Review: Andrew Everard

Time, it seems, to forget all the stereotypes of high-output power amplifiers as massive devices that dim the lights when fired up and convert even the chilliest of spaces into a listening-room sauna. Instead, the £7299 Perca stereo power amp from Dutch manufacturer Mola Mola is just 215mm wide and 110mm tall, and weighs a mere 5.25kg, yet claims a stereo output of 150W/8ohm, doubling to 300W/4ohm.

Debuted at the UK Hi-Fi Show Live 24, Audio Research’s new flagship monoblocks are not quite its most powerful ever, but are the first to feature the mighty KT170 output tubes

The latest arrival from US high-end brand Audio Research Corp., the Reference 330M monoblock amplifier (£92,000 per pair) may not quite be the most powerful amp the company has ever built, but by any standards a rated output of 330W – into 4ohm or 8ohm speaker loads – is going some for an amplifier using tube technology. Indeed, it will come as something of an eye-opener for those still subscribing to the belief that for the purity of the valve sound – or whatever else you consider to be the sonic traits of the genre – you must settle for low output power, and start looking for speakers of appropriately high sensitivity.

Compact yet highly capable, the DAC204 may look like a simple USB device, but within is a host of its Swiss manufacturer’s focused engineering and precision construction

Today’s digital audio world, having largely switched from the playback of physical media to files stored on computer drives or streamed from the Internet, seems populated by products of ever-greater complexity. They may still be DACs, but they have built-in network streaming interfaces and often volume and preamp functions so they can drive power amps, or active speakers, directly. Sometimes they do all that and more, thanks to Bluetooth, Chromecast and even integrated voice control.
