Integrated Amplifiers

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.

You need to do some serious rethinking on first encountering the Krell K-300i. If you're expecting a simple device all about massive power and minimalism, you're going to be disappointed, but for those looking for an amp able to handle all the needs of the modern music listener, this one could just be bang on the money.

No-one could ever accuse NAD of lacking ambition. Alongside its acclaimed core range, on which the company has built its reputation over the past four decades, it also has its Masters series of high-end components, several of which have been reviewed favourably in these pages in the past, including the EISA Award-winning M32 integrated amp – sorry, 'DirectDigital DAC/Amplifier' – [HFN Jul '18].
