Audio Analogue ABsolute PA 3.0 Stereo Power Amplifier, Black

The Audio Analogue ABsolute PA 3.0 is a stereo power amplifier from the ABsolute reference line with 300 watts Class AB and a circuit that manages without global feedback.

In black, it disappears into the rack; in operation, it disappears sonically – and both are exactly the intention. A power amplifier isn't supposed to have a viewpoint of its own; it's supposed to drive the speaker and otherwise keep quiet.

Why the ABsolute PA 3.0?

Because power alone is worth nothing if it doesn't arrive under control. Instead of feeding part of the output signal back to smooth the measured values, the ABsolute line draws its linearity from the circuit design itself – designed under the AIRTECH signature, hand-built in Italy. The 300 watts Class AB deliver the cushion demanding speakers call for, without making a big deal of it.

What you'll hear

Structure, especially down low. The bass gets contour instead of bulk, drums sound like skin and wood instead of effect, and when a track gets dense, you can still tell who's playing what. Only when you switch back do you notice how much work a good amplifier has quietly done in the background.

Who is the ABsolute PA 3.0 for?

For listeners with an existing preamplifier who deliberately want to separate the drive – ideally with the ABsolute Preamplifier from the same line. Straight talk: it doesn't play on its own. Without a preamplifier, input selection and volume are missing, and if you don't want to fit a second device in the rack, you'll have a far more relaxed time with the ABsolute 3.0 integrated amplifier.

Our verdict

A power amplifier for people who already know their system and just want to eliminate the one remaining weak point. No effects, no frills, but plenty of headroom.

Frequently Asked Questions

What's the difference between the PA 3.0 and the ABsolute 3.0?

The ABsolute 3.0 is an integrated amplifier with a built-in preamp, the PA 3.0 is a pure power amplifier. Both operate in Class AB without global feedback. You choose the PA 3.0 if you want to set up preamp and power amp separately and upgrade them independently later.

Is 300 watts enough for large floorstanding speakers?

As a rule, considerably more than enough. With large speakers, it's rarely the raw wattage that decides, but the ability to deliver current even at low impedance. That's exactly what the Class AB engineering of the ABsolute line is geared towards.

Can I run two PA 3.0 units bridged?

We don't have confirmed manufacturer data on this, so we won't claim anything here. If you're thinking about mono operation, the ABsolute PA Mono is the model built for that. Ask us and we'll clarify the bridging question directly with the distributor.

How much space do I need for the amplifier?

Units in the ABsolute line are large and heavy and belong on a load-bearing, well-ventilated piece of furniture. We'll get the exact dimensions and weight of the PA 3.0 directly from the distributor on request, so you can plan with confidence before delivery.

Why buy the ABsolute PA 3.0 from HD Zürisee?

Because with a power amplifier, we ask questions first instead of selling straight away: which preamplifier, which speakers, which room? As an authorized Audio Analogue dealer with our own technician in-house, we then also handle delivery, setup and service.
