AVM Evolution PAS 3.3 Streaming Preamplifier, Black

The AVM Evolution PAS 3.3 is a streaming preamplifier in pure transistor technology, combining a network player, D/A converter, phono preamp and analog preamp in a single unit – without a power amp of its own.

AVM has been building preamplifiers since 1986, and the PAS 3.3 is the Evolution series' all-in-one idea: every source goes in, a cleanly regulated signal comes out – to your power amp or to active speakers. You'll look for tubes here in vain, and that's by design: those sit in the sister model PAS 5.3, behind the glass panel in the lid. The PAS 3.3 works entirely transistor-based under a closed, brushed aluminum lid.

Why the Evolution PAS 3.3?

Because it can do almost everything except power amplification. HiRes streaming via the AVM X-STREAM Engine (Qobuz, TIDAL Connect MAX, Spotify Connect, AirPlay, Roon Ready, HighResAudio, UPnP, internet radio), a double-quad DAC with four ESS9028PRO converters per channel up to 384 kHz/32-bit and DSD256, a full-fledged phono preamp for MM and MC – and an HDMI ARC input, so your TV finally sounds as good as it looks. The PAS 3.3 controls volume entirely in the analog domain.

What you hear and get

A distinctly neutral, very low-noise sound that adds nothing of its own – plus a complete source stage on top: four analog inputs (3× RCA, 1× XLR), a separate phono input, two S/PDIF inputs, USB-A for hard drives, plus LAN, Wi-Fi and Bluetooth 5.0. Output runs via pre-outs in RCA and XLR, a fixed line-out and two digital outputs that can be level-controlled on request. Add to that a dedicated headphone amp, tone controls with parametric loudness, and a dimmable graphic display with proximity sensor. This version has its front and lid in brushed black aluminum. Streaming is an option here, not a must: internet radio, files on the network, USB, vinyl and TV sound all work without a paid subscription too.

Who is the Evolution PAS 3.3 right for?

Let's be honest: the PAS 3.3 is a preamp. It has no power amp and doesn't drive speakers directly – you need a power amp or active speakers behind it. In return, it's the heart of a preamp/power amp chain and bundles streaming, vinyl and TV sound at a level you'd otherwise spread across three devices. If you want an all-in-one solution with speaker terminals, you're better served by an integrated amp. And if you want tube warmth in the signal path, go for the PAS 5.3.

Our verdict

The PAS 3.3 is the no-nonsense variant of the Evolution preamp: neutral, quiet, technically state of the art, and with a connection list that leaves hardly any question unanswered. If you're building your chain around a good power amp but still want just one unit for all sources, this is one of the most convincing solutions in its class. At HD Zürisee in Wädenswil, we'll set it up with you – network, phono tuning and power amp matching included.

Frequently Asked Questions

Does the AVM Evolution PAS 3.3 have tubes?

No. The PAS 3.3 is a purely transistor-based unit and works under a closed aluminum lid. The tube line stage behind the glass panel belongs to the sister model PAS 5.3. Connections, converter and phono section are identical on both – the difference lies solely in the amplification stage, and therefore in the sound character.

Does the AVM Evolution PAS 3.3 have a phono preamp?

Yes, a full-fledged one for MM and MC cartridges. MM amplifies by 40 or 50 dB, MC by 60 or 70 dB. You set the loading resistance and capacitance in the RC X app, without opening the case. A separate phono input is permanently built in for this.

Do I still need a power amp for the PAS 3.3?

Yes. The PAS 3.3 is a pure preamp with no power amp of its own and doesn't drive speakers directly. You run it into a stereo or mono power amp, or into active speakers. We're happy to help you work out which power amp suits your speakers.

Can I connect headphones to the PAS 3.3?

Yes. The PAS 3.3 has its own headphone amp on board, delivering up to 7 V with a 24-ohm output impedance. That brings even high-impedance models up to level. Which headphones suit your taste is something we're happy to discuss by phone or WhatsApp.
