Cary Audio Design CAD-300SE LX20 monoblock power amplifier

Many tube aficionados hold that amplifiers built with the venerable 300B tube hold the aces when it comes to sonic purity and beauty of harmonic line. Cary Audio Design's Dennis Had succeeded in producing what many believe is the definitive moderately sized single-ended triode (SET) amplifier: the CAD 300SE. This monoblock, powered by classic 300B Western Electric or derivative tubes, could provide 8–10Wpc, requiring the adoption of relatively moderate volume settings and/or sensitive, easy-to-drive loudspeakers. Cary also produced a lower-priced "integrated" stereo chassis, the CAD 300SEI.

Lamm ML2.1 monoblock power amplifier

One of my best friends is a serious jazz collector with a side interest in good replay gear. The last time we got together over a meal, he asked, "What do you think is really the most important component in an audio system?" He might have added "these days": It's a subject we come back to from time to time.

Sonic Frontiers Power 3 monoblock power amplifier

The internal battle between the head and the heart, between the analytical and romantic sides of our nature, is a difficult one. I'm an engineer, so it seems as if my cold, calculating side should have the upper hand. This is true in a lot of cases; most of my actions and decisions are based on straightforward, logical analyses. However, things like a house full of castaway dogs, or a garage full of quixotic British cars and Italian motorcycles, suggest that my heart holds sway reasonably—perhaps distressingly—often.

Nobis Cantabile power amplifier

I dig tube amps. When all's said and done, good tube amps seem to sound more like real life than most solid-state gear; even after listening to and enjoying the hell out of musical solid-state designs like the Audio Research D-240 II and the Muse Model One Hundred, once I hook up the big VTL Deluxe 225s again it's just like going home. I could go on about timbral accuracy and clearer midrange textures, but the bottom line is, music just plain sounds better when you shoot it through good tubes, and once most people experience that magic, they're hooked.

Wavelength Audio Cardinal XS monoblock amplifier

We have to talk. Are you sitting comfortably? Is the reading light okay? Have a little something to drink at hand? (Audio is thirsty business.) The audio world is abuzz over the reintroduction of the single-ended triode amplifier. This is the first of three reviews of such amplifiers I'll be bringing you, along with two speaker systems with which to play them.

Antique Sound Lab Explorer 805 DT monoblock power amplifier

Anyone over 40 who's worked in a hi-fi or record store will remember the Pfanstiehl catalog, a pulpy thing that most shopkeepers chained to their counters, like a phone book. Pfanstiehl made replacement styli for virtually every record-playing device of the day, and their catalog contained page after page of tiny line drawings of nothing but phonograph needles, all lovingly rendered in three-quarter view. You couldn't browse it without being brought up short: My God, how many different needles are there? And how is it possible that a single company could tool up for so many products and still make a profit?
