From the Vault

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.

Hybrids are supposed to be the best of two or more technologies, and we've seen the approach used for all manner of products. The most feverish of hi-fi's Dr Frankensteins though, have always been devoted to loudspeakers.

For the past four years, I've been waiting impatiently for a stab at the electronics from Air Tight. I admit that the charm of the name, the absolute perfection of that moniker for a brand of valve amplifiers, caught my attention as much as did the obviously exquisite manufacture. The price, too, appealed, considering that these amplifiers promised peerless construction and attention to detail you just don't find this side west of a Jadis. At last there's a UK importer, so my wait is over.

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.

Streetwise. Now there's a word. I suppose you could say that in a hi-fi context it means being aware of the unwritten myths, such as 'image depth is due to microphony in valve amplifiers' or 'Class A amplifiers sound better than ones operating in Class B' or 'the only truly great preamplifiers use valves'.

By 1985 standards, preamps selling for between £500 and £1000 are thought of as 'upper mid-fi' and not really expected to match the standards of the Krell PAM-3/Audio Research SP-10 variety. But they should bring you close enough to the state-of-the-art that you have to think long and hard about justifying an expenditure of double their prices – or even more. Aah, diminishing returns...

Phone calls from company spokespersons such as Marantz's Steve Harris, are generally one of two types. Either 'Would you like to review our new Model XYZ whatever?' or 'Where the hell is our Model XYZ whatever, which you've had for nine months?' Such phone calls are never about reviewing components that are out of production.
