Weight: 12kg Shipping Weight: 24 kg including travel case Review REVIEW SUMMARIES Rocky Mountain Audio Fest 2018 Warmth and midrange smoothness were the strengths of a Vinnie Rossi/ Triode Wire Labs / Harbeth loudspeaker system Drums and percussion were depicted with excellence, the low tones of piano and instruments were conveyed with perfection, and the artistry and emotion of all concerned came through loud and clear. In fact, the brilliance of music and interpretation was such that, for one of the rare times in my 15 years at audio shows, absolutely no one left the room or even fidgeted during a long piece of relatively obscure, heart-rending German lieder that was impeccably sung with deep feeling. This is a tribute not only to Vinnie Rossi, Harbeth, and Triode Wire, but also to the quality of show attendees whom Vinnie tends to attract. Thank you, one and all. Jason Victor Serinus, Stereophile RMAF 2018 Best in Show Sound (Room 3018: Vinnie Rossi with Spatial Audio and Anticables) It s rooms like Vinnie s and Clayton s that really are the energy for that audio show feeling. Bass was massive and natural and by natural I mean it was like real thunder, not a facsimile, or one of those pesky apartment neighbors who just got Sub-Woofer: The Movie on Blu-Ray. The mid-range and treble was as effortless as anything I had encountered this year at any of the shows. Not to say it was out-right the best, but it was spooky in how it loaded the room and held voices inside the image when needed but allowed the vocals to show space when the recording demanded it. When we talk about Best-In-Show sound, I can t help but take into account that what I heard here at Rocky Mountain Audio Fest is not only a few extra inches of performance, but a few feet worth. How many other speaker and electronics brands can admit they ve made those kind of gains? Eric Franklin Shook, Part-Time Audiophile (Room 4024: Vinnie Rossi with Harbeth Loudspeakers and Triode Wire Labs) Insight was available by the boatload. Bass attack, fast, but not bloated or overly thumpy. Mid-range, what I consider to be signature Harbeth, but turned upward and wider that I know from my previously smaller Harbeth experiences. Treble was where, for me, things shined. The insight came from imaging that hung afloat in the middle of the room like an apparition. Eric Franklin Shook, Part-Time Audiophile Page 3/5
In the Spatial Audio room, Clayton Shaw was debuting his statement speaker, the Lumina L2 along with Vinnie Rossi s?l2 Signature Preamp and Monoblock System that he was debuting. This was some of the best sound at the show. This is one of the systems at the show that really got my motor running. The whole system didn t cost what many of the speakers at the show sold for, and it sounded better than most. It was dynamic, open, had emotional energy and was very natural sounding. These were great debut products. Jack and Becky Roberts, The Audio Beatnik The slide guitar-infused Plowin Mule track by Doug MacLeod posted almost ghost-like focus for each instrument in the music field. It was certainly hard to tell where the speakers were placed, and if pressed to gander a guess, I would have implied a location much further back, behind the somewhat close, actual placement of the 40.2s. A fun party trick? An expensive hollowed gesture to scare trick-or-treaters? I say nay. Raw craftsmanship from two brands that gel together for power when needed and grace unyielding. Best imaging and focus of the show for me. Brian Hunter, Audio-Head.com RMAF Best of Show This was one of those rooms you could sit and listen all day and never get fatigued. Vinnie had them [Harbeth 40.2s] dialed in and his new L2 DHT Preamp sounded terrific. You also won t meet a friendlier bunch than these guys! Mike Bovaird, AudioShark.org Great Rooms of RMAF 2018 Lovely sound, typical of Harbeth and its legendary status. Great bass, too Vinnie Rossi continues to make some of the most intriguing electronics, highly adaptable and sounding superb. Very good and reasonably priced.
