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.

When the grapevine alerted the world's tube crazies to the return of Rogers amplification, visions of two-tone faceplates danced before our eyes. A nice Cadet III [HFN May '13], or maybe an HG88 visually unchanged but suitably modernised. The collector in me rejoiced. But the Rogers beancounters felt that an all-new product was a more sensible proposition, which is why the E-20a and E-40a all-valve integrated amps have nothing whatsoever to do with the preceding models. Indeed, they have little to do with Rogers.

Released in 1977, B&O's Beomaster 2400 receiver brought touch-sensitive operation and full remote control to a world that expected nothing more from its hi-fi components than knobs and buttons. Its impact was immense, and soon the company's factory was unable to make receivers fast enough to satisfy demand. What's more, the unit's basic form and function lived on through a series of models that remained in production until 1992. And even by then, the design still looked fresh and modern.

The single-ended valve amplifier is still something of a niche product. Low power outputs and often equally low damping factors mean that very careful system matching, plus sensitive loudspeakers, are a prerequisite if you are to hear such designs give of their very best. However, the UK's very own guru of all things thermionic, David Shaw of Icon Audio, has decided to address these issues with his £2299 single-ended Stereo ST30SE, an integrated amp having, shall we say, a tad more welly, thanks to it being equipped with KT150 output valves.

Something is afoot in the land of hi-fi separates. First we had Musical Fidelity with its M2scd/M2si [HFN Jul '19], then Cambridge Audio's AXC35/AXA35 [HFN Sep '19] and now Rotel has launched its own affordable amplifier and CD player pairing, in the form of the £429 CD11 and £599 A11.

Whether a car, hi-fi component or a general electronic gadget, the promise of 'trickle-down' technology from a flagship model is always an alluring prospect. Cambridge Audio is the latest to claim such an advantage, with the assertion that its new AX models 'take design and innovation cues from the CX and Edge [HFN Nov '18] hi-fi ranges'.

Although many aspire to grabbing themselves a chunk of American high-end audio, there's all too often a problem – price. It's very tempting to look at the price-tags back home in the States and shake one's head at the UK ticket. But most of us can guess at the differences between the US and UK markets, the import taxes and costs involved in shipping and distributing small samples of heavyweight equipment.
