hfnvintageWith the latest Apogee, ribbon technology comes in a more affordable package. Ken Kessler's assessment follows Martin Colloms' review

The US company Apogee has expanded its range of open-panel loudspeakers, which began with the Apogee model itself. This was a large-scale design using three separate diaphragms, with pure aluminium ribbons for frequencies above a few hundred Hertz. Three other models are now in production, comprising, in descending order of size and price, the Scintilla [HFN Sep '85], Duetta, and now the so-called 'baby' of the group, the £2500 Caliper.

Martin Colloms gets to grips with the new SME Series V

The Series V tonearm is on sale at last, albeit in limited quantities. The fruit of many years of creative research, a handmade prototype 'V' was shown to prospective distributors at the American and German shows two years ago, but it has taken a long time to get the arm into production. Components were continually tried from prospective suppliers until the quality was right and when first shown in 1984, the price was targeted at what was then a very high level, at £750 or so. Some expressed doubts concerning its credibility at that price, indeed of any similarly-priced tonearm.

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).

A year after the launch of CD, Martin Colloms looks at the progress made by player manufacturers before reviewing the new generation of machines

This issue marks the first anniversary of CD's UK launch, the Philips CD100 appearing on these shores in March 1983. There has been some comment in the press concerning a 'second generation' of CD players and this appears to be the case for some manufacturers.

Martin Colloms hears the ultimate amplifier system from one of audio's elite names: the No26/No20.5 pre/power duo and No25 phono stage

Since acquiring the Mark Levinson Audio Systems company five years ago, Madrigal Labs has pursued an evolving research programme, generating improved circuits and product designs. The result is that current MLAS products now have an importance comparable with the original brand's landmark designs.
