If speakers were cars, the Infinity IRS Beta and B&W 801 Matrix would represent the luxury end of the mass market, with perhaps the Celestion SL700, Quad ESL-63, and MartinLogan Sequel II analogous to rather hairy, temperamental sports cars—the Porsche 911, for example. But most people don't buy Porsches, or even Lincoln Town Cars; they buy Hyundai Excels and Ford Escorts. In the same way, when the car is garaged for the night, they don't sit down in front of IRS Betas; in all likelihood they listen to their records with a compact two-way design. If competently designed, a small two-way can give a great deal of musical satisfaction, and, to take a current hobbyhorse of mine out for a trot, if a designer can't produce an at least competent two-way loudspeaker, he or she has no business trying to design larger, more ambitious models—there's nowhere to hide your lack of talent if all you have to play with is a tweeter, a woofer, a rectangular enclosure, and a handful of crossover components.

Editor's Note: in the main, Stereophile has steered clear of DIY audio projects, leaving them to magazines like The Audio Amateur, which was published by the late Edward T. Dell. But one of the exceptions was this 1967 article on the "Brute," a tube amplifier design by none other than Ed Dell. Note that the DIY competition mentioned by Gordon Holt is long closed to entries.—John Atkinson

There's a platitude to the effect that the road to Hell is strewn with good intentions. Well, we don't see ourselves as headed for perdition, but we must admit that we are surveying a rather impressive-looking junk pile of good intentions at this point.

For the past eight months, my headphone of choice at Stereophile's New York office has been a pair of AudioQuest Nighthawks. That's eight hours a day, five days a week, for approximately 32 weeks. Not eternity, but we've spent a good chunk of quality time together. The overall setup is comprised of an Apple MacBook Pro (usually streaming Tidal, Spotify, or Amarra for Tidal), an AudioQuest Jitterbug, an AudioQuest DragonFly Red, and said NightHawks. I suppose it's safe to say that my ears tend to jibe well with AudioQuest products.

Saturday November 26, Canadian high-end store Audio Excellence (661 Chrislea Road. Unit 1, Vaughan, Ontario, Canada L4L 8A3) is holding an all-day event featuring Bill McKiegan, president of Dan D'Agostino Master Audio Systems. Bill will be presenting the new Progression Mono amplifiers (above).

If I told you that Pass Laboratories' INT-60 integrated amplifier ($9000) was engineered by meth-lab trolls, its faceplate was wonky, its transformers buzzed, and it made every instrument sound like a tambourine, you'd think I was a crackpot with some kind of axe to grind, right? Because I suspect that, like me, you've never experienced or even read about a Pass Labs amp that didn't sound good.

In the February 2010 issue of Stereophile, I reviewed Bryston's first standalone digital-to-analog converter, the BDA-1 ($1995). Five years later, Bryston released the BDA-2, which replaced the BDA-1's 24-bit/192kHz Crystal CS-4398 DAC with a pair of AKM DAC chips in balanced mode. In a February 2016 Follow-Up (footnote 1) I reported that the BDA-2 deepened and widened the BDA-1's soundstage, among other performance gains.
