Big tube amplifiers were once scary monsters reserved for those who didn't mind heavy maintenance, careful tweaking, and the occasional explosion. Blown tubes required replacing, preferably with pricey matched pairs, then biasing with a voltmeter. Optimal sonic performance required regular bias monitoring and adjusting, and because of current surges on startup, you had to choose between leaving the heat-producing monoliths on, or turning them on and off for each listening session, thus shortening the life of the tubes.

Saturday, May 3, 1–5pm, Fidelis, located at 460 Amherst Street, Nashua, NH will host a seminar and open house with Peter McGrath of Wilson Audio (above) to celebrate and present Wilson Audio's new Sasha 2 loudspeaker. Brian Zolner of Bricasti Design will be on hand to talk about digital solutions and his highly regarded Bricasti M1 DAC, and Stereophile Senior Editor John Marks will be on hand to share his industry insights. Refreshments will be served. RSVP is appreciated: email store@fidelisav.com or call (603) 880-4434.

From whatever vantage point you choose, AXPONA (Audio Expo North America) 2014 in Chicago's Westin O'Hare was a major success. Attendance on opening day, Friday, April 25, was quite robust, and the feeling in the hallway and in rooms was extremely positive. Saturday was mobbed, with standees in many rooms during peak hours, and hallways buzzing.

Some of the best sound at AXPONA filled Chicago-based dealer/concert pianist George Vatchnadze's room. With more than a little help from industry veteran Dan Meinwald, who not only claimed to have simply plunked everything down, but also called the large room at the end of the 3rd floor of the Westin O'Hare "the best hotel showroom I've ever been in," Ella's "Angel Eyes" from her universally lauded LP, Let No Man Write My Epitaph, sounded drop-dead gorgeous. The midrange felt like a warm embrace, inviting me in without fear of witnessing Fitzgerald's emotion drowned in a sea of euphonia.

Is this the third consecutive show where the sound of Balanced Audio Technology (BAT) electronics has won me over? BAT doesn't need to either sugar-coat or tone down its tube sound, because its openness, clarity, and musical truth are so spot-on. IMHO, of course. The sound was so good that I didn't even bother to take notes on the music I heard.

Mated with the new Avid Ingenium turntable with Pro-ject tonearm ($1999), Marantz PM14S integrated amplifier, and Audioquest cabling, a not fully broken-in set of Wharfedale Jade 1 loudspeakers ($1199/pair) sounded very impressive for the price. On the Cowboy Junkies Whites Off Earth Now LP, a take-no-prisoners depiction of electric guitar was balanced by a decent midrange, good bass, and a fine depiction of female voice. Abetting bass response was Wharfedale's Diamond 10.2 subwoofer ($799), which filled in between 35 and 65Hz.

I enjoyed my short time with the Vienna Acoustics Imperial Series Liszt loudspeaker system ($15,000/pair). The Liszt incorporates Vienna Acoustics' flat-spider 6" coincident midrange driver and 1.2" vented silk-dome/neo-coated motor, as well as three 7" woofers that cover the 26–200Hz range of a speaker that extends up to 25kHz. Mated with a Primare I32 integrated amplifier ($4750), whose pre-installed full media board option allowed a wired LAN connection to a NAS drive, and AudioQuest cabling, the system depicted a file of a recording of Mahler's Symphony 3 with superior midrange, fine bass, and appropriate top-end bite. Percussive slam was tight, if a bit shallow, but that may have been due to the recording itself.
