Integrated Amplifiers

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.

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.

Based in Treviso, Italy, Unison Research has long specialised in making very traditional looking tube amps with polished wooden chassis and rows of glowing bottles on display. At the same time its Unico series has adopted a more mainstream aesthetic and includes valve-based amplifiers that, well, don't really seem like valve amplifiers. Despite an outward appearance suggesting a completely conventional integrated amp, the Due – which sells for £2500 in standard silver with black available at a £100 premium – is very definitely a valve amp, or at least half of one.

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'.

Big, bold and unashamedly old-school with its silver finish – black is available as an option – polished piano black side panels and large illuminated meters, the £4999 Yamaha A-S3200 is the flagship of the brand's integrated amplifier range, which kicks off with the modest £200 A-S201.
