Now, that is highly interesting up upcoming DHT preamplifier ($22k with DAC and phono stage) from Vinnie Rossi. “The L2 Signature Preamplifier is Vinnie Rossi’s new flagship design that creates an effortless connection between the listener and the music. Compatible with the most cherished of 4-pin directly heated triode (DHT) tube families, L2 delivers an unmatched listening experience with its exceptional resolution, tonality, and “reach out and touch the performer” sense of realism. Superb linearity and extra-wide bandwidth recover delicate nuances and provide incomparable texture, layering, and spaciousness. And when it comes to bass response, L2’s articulation of each and every note is phenomenal.”
At the heart of the L2 Signature Preamplifier is Vinnie Rossi’s latest Class-A, ultra wide bandwidth, DHT topology powered by patented Belleson super-regulated, dual mono linear power supplies. L2 exemplifies elegant simplicity and finesse in communicating all the emotion and passion in the music.
Each L2 Signature Preamplifier is meticulously hand-built and tested by Vinnie Rossi himself. Its no-compromise construction and use of the highest-quality components assure the listener of reliable performance for many years.

* Production of the L2 Signature Preamplifier, along with optional L2 Dac and L2 Phonostage modules (see tabs below) begins September 2018!
