Audiodesksysteme Gläss Pro Vinyl Cleaner ($4199)
Without playing a note, the Audiodesksysteme Gläss Pro Vinyl Cleaner rocked my listening world. This wonderfully designed car wash for LPs accomplishes far more than I expected: reduction in noises of all kinds, and a magical lifting of yet another veil from the music. Brilliant!—Sasha Matson

There were a few glitches, mainly logistical: Shipments didn't arrive or arrived damaged. One exhibitor had to carry an integrated amp to the show on his lap, first on a bus and then on a plane. (I didn't think to ask: Did the amplifier fit in the overhead bin…

Analogplanet.com covered new products exhibited at the 2012 Rocky Mountain Audio Fest in Denver last October (Stereophile's full coverage can be found here); in this month's column I'll comment on the show generally, and specifically on two seminars.

Nick Doshi, accompanied by Jessie Bentley of Virginia dealer Command Performance AV, picked up the Doshi Evolution Stereo amplifier from Ken Micallef's Greenwich Village apartment and delivered it to me in Brooklyn. They carefully installed the eight numbered Electro-Harmonix 6CA7-EH output tubes, then Nick briefed me on his design philosophy and how to operate the various buttons and switches. As I did with the similar-looking Evolution Monoblock amplifier that Jason Victor Serinus reviewed in May 2021, I left the amplifier powered up for 45 minutes before I…

Since I purchased the review sample, along with a lifetime subscription to Roon, the Roon Labs Nucleus+ music server ($2559) has been my primary source for digital music. I have been using it with network-connected D/A processors that can act as a Roon endpoint, like the PS Audio DirectStream and MBL N31. I am currently without a NAS drive, so Roon accesses my music library via an internal drive I…

The Convergent Audio Technology SL-1 Signature preamp was Stereophile's Product of the Year in 1993. Now, 23 years later, when I consider possible candidates for this honor, I can't think of a better choice than the latest version of the SL-1. How's that for longevity?—Robert Deutsch

Yes, there are many speakers that offer greater bass extension, dynamic range, and imaging precision, but at prices that range from five to 500 times as expensive as the Alpha P5.…
