350A V2

About the 350A V2

The Belles Reference 350A V2 is a compact yet robustly built solid-state stereo power amplifier featuring a dual mono design powered by a single 2000 VA toroidal transformer. It delivers 250 watts per channel into 8 ohms and 500 watts per channel into 4 ohms, with a frequency response extending from 0.2 Hz to 100 kHz and total harmonic distortion under 0.1% at rated power. The amplifier's circuit includes three amplification stages: an input stage with matched dual J-FETs in a cascaded differential pair, a voltage gain stage using bipolar transistors, and a final stage employing a source follower with eight class B biased power MOSFETs. It has a high damping factor of 2000 and an input sensitivity of 1.98 V. The chassis is designed with substantial heat sinking and a simple front power switch. The 350A V2 is praised for its ability to deliver clean, faithful sound with excellent bass grip, instrument separation, and spatial imaging, making it a strong performer especially when paired with complementary components like the VT-01 linestage. It weighs approximately 65 lbs and measures 17" W x 5.25" H x 16.5" D. The amplifier is valued for its combination of power, control, and sonic transparency at a price point of with the option to upgrade to monoblock operation for increased power output.
