New, this was a serious 4-zone installation amplifier: 8 channels at 100W into 4Ω, with ICEpower-based Class-D amplification, though current replacement pricing is far above the used market. At £350, however, this example is ambitious: the comparable median is £225, with 75% listed at £300 or less. Paying more than that for only two working channels is difficult to justify unless the fault is fully diagnosed and repairable.
There is still worthwhile hardware here for a multi-room or project system. It offers independent stereo zones, global-input linking, bridging options, trigger/audio-sense control, and cool-running operation—useful features in a rack installation. But four of eight channels working makes this effectively a part-unit, not a functioning four-zone amplifier. I’d want clear testing of the two good channels, confirmation that the fault is isolated rather than power-supply related, and included Phoenix connectors before considering it; nearer £150–£200 would better reflect the risk.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.

The brand's product portfolio centers on architectural and custom installation speakers, encompassing in-wall, in-ceiling, in-room, and on-wall loudspeaker designs tailored for residential applications. Triad has expanded significantly in recent years, introducing amplifiers, home cinema speakers, and subwoofers alongside its core speaker offerings.

Triad occupies a luxury tier of the audio market, distinguished by its emphasis on design aesthetics, sonic performance, and customer service. The brand targets custom integrators and discerning residential clients seeking premium, visually integrated audio solutions rather than traditional component-based systems. Its hand-built manufacturing process, American production, and focus on bespoke customization reinforce its positioning as a high-end boutique manufacturer rather than a mass-market player, appealing to audiophiles and integrators who prioritize craftsmanship and tailored solutions.
