Recording of August 1964: Vaughan Williams: Symphony No.2

Vaughan Williams: Symphony No.2 (A London Symphony)
Hallé Orchestra, Sir John Barbirolli, conductor.
Vanguard Everyman, SRV-134-SD (1963 LP). Reissued in 1982 as PRT Collector GSGC 2035 (LP). Recorded by Pye (UK) in 1957.

This is undoubtedly the best London Symphony that's been committed to stereo to date, and I wouldn't be surprised if it held top place for years to come. I can find nothing to criticize about the performance, and the recording is awe-inspiring—rich, warm and natural, with some phenomenally low bass and very wide dynamic range, yet without the slightest audible…

Conspicuous Consumption?

"At what price does a high-end product cease to exist for the 'normal' audiophile?" This question, which I asked in the February 2017 issue, was a follow-up to one I'd asked in our April 2011 issue: "If all someone is offered is a $150,000 pair of speakers . . . that person will walk away from this hobby, or build his or her system by buying only used equipment. Either consumer choice turns the price spiral into a death spiral for manufacturers."

Yet this issue sees me reviewing a loudspeaker that costs $215,000/pair. Last month I reviewed an amplifier priced at $55,000. In August,…

Rogue Audio Stereo 100 power amplifier

When I began writing for Stereophile, I dreaded doing comparisons. They were stressful and tedious—and what if I got them wrong? But I quickly learned: Not only do readers enjoy comparisons, they need them. How else might they imagine the relative merits of the component under consideration? Once I realized this, I began acquiring a range of reference amplifiers, such as the low-power Pass Laboratories XA25 and PrimaLuna ProLogue Premium, the high-power Bel Canto Design e.One REF600M monoblocks, and the single-ended Line Magnetic LM-518 IA. I also collected a range of affordable, popular…

Rogue Audio Stereo 100 power amplifier Page 2

In either mode, the Harbeth M30.2s were obviously well-tempered and well-nourished, power-wise. Both modes delivered detailed sound that was neither warm nor cool, just well balanced. The bass was tight and clean, maybe slightly lean, with no overhang or fuzzy harmonic additives.

Ultralinear mode was more sharply focused than Triode. In UL, music's empty spaces seemed too empty, in a slightly unnatural way. I felt I was receiving less information, that those empty spaces had once been occupied by texture, color, light, and shade. UL seemed higher in contrast. In Triode, voices and…

Rogue Audio Stereo 100 power amplifier Measurements

Sidebar 3: Measurements

I measured the Rogue Stereo 100 amplifier using my Audio Precision SYS2722 system (see the January 2008 "As We See It"). Before doing so, I installed the KT120 output tubes and, following the instructions in the manual, checked each tube's bias current. These were all around 50mA rather than the recommended 40mA, so, using the supplied tool, I adjusted the four trim pots. I checked the bias currents several times while performing the measurements, but none of the tubes had drifted from the recommended 40mA. The Stereo 100 has both balanced and single-ended inputs…
