rega P2 (about $775 at the time) and suggested upgrading to a Hana high-output moving-coil cartridge. When it arrived, it was obvious they’d taken the time to set everything up (tracking force, alignment, etc.), included clear instructions, and even added a handwritten note explaining what to do first and to call with any questions.
The bad: A little over a year ago I bought an Sbooster linear power supply for an older Bluesound Node, only to discover it wasn’t compatible. I emailed to confirm, then called to discuss alternatives, including selling the older Node for a newer compatible model or moving to something like a Cambridge Audio CXN. I ultimately decided to hold off and returned the Sbooster for a refund.
UPS showed it had been delivered, but after a couple of weeks I realized the credit still hadn’t appeared on my card. I called, they apologized, said there had been a mix-up, and processed the refund immediately, which I appreciated. Still, I didn’t love having to remember to follow up on what should have been a routine refund.
Overall, I’d say my experience was one very good transaction and one that ended fine, but only after I had to prompt them. And I still enjoy Kevin Deal’s passionate YouTube videos.
