CH Precision A1.5 Two-channel Power Amplifier CPO Certified

CH Precision A1.5

Certified Pre-Owned • Factory Updated • Reference Performance

We are pleased to offer a superb Certified Pre-Owned CH Precision A1.5 Power Amplifier, now in stock at Sunny Components Inc.

2-year CH Precision Warranty. 

This amplifier was initially purchased from us by a valued client who has since upgraded to the magnificent M10. As part of CH Precision’s uncompromising Certified Pre-Owned process, the A1.5 was professionally packed and returned to Switzerland, where it underwent complete factory testing, inspection, and updating. During this process, the amplifier received:

• All current production boards

• A new display

• Full verification to current factory performance specifications

It returns to us performing at the same level as a new amplifier, backed by CH Precision’s exacting standards.

“Honey, I Shrunk the Amp…” — Without Shrinking the Performance

Faced with exactly the same design challenges as the legendary M1.1, the A1.5 embodies the same sophisticated, modular, and scalable architecture that defines CH Precision amplification. While it is slightly smaller and approximately two-thirds the weight of the M1.1, it is—quite literally—four amplifiers in one.

In every way that matters, the A1.5 is an M1.1 written small:

• Identical software-controlled, configurable topology

• Adjustable input configuration and gain

• User-selectable global feedback ratio

• The same ultra-short signal path

• Fully discrete, fully balanced, fully complementary circuitry

• Built with the same carefully selected components to the same uncompromising standards

• Identical casework footprint, construction, and mechanical grounding / stacking system

Even the power transformer and reservoir capacitance are of the same type and design as those used in the M1.1.

Real Power, Real Authority

While the A1.5 does not aim to eclipse the M1.1’s extreme headroom in the very largest rooms or under the most punishing loads, it is no lightweight. Conservatively rated at 150 watts per channel, the A1.5 delivers:

• Real dynamic range

• Authoritative bass control

• Effortless drive with demanding loudspeakers

• Transparency, resolution, and musical communication equal to its bigger sibling

In many systems, with many speakers, this is exactly the power you need—and can actually use.

In any other product range, the A1.5 would be the flagship amplifier. Here, it delivers performance to match.

Scalable, Configurable, Future-Proof

Like the M1.1, the A1.5’s brilliance lies in its adaptability. User-configurable via the front panel or the CH-Control App, the A1.5 can function as:

• A conventional stereo amplifier

• A high-current mono-block

• A high-power bridged mono-block

• A highly flexible bi-amplification platform

Add a second A1.5, and the amplifier becomes considerably more than the sum of its parts. Vertical bi-amping allows:

• Independent gain and feedback adjustment per channel

• Improved bass control and room matching

• Significantly increased system headroom and dynamic ease

This scalability allows the A1.5 to grow with your speakers, your room, and your musical ambitions.

The Not-So-Little Power Amplifier

With the same transparency, resolution, and engaging musical qualities as the M1.1, the CH Precision A1.5 is an extraordinarily capable and convincing performer—one that punches well above its weight, both sonically and conceptually.
