Sugden Masterclass SPA-4 Stereo Power Amplifier

$10,425.00 CAD

The Sugden Masterclass SPA-4 is a pure Class A stereo power amplifier derived from the MPA-4 monoblock design. It delivers 75 watts per channel into 4 ohms and accepts both single-ended and balanced inputs.

A single pair of multi-way locking binding posts is provided for each channel. The one-chassis format is intended to offer Masterclass power-amplifier performance where a pair of monoblocks is not practical.

Custom finishes: Titanium and Graphite are the standard finishes. Custom colours are available by special order at additional cost. Please contact us to discuss available colours, pricing and lead time.
