Pioneer - M90 Solid state integrated amplifier

This superb Pioneer M-90 is a high-quality stereo power amplifier from the renowned Reference Elite series (also known as the Urushi line). Introduced in the late 1980s, this model stands as a symbol of the golden era of hi-fi, where no compromises were made on build quality and power supply.
The unit uses Pioneer’s Non-Switching Type III circuit, which increases thermal stability and minimizes distortion. The internal construction is almost completely separated (Twin Mono construction) with large transformers and massive capacitors to maintain control even with demanding speakers. Visually, the amplifier stands out with the deep black high-gloss lacquer, wooden side panels, and the distinctive red digital power meters.

APPEARANCE:
Neat condition, no scratches on the front; the top shows some small signs of use.
The wooden side panels appear repainted, but neatly so.

Warranty:
The audio equipment we offer is largely vintage equipment aged 40 years or older. Each unit is carefully inspected by us, professionally cleaned, and extensively tested before being offered for sale.

Despite this careful inspection, it may occur that a defect appears upon receipt or after some time. Due to the age of the equipment, such faults can occur unexpectedly and are unfortunately beyond our control.

For this reason we cannot provide a warranty on vintage equipment. We understand this can be inconvenient and we believe it is important to be transparent and honest about this. Of course, we do our utmost to deliver each unit in as good a condition as possible.
