From the Vault

True story: a knowledgeable audiophile arrives at my listening room in mid-November. Pink Triangle’s Integral integrated amplifier is driving a set of Wharfedale Diamond 8.1s, its badge covered with tape. I state to this collector of some repute with a memory spanning 35 years, ‘You will never guess who made this amplifier. Never’.

Much gnashing of teeth and wringing of corporate cheque books later, and the B&W Group has become the latest recipient of Philips’ cherished Red Book licence: an exorbitant magic wand that bequeaths the rights to design and assemble own-brand CD players, rather than simply modify an existing box. Incidentally, I hear from trusted sources that manufacturers who have traditionally opted for this cheaper halfway-house will soon be stomped on from a great height. B&W can therefore sleep soundly at night as two variants of a new BitStream player are launched under its ‘Aura’ brandname.

If the market for two-box CD transport/outboard DAC combinations has waned in recent years, then the same cannot be said for those little black boxes conceived to nestle in between. I refer, of course, to the add-on accessories often rather optimistically promoted as 'Jitter Busters'. Typically, these rely on a Crystal interface chip and one or two PLLs to suppress jitter while recovering the data clock.

It was back in the March 1996 issue of Hi-Fi News that I took my first look at the £6250 Stratosphere ST1 – a turntable that proved out of this world in sound quality as well as name. Now John Jeffries of Reference International (the name behind both the Strat and Lumley) has delivered a complete system including the £4500 LM2 loudspeakers.

Sitting in a neat stack on the desk in front of me as I write, the subjects of this review remind me of those pretty Toshiba Aurex units of yesteryear [HFN Apr '16]. There are three Micromega components in all: the Microdrive CD transport (an improbably small device, this); the Variodac, comprising a Bitstream digital-to-analogue converter with remote power volume control and an additional line input; and finally, the Microamp, a neat-looking stereo power amplifier block.

In the late 1980s and early 1990s, the audio underground in the US and Europe finally picked up on the efforts of Japanese audiophiles two decades earlier, and started a revival of single-ended triode amplification. The American interest really got going when enthusiasts started salvaging dusty pre-war systems out of old movie houses. Western Electric's 300B triode, dating back to the dawn of cinema sound systems, became the tube of choice.

When they weren't playing, I found the appearance of these loudspeakers to be disconcerting because their normally exposed electrostatic elements are shrouded in a black cloth hood to keep out the dust. But when the cloth is removed, and the elements are exposed for use, their silvery perforated stator elements are presented in striking full view.
