Collection: Power Amplifiers

A power amp, also called a power amplifier, is the muscle of the amplification stage and delivers the power for the speakers, controlled by a separate preamp.

It does exactly one thing, namely deliver power, and in a separate setup it does that really well.

Why a power amp?

Because separating preamp and power stage allows maximum control and clean drive, especially with speakers that really demand something. From a fine stereo power amp to a mono block that dedicates its full power to a single speaker alone, this is the design for uncompromising setups.

What matters

Power amp and preamp need to match in level and connections, otherwise the duo won't harmonise. Power amps are high-end territory, and that's where marketing and music part ways. At HD Zürisee in Wädenswil we'll tell you honestly whether a separate solution really brings more audible benefit with your speakers than an excellent integrated amp.

Who are power amps for? (Straight talk)

For anyone who deliberately chooses separate components and drives speakers with real demands. Straight talk: nobody needs this as a standard solution, and a power amp without a matching preamp is just an expensive paperweight. But if you're after the last word in control and headroom, you're in the right place.

Our verdict

A power amp is the deliberate step into high-end when integrated amps reach their limits — not a must-buy, but a conscious decision. Tell us which preamp and which speakers are involved, and we'll find the power amp that fits.

Frequently asked questions

Power amp or integrated amp?

A power amp absolutely needs a preamp in front of it and pays off if you specifically want more control and headroom. For most systems, an excellent integrated amp is the smarter and cheaper solution. We'll tell you honestly whether separating them really brings something audible to your setup.

Stereo power amp or mono blocks?

A stereo power amp amplifies both channels in one chassis; mono blocks dedicate a separate unit to each speaker and fully separate the channels. In high-end territory that's audible, but the cost in space, cables and budget scales accordingly. We'll give you an honest assessment of what makes sense for you.

Which power amp suits my preamp?

Level, input impedance and connections need to match so preamp and power amp harmonise cleanly. Ideally both come from the same maker or are matched to each other. Tell us your preamp — or we'll already know it — and we'll combine it consistently.

How much power should a power amp have?

As much as your speakers and your room demand, not as much as possible. Demanding or large speakers in large rooms benefit from headroom, efficient speakers need less. We'll work out the sensible power for your combination instead of chasing the biggest number in the brochure.
