The integrated amplifier market has seen a number of new arrivals of late. We compare six mid-priced models

The variety of formats that people are using as their source equipment to play music shows no signs of resolving itself just at the moment. We currently have plenty of DACs and streamers vying for the top spot, while the CD player battles on – fighting a valiant rear-guard action – and vinyl continues to lure in new initiates in surprisingly increasing numbers. Against this volatility, the integrated amplifier market has been a lot calmer. Although some digital sources are showing ambitions towards input control as they adopt many of the features of a preamplifier, for a great many of us, a hi-fi system will be built around an integrated amplifier that receives your sources and sends the amplified signal on to your speakers.

As befits a relatively stable category, the choice of integrated amplifiers costing between $959.58 and $1,279.44 is impressively substantial and includes offerings from a few brands who only a few years ago appeared to have given up on two-channel models in pursuit of multichannel. All of the models you see here should have sufficient power to work with speakers at a roughly similar price point and all of them offer such niceties as a remote control for the lazier among us and a headphone socket for those personal listening spells. They also all boast a general level of build and finish that is a step up over more entry-level offerings.

After these points of consistency though, things start to get more varied for our sextet. The features on offer are bewildering and only one of the designs here is a straight, line-only amplifier with no additional input features. Of the other five, three are fitted with digital inputs and four of them have phonon stages as standard – one of which even offers the required gain for turntables fitted with a moving coil cartridge.

Feature count

All these bells and whistles count for very little if the amplifier itself doesn’t sound any good, and that’s why, as ever, there’s no substitute for listening to them in carefully controlled conditions. All six are being judged on their ability with a standard line-level signal with their extra features being taken into account once the dust has settled. Is simplicity the way forward for a world-class amplifier or can you build an all-star performer and keep the extra features on? Turn over to find out.
