I examined the Audio Research VSi60's measured performance with Stereophile's loan sample of the top-of-the-line Audio Precision SYS2722 system (see the January 2008 "As We See It" and www.ap.com); for some tests, I also used my vintage Audio Precision System One Dual Domain. I checked the bias of each output tube after letting the amplifier warm up for an hour and before I did any testing. All the tubes had exactly 60mV of bias, as specified, and didn't need adjustment with the top-panel potentiometers, which suggests good stability.
I had one mishap…
I admit that, when I made up that nonsense, I had certain vegetables in mind. But late one night, when an unpleasant bout of thinking kept me awake, I realized that there are a great many older people, such as myself, whose belief systems could…

To perform the measurements on the Electrocompaniet AW400, I mostly used Stereophile's loan sample of the top-of-the-line Audio Precision SYS2722 system (see the January 2008 "As We See It" and www.ap.com); for some tests, I also used my vintage Audio Precision System One Dual Domain.
Electrocompaniet refers to the AW400 as a "Class A" amplifier, but the heat signature and the idling power consumption suggests that it uses a conventional class-AB output stage. I preconditioned the Electrocompaniet by running it at one-third power into 8 ohms for 60 minutes…
But singing in church is one thing, and burning heretics is quite another: From time to time I'm troubled to wonder if an even greater degree of enjoyment could have been mine, if not for my slavish devotion to the indestructible beat of the flat-Earth doctrine, with its…
