Lorenzo Audio Labs 2A3

Lorenzo Audio Labs presents the perfect companion to its impressive 211PP monophonic power amplifiers, the new 2A3 preamplifier with two chassis.

Following Lorenzo Audio's philosophy, only the best quality is allowed, both in terms of sound, design, and construction.

For this reason, as in the 211PP amplifiers, 40mm thick Panzerholz wooden bases are used in the main chassis and the power supply unit.

The 2A3 tube sockets are also CNC-milled from Panzerholz wood, as are the housings for the capacitors and the feet of the preamplifier. No detail is left out to achieve maximum sound quality.

Regarding its internal design, its most remarkable features are:

- Dual power supplies, one for high voltage and the other for filaments only, to minimize noise.

- With 80,000 uf, two chokes make this preamp with the magnificent Emission Labs 2A3 tube absolutely silent.

- Duelund coupling capacitors to achieve maximum naturalness and transparency.

- High voltage filtering system with MKP capacitors and 3 independent chokes.

- Zero negative feedback.

- High-resolution 66-step volume control operated via remote control.

- 6 RCA inputs and 2 RCA outputs

- Panzerholz chassis.

- 2A3 tube sockets CNC machined from Panzerholz wood, unique in the world.

The world launch of the 2A3 Preamplifier will be in the High End Munich, Hall 2, F12 / H01.

Lorenzo Audio Labs 211PP

Power Amp Monoblock 211PP

Lorenzo Audio Labs, in its tireless quest to raise the bar of sound reproduction to the highest level, presents its Lorenzo Audio 211PP monophonic tube amplifiers.

The state of the art 221PP amps are the best match for the Lorenzo Audio Labs loudspeakers as well as for lovers of the highest quality sound.

You are facing one of the best audio amplifiers that can be manufactured. Not only do they feature the best components, which we will detail later, but also a philosophy that accompanies us in all our products, reach the auditory perfection. Handcrafted manufacturing with the extensive use of Panzerholz wood, this type of wood is highly appreciated for its non-resonant properties and linearity across the entire audio range, combined with exquisite aesthetics using the finest woods, marquetry and meticulous high-gloss finish, making it a true work of art.

After years of testing and development, we have opted for a Push Pull configuration with direct-heated triodes, with the 211 tubes, providing the transparency and harmonic richness of a single ended but with unprecedented speed and attack, offering a powerful 55W with zero feedback. At the heart of this stage stands a double Core C amorphous output transformer weighing 12 kg, featuring the legendary 2A3 tube directing the 211 tubes through a phase shift interstage, accompanied by a series of state-of-the-art components, such as high-voltage MKP gel filtering capacitors with a lifespan of over 30,000 hours, and ultra-fast rectifiers. And to eliminate any residual noise, the filaments are equipped with over 140,000uF, all powered by a double power supply through two independent transformers for low and high voltage.

It is worth noting that all circuits are hand-soldered without printed circuit boards.

Specifications:

- All-tube, transformer-coupled, zero feedback, push-pull architecture - Tubes: 2 x 211, 1 x 2A3, 1 x 6E5P

- Frequency range: 15 Hz - 25 kHz +/- 1.0 dB
