Vinnie Rossi L2i-SE Integrated Amplifier

"In its price class, it’s an apex predator. The L2i-SE was a performance of passion, gestalt, and simplicity”

Matt Clott - The Absolute Sound

Vinnie Rossi L2i Signature

Integrated Amplifier


The L2i-SE is our response to “what if?” What if we could combine our L2 Signature Preamplifier and L2 Signature Monoblocks into one chassis but with absolutely minimal concessions to design and performance? Could we still offer all the flexibility, build quality and stunning appearance to truly stand in a class of its own? The L2i-SE is Vinnie Rossi’s realization of that dream.

Unlike the L2 Integrated Amplifier (L2i), which runs a simpler 6SN7 linestage, the L2i-SE inherits from our L2 Signature Preamplifier the direct-heated big power triodes. Only one pair of the finest sounding 4-pin, directly heated triodes (DHT) are run in a dual-mono, class-A topology with zero feedback. They feed a true dual-mono, high-bandwidth class-AB MOSFET output stage making the L2i-SE a DHT hybrid integrated amplifier and likely the only one of its kind in the world! 

There are absolutely no compromises on speed and tonality, nor any distracting effects of driver tubes, coupling caps or output transformers. Music is reproduced with intense spaciousness, harmonic sophistication, liquidity and detail well beyond small triodes and pure transistors alike.


You get the same flexibility as the L2 Signature Preamplifier (flick-of-a-switch tube rolling, tube bypass mode, L2 Dac and Phonostage options) and the full-function L2 remote handset. Merging all of this with superlative build quality, reliability and a 10-year warranty make the L2i-SE a striking single-chassis proposition that sits just one step below our flagship separates!

Vinnie Rossi L2 DAC - Optional    $3,495

The L2 DAC is our latest, statement-level d-a converter module that allows music to flow in an effortless manner that mirrors true analog playback with its highly resolving and dynamic, yet non-fatiguing sound signature. No matter if you are playing PCM files from 16-bit/44.1kHz to 32-bit/768kHz or DSD files from DSD64 to DSD512, you will become captivated listening with Vinnie Rossi’s approach to digital playback.


L2 DAC Features

  • Bit-perfect playback at sampling rates up to PCM 768kHz (16, 24, or 32 bit compatible), as well up to DSD512. Sample rates are viewable from front panel display.

  • Dual-mono design, with one flagship AKM AK4497EQ d/a chip per channel.

  • Fully discrete, pure Class-A JFET analog outputs stage design with cascode constant-current source biasing (no opamps).

  • On-board FPGA buffer and femto-reclocking circuitry negates effects of jitter. Isolated input stages.

  • ‘NOS’ (non-oversampling) filter mode with digital filter bypass, as well as a Minimal Phase digital filter mode (selected via the “FILTER” button on the L2 Remote).

  • Absolute polarity ‘normal’ / Absolute polarity ‘inverted’ modes (selected via the “PHASE” button on the L2 Remote).

  • Belleson Super-regulated voltage feed to numerous ultra-low noise, linear voltage regulators used throughout (for both digital and analog sections).

  • “Silent” mute ‘reed relays’ (*barely* an audible click from the board when changing tracks of a different sample rate).

  • Inputs : 1 USB, 1 Coax (75-ohm BNC, with included RCA adapter) and 1 TOSLINK (optical).

  • Connect up to three devices and switch between them via L2 front panel or the remote handset.
