Integrated Amplifiers

Launched last year, NAD's M10 all-in-one streaming system [HFN Jun '19] was remarkable in two ways. One was that this compact 'just add speakers' package was actually part of the brand's elite Masters Series, more usually populated by high-end DACs and amplifiers, while the other was that this little system, selling for around £2000, was exceptionally good, receiving a glowing review in HFN before going on to win a 2019-20 EISA award as Best Smart Amplifier.

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'.

Is Editor PM simply testing me, or coaxing me? I'm not merely uninterested in streaming, Wi-Fi, et al to the point of virulent loathing, I'm actually reverting to decades-old formats for daily listening: CDs, tapes and LPs. That said, I am not unaware of DTS Play-F, having used it for many months for the wireless speakers on my kitchen counter – though with no more concern than I show a spatula or potato peeler. Yet here I am faced with Quad's update to the Vena II, its entire raison d'être being the full-on wireless experience.

Each of Sound United's two mainstream hi-fi brands – Denon and Marantz – has its own take on compact, room-friendly separates. In the case of Marantz, it's a lineup comprising an integrated amp and a USB DAC/headphone amp, each styled in 'retro' casework designed to evoke memories of Marantz amps of the past.

Philips should have been a dominant player in the hi-fi arena, yet many of its products somehow missed the mark. Despite these repeated failures, every now and again the sleeping giant would wake from its slumbers and produce something miraculous – Compact Disc, Motional Feedback speakers – only to disappear until inspiration struck again.

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.
