THIS LISTING IS FOR A FLOOR SAMPLE.
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, grounded-grid 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 bandwidth, phase, speed and directness, nor any distracting effects of driver tubes, coupling caps or output transformers to reproduce music 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!
