Sidebar 1: Review Context
The amplification was either a Mark Levinson No.25/No.26 preamplifier combination or an Audio Research SP14 driving my 1986-vintage Krell KSA-50.
Speaker cable was 15' lengths of AudioQuest Clear Hyperlitz, doubled-up for biwiring, while interconnects were 1m lengths of AudioQuest LiveWire Lapis connecting CD player to preamp, and preamp to power amplifier (1m lengths of Magnan V—an excellent cable—also served). Six-foot lengths of Madrigal unbalanced HPC connected the No.25 to the No.26. Source components consisted of a Revox A77 to play my own and…
Sidebar 2: Measurements
I use a mixture of nearfield, in-room, and quasi-anechoic FFT techniques to investigate possible objective factors that might explain the sound heard (footnote 1).
As the Amrita MiniMonitor features first-order crossover filters, which can be time-coherent in behavior, I investigated the speaker's response to a 25µs rectangular pulse (fig.1). Fig.2 shows the manner in which this pulse shape is modified by the Amrita when the measuring microphone is on the tweeter axis, plotted over a 5ms window. The drivers appear to be connected in phase, but the up/down…

When Tom Norton asked if I'd like to review an entry-level turntable from SOTA, I responded with a resounding "Yes!" I've long felt that there's a conspicuous absence of affordable, good-sounding record players on dealers' shelves. With the AR ES-1 package deals no longer available and the Rega 3 now selling for $775, at $599, SOTA's new Comet promised to be stiff competition for the Basiks, Revolvers, Duals, and Thorenses of the world. Also, due to my tenacious embrace of vinyl, I try to encourage as many music lovers as I can to experience the satisfaction derived from LPs and the fun and…
Sound
I was immediately impressed with the sound of the Comet/Special combination. When Tete Montoliu ripped into the changes on John Coltrane's "Giant Steps" on Montoliu's 1976 album Tete! (Inner City IC 2029), it was clear that the Comet could not only keep a beat, it could easily convey the emotion—all the fire and passion—in this underrated musician's performance. The recording is closed-in and up-front, putting you on stage with the musicians. That's where the Comet/Special combo put you. You could hear three musicians hard at work with all the attendant extraneous noises. On a…
Sidebar 1: System
My reference system is not what I'd expect the prospective Comet purchaser to own. Much to its credit, however, the Comet was not intimidated by the lofty components with which it shared shelf space. In fact, it acquitted itself quite well (more about that later). The phono signal from my reference turntable—a Well-Tempered Turntable sporting the new Black Damped Platter, with a Roksan Shiraz MC cartridge strapped to the arm—is handled by Counterpoint's impressive, two-chassis SA-9 Isolinear Phono Equalizer. Since the SA-9 has inputs for both MM and MC cartridges, it…

"Mastered from the original tapes to 180gm vinyl for the ultimate audiophile dorkout."
Now, now, Tommy Stinson, your website implies that "ultimate audiophile dorkout" is somehow a weird thing. Well, maybe it is but to most Stereophile-ers, that's just fancy talk for a real good time.
Not that long ago, the dominant equation when it came to physical media was focused on which recordings had not made the jump from LP to CD. Now, in a still mind-boggling turn of events, the question has become what about the digital recordings, made mostly in the last decade of the last century,…
