About the 150A Version 2
The Belles 150A Reference Version 2 is a Class B stereo power amplifier offering 125Wpc into 8Ω (250Wpc into 4Ω) with dual-mono architecture. Its cascaded differential input stage uses matched J-FET/bipolar transistors, followed by a bipolar voltage-gain stage and eight MOSFETs per channel in the output stage. The amplifier features a shared 1000VA toroidal transformer for enhanced bass performance, achieves a damping factor of 1000, and maintains a signal-to-noise ratio exceeding 100dB. The chassis comes in black or silver finishes (17"W x 5.25"H x 16.5"D) with optional 1/2"-thick faceplates. Reviewers praise its exceptional transparency, spatial presentation, and musical engagement.
