The 2150 Mono Power Amplifier is the beneficiary of 30 years of amplifier design. It replaces the renowned 2050 Mono Power Amplifier, a benchmark product that stayed in continuous production for almost 18 years.

Great products don’t just appear out of nowhere, they evolve, built on the foundations of things that came before them. The Boulder 2160 Stereo Amplifier replaces and surpasses in every way the venerable 2060, a brilliant amplifier that earned dozens of awards worldwide. All of the electronics have been updated with leading-edge technology while the look has evolved with a style that is both subtle and elegant.

When it’s time to take your audio experience to the next level the, natural move is away from an integrated amplifier to a dedicated line stage and one or more power amplifiers. The RL-102 is the obvious choice of line stage when it’s time to make that leap.

You reach out to your pocket. Therein lies the key to advanced and futuristic technology. Gently you push… The system of the ultimate sports car becomes alive. An overwhelming feeling becomes you. Almost unlimited processing power becomes available to ensure pristine performance. It’s crystal clear that you’re in the drivers seat: impressed, but in control. All instruments call out to take it for a spin. Then you realize this fine piece of machinery is reference, top notch. You are right on track with the RD- 101 Stereo DAC.

Power corrupts. Absolute power corrupts perfectly. The Boulder 3050 Mono Amplifier, our flagship, is our most powerful, largest, and most luxurious product in over 30 years of sound system design.

Reference 16-channel 200-watt-per-channel amplifier. Pair with AV 10 to create an elite-level home theatre. Marantz HDAM, Current Feedback Amplification, and balanced line level input.

There are projects like the Boulder 3060 Stereo Amplifier that contradict conventions and redefine striving for perfection. Attempts are made to push the boundaries of what is thought to be possible. These projects involve countless hours of research, experimentation, and hard work, with each step along the way creating small improvements. When accumulated, each of these small improvements mean big leaps forward. They embody the concept of what it takes to be the very best and the results are breathtaking.

Just like the Boulder 3060.

This preamp is inimitable with a unique character. With the Conquistador everything started with a blank sheet of paper. Developing and designing a new project you must think outside the box, and scrutinize everything. This is the way the Conquistador was created, and it is a highlight in design and engineering art.

Four AA45 Mesh-triodes of our own proprietary production, coupled with the unique quadruple VTC volume control, a special circuit design with four separate tube grid bias drivers, and the shortest thinkable signal path underline this absolutely exceptional concept in the world of preamps.

Featuring technology derived from the aerospace industry, the Étude is an incredibly compact stereo amplifier with stunning power, speed and clarity.

For over 4 decades, Ayon Audio has been handcrafting world class vacuum tubes and vacuum tube audio equipment, setting the benchmark and new standards for high end audio performance. Altruistic reliability, product durability, Ayon Iconic design and superb resale value.

The TToby range may be ideally suited to compact living environments, but don’t let that fool you. With similar legendary amplification derived from our SPM range, TToby doesn’t compromise on power or providing you with the purest audio experience possible.

The new XP-12 starts with a new power supply. It uses an efficient toroidal design with both an electrostatic and Mu metal shield along with vacuum impregnating and epoxy fill. This gives us a very quiet transformer both electrically and mechanically.

The power supply circuitry itself is also lower noise and has additional filtering, a little more complicated but worth it.

Power and dynamics in this amplifier designed to achieve a high-impact soundstage. The heat of the tubes is based on a great and balanced dynamic. The PRO 88 are considered as being the tubes with a very high power while maintaining a wide dynamic range; this is an amplifier for those who want a refined power.
Integrated Amplifier in A-B1 class.

The new design uses double shielded low noise toroidal transformers in external supply connected via aviation grade circular connectors using silver over oxygen free copper. The power supply is dual mono with two transformers with lower radiated and mechanical noise. Noise is the most prominent part of THD+N at low levels, so by lowering noise we get better resolution and dynamics.

The gain circuitry continues to use our favorite transistors from Toshiba but has a larger, higher biased, output stage like the Xs Preamp, and includes auto bias.

In PassLabs we are constantly working on and listening to new circuits and components, increasing our knowledge and seeking better sound and enhanced product reliability. That time has come for the XP-32.

The new design uses uses double shielded low noise torroids in a true dual mono topology for the gain channels and another transformer, linear power supply dedicated to the control architecture.
