Michael Lavorgna reviews the L2 Signature Preamplifier & Monoblocks (Part 1/2)

…the Vinnie Rossi L2 Signature components offered some of the most musically satisfying sound I’ve heard in the Barn. Bravo!

“The Vinnie Rossi L2 Signature system goes deep. Way, way deep into the music. The overall presentation is rock solid, super stable, squeaky clean and precise coupled with a full boded and rich but not over-ripe sound.

The L2 system made my DeVore’s sound like new speakers, capable of things hereto only imagined. Bass response in particular was better than I’ve heard from the Xs and by “better” I mean in every meaningful way which includes tone, body, weight, and impact. The sound image completely decoupled from the speakers, filling the barn with stereo-defying presence in every dimension. Sounds picked, plucked, strummed, and sung sprung from all over the damned place like a sonic fireworks display. At the same time there was a tactile sense of the subtle, a caressing of micro-detail and nuance, allowing time and timing to create tension and release, the stuff that turns hifi into a moving musical experience. Balancing and delivering all of these traits is, in my experience, something special.

I’ve been following Vinnie Rossi’s hifi products going on 15 years and I am happy to see, hear, and report that he has arrived at the deep end of the pool with a truly satisfying splash. Coupled with my source and speakers, the Vinnie Rossi L2 Signature components offered some of the most musically satisfying sound I’ve heard in the Barn. Bravo!”


Anthony Kershaw reviews the L2 Signature Preamplifier

…It could live in my system happily. Forever. Very highly recommended.

…As Rossi suggests, the preamplifier is dead silent. No tube rush, nothing. A black background for the musicians to paint their sounds. During the break in, I had become enamoured with its sound during my standard sneak peeks. Warm, rich and refined, yet with incredible detail. All instruments shone with the most beautiful halo of vibrant sound. Vocals, too. Deep, rich, throaty. But with a harmonic ‘completeness’ to their presentation. Almost tactile. And definitely goosebump time. I could imagine the artists smiling and nodding with pride if they heard this type of playback.

…The L2 enhanced my very fine digital setup, and considering the preamplifier section of the Continuum S2 (basically, a Jeff Rowland Capri II preamplifier) is outstanding and an obvious match for its connected amplifier section, it couldn’t better the gorgeous sounds the 300Bs were portraying. For sure, a completely different topology, but the way Rossi has his tubes singing is very persuasive.

…Adding this fantastic bit of kit will elevate your musical experience into regions you have yet imagined. “


Jack Roberts reviews the L2 Signature Monoblocks

…These are simply very seductive sounding amplifiers.

I think the first two things you will notice about these monoblocks is their bass and their soundstaging. Whether kettle drums, a standup bass or a big pipe organ these amps have iron-fisted control of the bass. The bass is also deep, fast and powerful.

The second thing I noticed was the soundstage, and it was huge. With the L2 Signature amps in my system, the soundstage floated behind the speakers and way to the outside of the speakers… The L2 Signatures allowed my system to do this better than any amp I have heard.

The midrange has a wonderfully natural, relaxed, liquid, sweet and warm sound. Sinatra, or Ella’s voices or Ben Webster’s sax all sounded so relaxed and effortless. These power amps enabled me to hear layers of tones and textures of the music that came out of a very natural sounding background of silence. Performances were quite involving and moving at both low and loud listening levels.

With these amps, my system also had the capability to let me hear the lushness from the strings and woodwinds. When you combine this midrange with the bass I talked about above, you have a real winner on your hands.”


The L2 Signature Preamplifier receives very rare Lunar Eclipse Award!

The global market has nothing at all like it.  L2 is the first and only one of its kind… 

“The 12AU7 in Nagra’s Classic just couldn’t compete against the [L2 equipped with] Takatsuki 300B…
This underscored at least in my private appointment calender how today’s L2 truly was a class apart to justify its tariff in full. There was no sense comparing it to other preamps… Hifi reviews aren’t blood sports…

Vinnie’s L2 now allowed one to clone advanced SET attributes from properly spec’d transistor amps. De facto it meant, 1) hitching that type sound to SET-unfriendly ‘normal’ speakers, and 2) doing so with no impact on musical choices.
A solution as elegantly simple as Vinnie Rossi’s L2 Preamp we might have expected from one of the big established tube houses like Audio Research, Conrad Johnson, VTL… yet none of them—not one!—managed. The global market has nothing at all like it. L2 is the first and only one of its kind…

L2 stands alone. It also does in offering that very practical alternate tube-less path of Jfet buffer for when your glass may be down awaiting replacement, or for when you need a bypass. It does so with its 2.5V, 4V and 5V toggles which take tube specimens from all three voltage families. It does so with its optional DAC and phono boards, with its special-order headphone amp module. To anyone who’s been in hifi long enough to know that invariably, you can find something very similar behind a different face plate, the Vinnie Rossi L2 is a major stumper. With it, there just isn’t, period…

With the Vinnie Rossi L2 line stage, that well-trodden claim—of direct-heated triodes being the most linear low-distortion audio gain devices ever made—has finally grown legs to stand on and not just walk but sprint like a racer… As now truly themselves without the traditional crutches or interpreters, they finally step into the bright light of day with genuine purity and speed. And that equals bandwidth, noise and resolution figures which are on par with the best of transistors. The resultant sonics are very special!”
