Martin Colloms takes a listen to four new designs costing £250 plus

Following last month's batch of integrated amplifiers costing under the £200 mark, more advanced models have been chosen for this project. The new Mission 778 (Mission Cambridge) represents the UK contribution (£240). The Harman Kardon PM650 combines Japanese and American design (£250), while the European contender is the Revox B251 (£900 plus £45 for the remote controller). All three models are integrated amps with MC and MM input facilities. I also look at another new UK model, the powerhouse P128 from Sugden, which is a dual 'monoblock' power amp (£395).

It used to be said that the only true way to learn was to find out something for yourself, then it will stick when all book-learning has long since been shed. This was drummed into me when I was working on the development of LEDs (green ones, to be precise).

These new products from A&R Cambridge have been long in the pipeline. In an unusually brave step for such a small company, it has invested in moulding tooling for the front panels and also the casework of the preamplifier. Its aim was to achieve close tolerances, and considerable effort has been expended in achieving a good fit of parts, particularly for the array of controls on the preamplifier.

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.
