Counterpoint Natural Progression NPS-400 power amplifier

Amplifier designers have frequently looked for ways to marry the advantages of tubes to those of solid-state devices. Hybrid designs of various stripes have appeared over the years, most of them using tube input stages with transistor output stages, eliminating the major weaknesses of tube amplifiers: eg, they run hot, are unreliable in that tubes have a finite life, are more expensive than a similarly powerful solid-state design, and have power-hungry output tubes and output transformers.

Sennheiser HE 60 headphones

In February 1994, when I reviewed the pricey ($12,900 with amplifier) Sennheiser Orpheus headphone system—HE 90 headphones and HEV 90 D/A processor/amplifier—I commented that the company had a similar, but less expensive, alternative available: the HE 60 headphones combined with the HEV 70 amplifier. At the headphone end, the HE 60s aren't so different from the HE 90s furnished with the Orpheus system. Both are extremely lightweight and supremely comfortable—even for long listening sessions (I logged up to four hours without a break on the HE 60s). In fact, the less-expensive HE 60s are about 100gm—4 ounces—lighter than the HE 90s.

Stax SR-Omega headphones

Ah, yes, headphones again. The market for super–high-end headphones must be small, but manufacturers nevertheless keep introducing new designs. At least two manufacturers—Stax and Sennheiser—seem to have carved out a big chunk of this market for themselves, and are currently slugging it out with their respective takes on the best that electrostatic headphones have to offer.

Monitor Audio Gold 300 loudspeaker

About a year after settling into my new house, I decided to buy a pair of Monitor Audio Silver 10 floorstanding loudspeakers, which I had reviewed in 2014 for our sister publication Sound & Vision. I wound up buying three of them, with the intention of cannibalizing the drivers and crossover from one to make my own three-way center-channel speaker. But that project was long delayed, and I never got around to doing anything with the third Silver 10: It now sits in a closet as a spare.

The Mod Squad Prism CD player

While it can't exactly be said that the folks from The Mod Squad invented the game of audiophile modifications of existing, current-production hardware, they certainly have grown to be one of the major leaguers. Their mods have a reputation for being well-thought-out, nearly always offering improvements over the originals. And while they weren't the originators of the concept, any company which brought the world Tiptoes (probably their most famous product) will probably have a niche in the 21st-Century Museum of High-End Audio.

Theta DS Pro Generation III digital processor

A visiting manufacturer recently expressed the idea that digital processors and transports are the worst value in high-end audio. He contended that, because they all sound bad, their differences and degrees of imperfection are meaningless. In his view, the very best digital differed very little from the worst. His advice? Buy a moderately priced CD player and enjoy your LPs.

Emotiva Audio Airmotiv T2 loudspeaker

Visit any consumer audio show these days and you'll see rooms full of systems costing from six to seven figures. Manufacturers like to put their best foot forward, and demoing systems with loudspeakers designed to sell for $50,000/pair and up (often up) seems an obvious way to go.

It's also common for an audio company to launch its flagship models first, and only later release more affordable products, for a wider range of buyers. The hope is that the promotional shine of the dream products will be reflected onto the budget models.

Q Acoustics Concept 500 loudspeaker

Q Acoustics was founded in the UK in 2006, but has appeared on the radar of US buyers only in the last few years. Until recently, Q has aimed its efforts at the budget sector, earning enthusiastic reviews and commercial success.

But during that time the company also been quietly working on a product considerably more upscale, though still affordable in a marketplace now glutted with products at if-you-have-to-ask prices. The result is the Concept 500 ($5999.99/pair), first seen in the UK in 2017 and recently made available here. But you won't find it at your local audio shop (if you still have one); in the US it's currently sold only online, through Q Acoustics' US website, with a 30-day, money-back guarantee that includes shipping costs—both ways.
