Description
The Musical Fidelity A3.5 is a highly regarded dual-mono integrated amplifier known for its muscular power delivery, refined British sound signature, and exceptional control over difficult speaker loads. it features a distinctive satin aluminum faceplate with a massive centered steel volume knob.
Key Specifications
Power Output: 150 Watts per channel into 8 Ohms and 240 Watts per channel into 4 Ohms.
Current Delivery: Peak-to-peak 50 Amps, allowing it to effortlessly drive "current-hungry" speakers.
Internal Architecture: True dual-mono circuitry running off a single, massive toroidal transformer to achieve zero channel crosstalk and excellent stereo separation.
Connectivity: 5 Line-level RCA inputs, a Pre-Out (to add an external power amplifier), and a dedicated Tape loop.
Home Theater (HT) Bypass: Includes a specialized input that routes signals directly to the power amp section, allowing seamless integration with an Audio/Video Receiver (AVR).
Sound Signature & Performance
Dynamic and Balanced: Unlike some of Musical Fidelity's later entry-level lines (such as the M3i) which can lean bright, the A3.5 is praised for being sonically balanced and forgiving.
Muscular Low-End: It acts as a proper power partner for demanding floor-standing speakers, delivering tight bass control, transparent midrange definition, and a full-bodied soundstage.
No Built-In Phono: Unlike its predecessor (the A3.2), the A3.5 does not feature an internal phono stage; connecting a turntable requires an external phono preamplifier plugged into one of its auxiliary line inputs.
