Part of this comes down to excellent solidity. This is perhaps less well heard on classical guitar (even a big, eight string one), but is clear on ‘The Moon Song’ from Beyond The Missouri Sky [Verve], the late 1990s duet with Pat Metheny and the late, great Charlie Haden on bass. Metheny’s guitar and synth sounds are forward in the mix and it’s easy for Haden’s bass to float around the mix a little. Instead, it’s a rock-solid underpinning. And it’s not just slow jazz where this rootedness benefits; when the band kicks in on ‘She Talks To Angels’ from The Black Crowes Shake Your Money Maker album [Def American] yet again the band is rooted in place, and not just a Stones tribute act.

Let’s put this into perspective. I could improve on the sound of the VSi75 within the Audio Research range, but I would struggle to improve significantly upon its performance from two boxes anywhere near the same price. No, that’s too sanitised. If this were real life, I’d be leaning in and I’d be whispering this; don’t let anyone know, but every fibre says this is Audio Research Reference amplifier combination-grade sonic performance, but with £10,000-£15,000 lopped off the price.

This downshifting lark demands a lot and frequently fails to deliver. It’s 2014; we should be able to take preamp, power supply, power amp, and all the trimmings, put it all in one box and get a performance at least as good as what we previously had (if not better) for less money. And, when you actually sit down and listen to what the Audio Research VSi75 does, it does just that. Yes, of course a Reference 5SE preamplifier with a Reference 75 power amplifier is better, but this isn’t just in the same league, it’s playing in the same game, and it’s not outclassed. Excellent.
