Exposure 3510 Stereo Power Amplifier
The Exposure 3510 Stereo Power Amplifier is a British-made, Class A/B design that delivers 110W per channel at 1kHz into 8 Ohms. It is a straightforward power amplifier - no volume control, no input switching, just amplification of the incoming signal. It was positioned as a natural bi-amping partner for the 3510 Integrated Amplifier, and dealers noted it was designed to simplify bi-wiring setups. The original UK price appears to have been £1,590, per Hi-Fi News, though one pre-owned listing cites an original price of £2,400.
Specification-wise, the 3510 Stereo Power Amplifier offers a frequency response of 20Hz–20kHz ±0.5dB. The distortion figures vary by source: one dealer lists <0.015% at rated output, while another specifies <0.01% @ 1kHz referenced to rated power. Given the conflict, treat either as approximate. The unit weighs 12kg net (14kg gross) and measures 115mm x 440mm x 300mm. It draws under 400W into an 8-Ohm load with both channels driven, and uses a T4AL fuse on 220/240V units. Internally, it features a high-capacity custom toroidal transformer and high-quality capacitors in the signal path.
Beyond a listing at a handful of dealers, little is documented about this model. The VTA archive dates the related 3510 integrated amplifier to 2005 and notes the series represents "updated versions of classic models" blending vintage design philosophy with modern refinements. No production years are confirmed for the stereo power amplifier itself. No S/N ratio, damping factor, or input sensitivity figures have surfaced, and no dedicated period reviews of the stereo power amp alone have been located. What exists is a dealer-level record of a well-built British power amp from a respected brand, intended to pair with its integrated sibling.
