Theta Digital Prometheus monoblock power amplifier

Theta Digital Prometheus monoblock power amplifier

Several seconds after I began listening to it, I knew that Theta Digital's Prometheus monoblock amplifier ($12,000/pair) was different from other amplifiers. The violins and brass were more dynamic, and had more pace. The orchestra sounded more three-dimensional, depicted in relief by a degree of hall ambience I hadn't heard when I played the same recording through my reference solid-state stereo amplifier, a Mark Levinson No.334.

Publisher's Note: For the first time since I've published Stereophile, we are running two completely different—and opposed— reports on the same product. Normally, we try to reach some conclusion as to why reviewers come up with opposite views on a product, and resolve the problem prior to publication. In this case, the problem lies in the differing sound systems used for review. Since some readers will have systems like SWW's, and others will have systems more like JGH's, I felt it was valuable to run both reviews.

For the record, SWW's reference system consists of Dayton Wright XG-lO speakers, BEL 1001 amplifiers, a Klyne preamp, a SOTA Star Sapphire turntable, the Well-Tempered Arm (or Sumiko Arm), and a Talisman S cartridge. The sound on analog disc is far preferable to that from CD, being much more alive and present, and with a tendency to exaggerate sibilants. The low end of the system is awesome, the high end extended, and transients are rendered with a great feeling of immediacy and quickness.

What makes a great singer great is a magical combination of virtuosic physical skills with mental and emotional powers of interpretation that allow you to hear and feel a lyric's subtext: the emotions the songwriter hoped to evoke by a turn in the melody.

To Play or Not to Play

To Play or Not to Play

To put it mildly, Jack Vad (second row in photo, orange shirt) was dismayed. The Grammy Award–winning media producer and chief engineer for the San Francisco Symphony had just returned from the 2014 Rocky Mountain Audio Fest, and was trying to make sense of his experiences there. When he'd carried his latest recordings, which I think are superbly recorded, into rooms at the show and asked if he could play them, exhibitors were anything but enthusiastic.

What, a recording of rock backup tracks? Who could care less? Me, is who. Quibble over the program if you will (actually, it isn't all that dull, and two of the numbers are fun to listen to), but this wasn't released for the program material. You might call it a tantalizing sample of where a lot of rock sound begins, before it is fuzzed, reverbed, and cross-dubbed God knows how many times before the final mess is released for the edification of the peons. This has to be one of the most astonishing rock recordings ever issued! The Absolute Sound's Harry Pearson (who obviously got his before we got ours, as you are reading this 9 weeks after our copy arrived) is quoted on the jacket as declaring this to be "Absolutely the best-sounding rock record ever made." He's right.

Recently, we've been asking a representative sample of Stereophile subscribers for suggestions as to how the magazine could be improved. We got 'em, in droves. And the one thing that led every list of suggestions we received was: "Publish more often!" Second in importance was: "Do more reports on affordable components, and let's have more suggestions for cheap ways of improving existing systems."
