Single-ended triode (SET) amplifiers are typically paired with horn loudspeakers, for good reason: most SETs produce very low power, so to get acceptable loudness you need a highly sensitive speaker, which means horns. Similarly, horn owners are often advised that the best amplifier for their speakers is a SET. Certainly, the horn-SET combination can be magical, but, in my experience, SETs are not the only type of amplifier that can sound good with horns.

Moderately Priced Speakers. That's my assignment for this year's CES show report—as well as moderately priced turntables and other phono equipment—Moderate being defined this time as priced from $4000/pair to $18,000/pair. Right at the top of this range is the $18,000/pair Raidho XT-2, an extremely slim floorstander that uses the same tweeter as the rest of the Raidho range and two 4" cone drivers.

Although many (maybe most) of the demos at the 2011 SSI were computer-based, vinyl continued to have a presence, notably in the Aux 33 Tours room, which had an excellent assortment of LPs for sale. And not all the people showing an interest in LPs were old fogeys, as the photo illustrates.

Red Wine Audio is the name of the company making amplifiers designed by one Vinnie Rossi, "an electrical engineer with a true passion for music and implementing the electronics that recreate it," whose name, if you pretend that Vinnie is spelled with one "n," means "red wine" in Italian. (Actually, "vini rossi" means "red wines," but let's not quibble.) What makes Red Wine Audio amplifiers interesting is that they're all battery-operated. The system being demoed used a pair of the Red Wine Audio Signature 70 monoblocks ($2999/pair), driving single-driver speakers ($2495 MaxHemp or $949 Super 3XRS) from Omega Speaker Systems. The source was a battery-powered computer server, so that the only AC-powered devices in the room were some table lamps. I can't say whether it was the battery power source or some other aspect of these designs, but the sound was uncommonly natural and easy-on-the-ears. The small Super 3XRS speaker, which uses a proprietary 4.5" Omega hemp-cone driver, had a coherence and focus that reminded me in some ways of the $7000/pair Fujitsu Ten Eclipse TD-712z single-driver speaker that I reviewed in the January, 2007 issue. Shown here are Vinnie Rossi (left) with Omega Speaker Systems' designer Louis Chochos and the Red Wine/Omega system.

Red Wine Audio has been expanding their range of battery-powered audio electronics: they have the Isabella preamp, with optional built-in DAC; Signature 30.2 power amplifier, with optional volume control, and Signature 70.2 monoblock amplifiers. The system at FSI used Omega Super Hemp speakers, which use a driver that in the version demoed at the show was equipped with an Alnico magnet structure, and it sounded very nice indeed.

Reev Designs is a new Toronto-based speaker company, with so far just one model: the large, stand-mounted Aetma ($6950/pair). It's a striking-looking speaker, with wooden extensions on each side that are said to be critical in controlling resonances. Frequency response is claim to extend from 44Hz to 22kHz, ±3dB.

Divergent Technologies’ Tash Goka introduced a new top speaker in the Reference 3A line: the Grand Veena ($7500/pair), which, in addition to two woofers, a midrange and a tweeter, also has a Murata supertweeter that covers the range from 20kHz to 100kHz. The sonic contribution of the supertweeter is acknowledged to be "not easily detectable by conventional means," but is said to improve the speaker’s spatial quality and have positive effects outside of its nominal operating range. The Grand Veenas sounded mighty nice driven by Antique Sound Labs' new Cadenza amps ($6500/pair).

Rega comes to affordable audio products honestly: that's the only kind they make. For $5000, the system assembled at SSI 2013 included the Brio-R integrated amp ($900), Apollo-R CD player ($1095), and RS7 speakers ($3195/pair). You can substitute a DAC or a turntable for the same price. If you do the math you'll find that this comes out to $200 more than the limit, but I was told that the dealer will offer a discount that brings the price down to $5000, and will even include some cables. A very easy-on-the-ears system, and obviously good value.
