Integrated Amplifiers

Back in 1993, Charles Hansen – the designer and founder of respected US loudspeaker specialist Avalon Acoustics – formed Ayre Acoustics. Over the 25 years that followed, he built up the brand, adding a range of innovative preamps, power amplifiers and integrated designs, all descended from the company's original 'zero-negative feedback' V-1 power amplifier. Bolstering the current lineup are various digital sources, such as the Ayre QX-5 Twenty USB/streaming DAC [HFN Dec '17], phono stages, and head-fi products like the Codex DAC/headphone preamp [HFN Jul '16] – all at prices that indicate they're not aimed at the mass market.

Three thoughts hit me as soon as I switched on the Copland CSA100 integrated amplifier. The first was that it was an all-embracing, do-everything tube/transistor hybrid like the Vinnie Rossi L2i-SE [HFN Jul '20], rated at a similar 100W/8ohm if at a fraction of the price, at £3498. The second was that I want it to kick off a fashion for cool, fully-loaded integrated hybrids because they are the smartest option for offering the best of the tube/solid-state worlds. The third is the realisation that I need to look deeper into hi-fi system building.

Arcam is still headquartered in Cambridge, from where it took its original name, but the audiophile marque is now part of Samsung's global consumer electronics empire, through the latter's acquisition of Harman International, which had added Arcam to its portfolio in 2016. And amid these management-level changes, Arcam's product line has also undergone a refresh. The brand has withdrawn, for the time being, from the peripherals market, jettisoning its R series of docks and DACs.

If you are into fancy-looking hi-fi with machined fascias and decorative meters then the £5649 M8xi integrated amplifier is not for you. 'Sorry, that's the way it is', says Musical Fidelity, though I suspect this declaration of intent for the entire M8 series owes more to Musical Fidelity's founder than the new owners, Audio Tuning Vertriebs GmbH, of which vinyl evangelist Pro-Ject Audio Systems is another division.

Hybrid amps have always amused me. I still dream of Radford's TT100. This hi-fi equivalent of grafting two plant species hopes – ideally – to combine the best of a brace of disparate technologies. Too often, they marry the worst. Extraudio's X250T represents a first for me in that it promises to take efficient, compact Class D amplification and endow it with the sonic virtues of Class A, hence Class AD. Which made me think of playing with Krells way back in 1985.

As the latest in a long line of amplifiers from the German brand, T+A's PA 1100 E integrated is also one of the more innovative and comprehensive in its scope. The company (T+A stands for 'Theory and Application') has been manufacturing audio equipment since 1978 and prides itself on both its deep technical capability and in-house manufacturing. However, despite this heritage, the PA 1100 E is only the first of its amplifiers to include an onboard DAC – something very many competing brands have been doing for years.
