Choosing an amplifier is less about chasing one headline specification and more about selecting the right control centre for the system you actually want to build.
The products here cover several roles: preamplifiers with network features, integrated amplifiers, multichannel and stereo power amplifiers, monoblocks, and even active speakers with amplification built in.
1. Premiera X1S PRO: High-quality preamplifier with a built-in network player
Premiera X1S PRO preamplifier with front-panel controls, display and network playback capability.
The Premiera X1S PRO suits systems that need a modern preamplifier to handle both source management and digital playback.
Its source count, built-in network player, MM/MC phono stage, DAC, Bluetooth, Wi-Fi, AirPlay 2 and HDMI ARC make it unusually broad in function, while balanced and unbalanced adjustable outputs allow it to feed a power amplifier directly.
Best for: Feature-rich stereo preamp hub
- Built-in network player and DAC
- MM/MC phono preamplifier
- HDMI ARC, Wi-Fi and AirPlay 2
- Balanced and unbalanced adjustable outputs
Verdict: A practical preamplifier for listeners who want extensive source handling before choosing their preferred power amplifier.

3. JBL 4305P: Active bookshelf speakers with with built-in streamer
JBL 4305P active bookshelf speakers with horn-loaded tweeter, woofer and built-in electronics.
The JBL 4305P is not a standalone amplifier, but it earns a place here because amplification, DAC processing and streaming are built directly into the active speaker system.
Each speaker uses separate Class D amplification for the tweeter and woofer, with digital, analogue, wireless and network input options for a compact system that reduces the need for external boxes.
Best for: Minimalist active speaker systems
- Built-in Class D amplification
- Onboard DAC up to 24-bit/192 kHz
- Ethernet, USB, optical and analogue inputs

How to choose from this amplifier shortlist
Start with the job the component must do.
If you need system control rather than speaker drive, the Premiera X1S PRO and Accuphase C-3900S are preamplifiers and must be partnered with suitable power amplification.
If you want one main stereo box, the Luxman L-505Z, Cary Audio DMS-300A and Simaudio MOON 641 are integrated amplifiers, with the Cary adding streaming as a central part of its appeal. For existing preamp-based systems, focus on the power-amplifier options. The Ultrafide Audio SP500 is the compact stereo choice, the Mark Levinson N 5302 offers bridgeable dual-monaural Class AB architecture, and the Merrill Audio ELEMENT 110 is the monoblock route. Home-theater builders should look most closely at the Tonewinner AD-5100PA+ because its five channels are directly suited to multichannel speaker layouts. The outlier is the JBL 4305P, which replaces the usual amplifier-and-speaker split with an active speaker system. It is the simplest path here for a compact setup, but it is also the least appropriate if you specifically want to choose separate passive speakers and amplifier electronics. Match the amplifier format to the system first, then weigh connectivity, output needs and source handling.
