Overview

Studio‑Level Two‑Channel Power in a Compact Rack

Drop the NC 275v2 into your system and the whole presentation tightens up—voices lock center‑stage, bass digs deep without bloat, and big moments stay calm, clear, and composed.

In just 1U, it delivers 90 W x2 into 8 Ω (150 W x2 into 4/2 Ω) or 200 W bridged mono. A fully discrete Class‑AB design with a high‑current toroidal transformer supplies clean current, while a switchable 20/40 Hz high‑pass filter and dual A/B speaker outputs make real‑world setups easy.

Praised by reviewers

  • Most satisfying, though, is the extreme sound quality this Bay Area team manages to extract from some of the most modest of physical profiles. The New Classic 275 v.2 is no exception to the rule. Stack two of these skinny slabs in your rack for Atmos flyovers, or plonk it on your desk with a streamer for a highly rewarding bask in your jazz collection. I don't think you will be disappointed.
