It has been constructed with premium parts, including metal film resistors and film capacitors, reinforcing Usher’s reputation for high-quality manufacturing. High-power bipolar transistors, designed by Motorola, can handle sophisticated power and current requirements. And its massive AC power transformer works with a high-capacitive filtering system for the purest sound. Other features include Burrow-Brown OPA2134P Sond Plus Series op amps, bridging switch for mono block operation, terminals that accept both banana plugs and spades, optional balanced inputs and large handles on the front and rear panel.

It is designed to provide high power output with very low distortion for Primare’s SP33 audiophile preamp/processor and all other multi-channel audio processors. UFPD’s instantaneous rise time and prodigious power result in a naturally fast, clean and agile sound over a much wider frequency range and with exceptional headroom. Ecologically the A30.7 is far superior to conventional Class A/B designs being extremely efficient without generating excessive heat.

With the 60 series components, Primare reclaims its presence in the high-end music system market, reprising the iconic designs of previous decades with ravishing new separates, complete with state-of-the-art audio streaming performance and striking two-tone bodywork. By combining our traditional build quality and analogue circuit design with the finest digital processing, the first 60 series music system represents a major step-up from the 30 series and introduces a new supremely audiophile level of performance to our product range.

The A60 is designed to provide high power output with very low distortion for our PRE60, as well as multi-channel audio processors. UFPD’s instantaneous rise time results in a naturally fast, clean and agile sound over a much wider frequency range and with exceptional headroom. Ecologically the A60 is far superior to conventional Class A/B designs being extremely efficient without generating excessive heat.

This is a massive fully balanced design capable of controlling the most demanding low-sensitivity speakers - even at the very highest volume levels. The specification is impressive. Equipped with a 2kVa toroidal transformer featuring four separate windings, two for each (L/R) channel; a reservoir of 90.000 uF and sixteen bipolar output devices per channel, the A32 is undeniably an elite amplifier in the classic Primare dual/mono mould. Both balanced and unbalanced inputs are provided, as well as twin speaker terminals for bi-wiring, a trigger input and RS232C inputs. If the unbalanced inputs are used the A32 converts the signal to balanced, to take full advantage of its balanced design.
