$10,795.00 CAD

The Sugden Masterclass IA-4 is a pure Class A integrated amplifier delivering 33 watts per channel into 8 ohms. Its inputs include three line-level sources, tape, balanced line and an integrated moving-magnet phono stage.

A variable preamplifier output, fixed output and loudspeaker output support system expansion and recording. Relay switching, gold-plated circuit boards and remote volume control complete the design.

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.

Mike’s Pick

Why I love it

The IA-4 brings the scale and refinement of Sugden's Masterclass separates into a single, beautifully focused amplifier. The built-in phono stage and balanced input make it genuinely complete, while its 33 Class A watts invite careful system matching rather than chasing power figures for their own sake.
