By switching at frequencies up to 1 MHz — far beyond what traditional silicon can achieve — the A1 PRO delivers ultra-clean, full-bandwidth sound with vanishingly low distortion. Whether you are driving a pair of reference stereo speakers or configuring a bridged mono setup for maximum headroom, this amplifier brings benchmark-grade performance to a desktop-friendly footprint.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eGallium Nitride Technology: Faster, Cooler, Cleaner\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eAt the heart of the A1 PRO lies a GaN power stage built around Infineon transistors.

Unlike conventional silicon FETs, GaN devices switch with dramatically less dead time — the micro-moments when both output transistors are momentarily off. This ultra-fast switching virtually eliminates crossover distortion, preserves transient accuracy, and runs cooler, allowing the A1 PRO to deliver substantial output power without a massive heatsink.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eStereo and Mono Flexibility\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe A1 PRO effortlessly adapts to your system.

For those seeking even greater authority, switch to bridged mono mode and unlock 400W into 4Ω (250W into 8Ω). Use a pair of A1 PROs in dual-mono configuration to quadruple your power reserves and drive the most demanding loudspeaker loads with absolute control.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003ePrecision Volume Control with the TI PGA2311\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eVolume adjustment is handled by the Texas Instruments PGA2311, a digitally controlled analog volume chip renowned for its channel matching and vanishingly low THD.

dedicated two-channel systems and flagship headphone stacks. Built around a four-channel reference-grade amplification circuit with a true end-to-end differential design, it pairs a 0.1 dB precision relay volume control, three balanced combo inputs, one pair of XLR balanced outputs, and fully independent digital\/analog power supplies with measured performance of 0.00005% THD+N and 151 dB SNR. A 2.0-inch high-definition color display, touch controls, and a CNC-machined aluminum remote complete a preamplifier that is as pure in form as it is in sound.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eFull-Path Balanced Architecture\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe PRE900 employs a four-channel reference-grade amplification circuit that is fully balanced in every stage — a true end-to-end differential signal path from input to output. Left and right channels are physically isolated to the highest degree, effectively suppressing noise and electromagnetic interference so the signal you feed in emerges exceptionally pure and pristine.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eIndependent Power Supplies\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eDigital and analog circuitry are powered completely independently, eliminating crosstalk at the source.
