Review: Adam Smith

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.

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'.

None of us needs reminding that the enthusiasm for vinyl continues apace. Yet while manufacturers of turntables and tonearms were quick to serve this revitalised market, makers of pick-ups have taken a little while longer to catch up.

In these evolving days of digital music, cloud storage and online streaming, it might seem counter-intuitive for Musical Fidelity to release a line-only amplifier and 'plain vanilla' CD player. The £799 M2si integrated has no inbuilt DAC, no Bluetooth, no Wi-Fi and not even a phono stage, or indeed the option of one. And, peer round the rear of the matching £799 M2scd compact disc player, and the only connections you will find are outputs. Once again, it has no digital inputs, no antennae sticking out and no wireless wizardry up its sleeve. What's going on?
