My marketing director Bill Leebens introduced me to Jonny at the Newport Audio Show a few months ago. I wanted Bill to guide me to some speakers that would work with my nifty low powered single-ended tube amps that I have but can't really use because of the low watts. He steered me right to the Sonist Audio suite. I'd like to say we had a nice chat but basically we listened to music in the room. I liked what I heard and was impressed that the late Randy Bankert's Sonist Audio brand was in such good hands. So, three boxes arrived yesterday for a long-term loan from Sonist Audio and Snake River Audio (both now run by Jonny Wilson). In the Snake River box was a beautiful 3 meter long pair of hand made, cryo'd COTTONMOUTH bi-wire speaker cables. In the two big boxes, the flagship speaker of Sonist Audio, the CONCERTO 4 speakers. Frequency response 27hz-40khz, impedance, a nice 8 ohms and, most importantly, sensitivity: 97db, dudes! That's right. My dinky amps can drive these speakers (so I was told). Since I had only heard the baby Concerto 2's at the show, I had no idea what these were going to do for me but I had faith and was hoping against hope that I would luck out with good sound (not too etched, not too this, not too that). Was I rewarded? Read on. The speakers have SOLID Poplar baffles and cabinet tuning that prevents bass bloat, a problem with this type of speaker design. Hard-wired first order crossovers, time-aligned ribbon tweeters, and so on. A good design. Now that Snake River Audio has the company, the design has been upgraded with cryo'd gold/silver/oxygen-free copper internal wiring. The Concerto 4's are 40" high, 12" wide and 15" deep. Not too big, just right for almost any room. The list price for these speakers is $5,895.00. So, how do they sound? Well, the pair I was sent were nicely broken in and since I have a nifty Audio Note UK system upstairs, I decided to make a system in the living room where there is a lot of room, very high ceiling and a chance to put these through their paces. Since I didn't (read: couldn't) carry the 85 lb Audio Note JINRO amp downstairs, I used my WOO AUDIO WA5 single-ended 300b integrated. I put it with an Audio Refinement CD player that Jeff Dorgay of Tone Audio gave me, cabled with my Stereolab Master Reference 838 interconnects and a Kubala-Sosna EMOTION power cord and I was ready to go. Warmed it up for like 3 minutes and couldn't wait anymore. What WAS this going to sound like? 8 watts to fill that gigantic room? Would it sound like most speakers of this type that I've heard? Boomy bass, too much midband honk, etc.? Or would it sound more like the smooth Audio Note AN-E/LX-HE's that I have upstairs? I played first some of my Nat King Cole stuff I mastered, to get a feel for how the speaker actually sounded with a lifelike human voice, then I blasted out some Matthew Sweet (just had it handy). Great sound! Lifelike, sensitive, punchy when needed, natural, dynamic, realistic, Chameleon-like (a good thing). Whatever I played on the system sounded like it was supposed to (I know how it should sound very well) but it had even more. It had that holographic 3-D sound that comes from a pure single-ended low powered directly-heated triode amplifier, being faithfully reproduced by a speaker designed to do just that. The soundstage was tremendous. I felt I could reach out and touch the performers. A speaker that works with my Audio Note Jinro, WAVAC EC300b and Woo Audio low powered amps. A dream come true. I am impressed and happy. If YOU have a low powered single-ended amp and have been stuck with "horny" sounding speakers, try the CONCERTO 4. You will be quite impressed as to what it can do. Trust Steve.
