Integrated Amplifiers

Conceived as the ‘command centre’ of a modern high-end system, T+A’s powerful all-in-one system embraces CD and streamed audio, in all its flavours, and radio too...

Looking for a simple, no-frills, ‘straight wire with gain’ amplification solution? If so, it’s a case of ‘move right along, please – nothing to see here’, for T+A’s R 2500 R, available in black or silver at £12,905, is a prime example of large-scale integration in the quest for one of those ‘just add speakers’ systems. Yes, you could connect other source components to it, thanks to a choice of analogue and digital inputs – but really, why would you want to?

Flying in the face of received hi-fi wisdom that presumes absolute sonic purity is best achieved with separate pre/power amplifiers, integrated amplifiers are having something of a renaissance. Aside from the entry-level and mid-market, where one-box amplification has always been the go-to choice, there’s now a good selection of high-end models from the likes of Rotel’s Michi X3 S2 [HFN Jan ’24], starting from just under £6000, to the massive Dan D’Agostino Momentum MxV [also HFN Jan ’24], yours for just short of £100k when fully loaded with DAC and phono modules.

As far-fetched as this may seem, given that most post-Millennials have yet to embrace hi-fi, we are living in another audio 'Golden Age'. This isn't the place to rattle off a list of gems that have crossed my path just since the Covid moratorium ended, but the Western Electric WE-91B [HFN Feb '23], a trio of DeVore speakers [HFN Apr '21, Mar & Aug '23], and family of DS Audio optical cartridges [HFN Oct '21 & Oct '23] are among the many that beg my repeating of the homily, 'You've never had it so good'. Trafomatic's Rhapsody (M2-15 Anniversary stereo PSE 300B tube) integrated amplifier joins them, and emphatically so.

Hailing from Treviso in northeast Italy, Unison Research is a brand with an obvious love of tubes, to the point that you half expect to find a hot bottle or two incorporated in its Malibran and Max loudspeakers. Its CD players, the Unico CD Uno and Due [HFN May ’16], have tube-based output stages, while the solid-state amps in the same series have tube-based inputs. But the company is best known for its all-tube amplifiers, of which there are 15 spread across integrated, pre and power ranges.

While not a household name in the UK, the Warsaw-based Unitra brand caused quite a stir in its native Poland when revived in 2021. Its storied past played a role in this, but so did the reimagined products themselves, thanks to their nostalgia-inducing 1970s aesthetic. Moreover, while the new Unitra designs are predictably more up-to-date under the hood, they sport some idiosyncratic features. The monochrome E ink display of the CSH-801 CD player is an illustration of this, as are the remote-actuated lever switches on the £4499 WSH-805 auditioned here.

So overwhelming is the matter of choice when putting together a system that it can cause as much anguish as pose a fun challenge. What type of speakers? MM or MC pick-up? Integrated or separates? These usually sort themselves out due to space or budget, but 'tubes versus transistors' almost calls for a leap of faith – unlike 'digital versus analogue' because most enthusiasts can manage two sources. The valve/solid-state conflict, though, may find a cure in the Vinnie Rossi L2i-SE integrated amplifier, the 'SE' standing for 'Signature Edition'.
