Pre/Power Amplifiers

Nothing if not ambitious, Cambridge Audio's Edge series first broke cover three years back as part of the company's 50th anniversary celebrations. It took its name from Gordon Edge, one of the company's founders and the brains behind its first product, the P40 amplifier. Designed to take on the best in high-end audio, these Edge separates also serve as 'halo' products for the company's lower-tier ranges.

The long awaited Carver Cube power amplifier is at last available in the UK. Bob Carver, its designer, is not a particularly well known figure in the UK but most people have heard of Phase Linear, which was founded by him, and he also designed its range of products. His special interest has been in high-power amplifiers, with the 400 B and 700 B Phase Linear models now audio legends.

We’re all familiar with the idea of ‘trickledown’, where the R&D of a flagship product then informs the development of a brand’s more affordable models. But what we have here, in CH Precision’s L10 preamplifier and M10 power amp, is a case of ‘trickle-up’. The Swiss marque has taken the designs of its 1 Series amplifiers [HFN Sep ’25], with which it carved its high-end reputation, and comprehensively upgraded them to birth a new top-flight package.

Never let it be said that the Chord Electronics range isn't distinctive in its styling: all the way up from the tiny Mojo DAC [HFN Jan '16] to the flagship Ultima reference preamplifier [HFN Feb '19], the company's products look like nothing else on the market, as if to emphasise that what's going on inside them involves no shortage of proprietary technology, too.

When it comes to prosaic model naming, Classé has it nailed: its latest Delta series preamp, selling for £9999, is called 'PRE', and the matching monoblock power amps at £10,999 apiece, are called 'MONO'. The only other model in the lineup is the Delta stereo power amp, at £11,999, which is unsurprisingly called 'STEREO'.
