hfnvintageTiny amp, lashings of power... Martin Colloms lifts the lid on a box of tricks

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.

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.

hfnvintageThis slim design offers the traditional benefits of transmission line bass loading yet manages to overcome the drawbacks, says Martin Colloms

New ideas are being introduced at Celestion to bring its upmarket SL series into the 1990s. The first example, designed by Bob Smith, was the 100 [HFN Nov '91] followed now by the 300 reviewed here. This is a £1000 floorstander that aims to bring improved bass extension, power handling and superior dynamics to the genre, while sensitivity remains below average at 84dB/1W. A remarkable aspect of the 300 is its transmission line loading, a first for Celestion, and developed with an unusually authoritative theoretical approach, by the designer Martin Roberts.

An acoustic ribbon hybrid loudspeaker at a realistic price without the need for a huge amplifier. Too good to be true? Ken Kessler finds out...

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.

Trevor Attewell examines a trend-setting loudspeaker from Ipswich

It is no exaggeration to state that the SL6 is one of the most interesting moving-coil speakers to come my way for a long time, and that it embodies significant advances in driver design. Many readers may find this surprising. After all, Celestion has traditionally been associated with the mass end of the market, its reputation justifiably built on product consistency and value-for-money rather than on innovation.

John Atkinson reports on the 1980 summer Consumer Electronics Show

Thought highly of by many, the Canadian 'Oracle' turntable is winning a reputation as perhaps the first design to supersede the performance of Linn's respected Sondek. Beautifully engineered, the rigid laminated subchassis arm mount is hung from three springs, which can be adjusted from above.

hfnvintageKen Kessler goes Class A in a small way with the Marantz PM-4

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.

hfnvintageMartin Colloms shows some ART appreciation as the US company celebrates 30 years with a statement single-ended line-only preamp

Conrad-Johnson's 'Anniversary Reference Triode' has been some time in the making. In fact, an early version was developed seven years ago which has since been used as a lab reference. The ART is simply a remote-controlled line preamplifier, which at £15,000 is priced far beyond any previous Conrad-Johnson offering in this sector. It will be made in a limited edition of just 250 – probably just right for a modest production run at this elevated price level.

hfnvintageWhat could match a Lumley Stratosphere turntable better than Lumley’s LM2 speakers and PS2/M250 pre/power amps, says Peter J Comeau

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.

hfnvintageDoes enormous power always make musical sense? Martin Colloms hears a new stereo power amp from a designer who begs to differ

DNM's long-awaited update to the PA3 power amplifier has finally arrived. Fully regulated, the PA3 S reflects the uncompromising approach of its designer Denis Morecroft. Offering just 23W per channel but costing £3750, this stereo power amp has undergone a long gestation, the reasons for which Morecroft outlines in our interview boxout.

hfnvintageMartin Colloms hears two outboard DACs featuring 20-bit chips in custom circuits – Enlightened Audio Designs' DSP7000 and the PS Audio Ultralink

American specialists, like their UK counterparts, continue to develop new variations on the available digital technology to produce DACs with audiophile appeal. This review covers two of the more intriguing examples, using some of the most advanced devices available to designers. The Enlightened Audio Designs DSP7000 is based on the 20-bit Analog Devices chip, while PS Audio has chosen an Ultra Analog dual 20-bit converter. What bearing the two choices of technology will have on sound quality remains to be seen!

hfnvintageNaim Audio at last offers a CD player, but how does the CDS compare with its rival from Linn, wonder Christopher Breunig and Steve Harris

My patience was put to the test with the Naim CDS. As I unpacked the two units and coupled them together I experienced a flush of old 'brand loyalty'. Since the days of the original 12S preamp and NAP160 power amp, my meetings with company founder Julian Vereker had been cordial and I had spent several pleasurable years with my NAP250. My frustration came with the waiting time for the player to warm up before listening began.

Some costly 'jitter-busters' are less than successful at cleaning up the digits, so can this one justify its high price tag? Paul Miller crunches the numbers...

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.

hfnvintageOrtofon's SPU cartridge has reappeared. Ken Kessler gives it a whirl

Paranoia is not a condition to which I subscribed prior to entering the brotherhood of audio writers. Ignorant of my near-leper status, it came as something of a shock to find myself the only valve-loving, moving-magnet cartridge supporter in the immediate vicinity. Thankfully, editor John Atkinson tends to offer advice and make suggestions, rather than threaten my physical well-being for failing to embrace the solid-state, and so decided that a review of a moving-coil cartridge would be a subtle way of sowing the seeds for my conversion. And he knows my weaknesses well: anachrophilia.

hfnvintageHere's an amplifier that doesn't just look different, it's different through and through. Ken Kessler hears a potent powerhouse from Down Under

There are two piles of magazines, some 150cm tall, sitting in my lounge. They consist mainly of hi-fi titles that I can't read until they're 'out of date'. Why? Because I don't want to be influenced by the reviews, and I don't always know whether or not I'll be reviewing a component I've just seen slammed or praised. Thus it was that I tried to avoid whispers about the Halcro amplifiers from Australia. Even so, I kept hearing about these 'amazing amps' from all and sundry.
