Primaluna Dialogue Two (£1999)

Ken Kessler & Paul Miller | Jul 06, 2009

Having played with a number of PrimaLuna ProLogue products, I’m safe in saying that each and every one represents astonishing value because 1) they’re made in China, but 2) to European standards. They single-handedly established and provided credibility for the lower entry-level price point for rock-solid valve products, and showed that China was ready to compete with the rest of the world in hardware manufacture, if the proper structure was applied. With DiaLogue, PrimaLuna is attacking the next price point, with the same vigour. That in itself should be enough to make the DiaLogue Two a fascinating prospect for those with up to £2000 to spend on amplification.

Denon Avc A1hd (£3800)

Richard Stevenson & Paul Miller | Jul 06, 2009

With HD technology and disc formats now on a firmer footing, almost every maker worth its transistors has launched a range-topping ‘HD’ amplifier. Enter Denon’s AVC-A1HD, goodbye AVC-A1XVA. Price-wise, the AVC-A1HD amplifier’s £3800 ticket nestles between Denon’s flagship AVR-4308 receiver (£2000, HFN, Dec ’07) and its new £10,000 A1HD multichannel pre/power combination. But of far more relevance is its position against its only serious competition – Yamaha’s DSP-Z11 (HFN, Apr ’08) and Pioneer’s SC-LX90, both at £5000.

Arcam Avr600 (£3500)

Richard Stevenson & Paul Miller | Jul 06, 2009

I always get a warm, Sunday afternoon feeling when a new product arrives from Arcam. While you can imagine the Far Eastern competition frenetically working 24/7 to be first to market with the latest multichannel widget, I see Arcam as a little more reserved, a little more British. The AVR600 may have been a long time coming with its HD-audio decoding, multi-room installer features and premium video processing but it simply exudes dedication and polish from the moment you open the box. It’s substantial for starters.

Darttzeel Cth 8550 (£16,500 Line Only)

Keith Howard & Paul Miller | Jul 06, 2009

This way madness lies. Or so you’d think if you buy hook, line and sinker into the mythology that has grown up around the Swiss darTZeel brand. And yet our Movers & Shakers feature in the March ’09 issue illustrated that darTZeel partners Hervé Delétraz and Serge Roch are nothing if not methodical in their approach to amplifier design. Their goal is to keep the audio path as straight and simple as possible, avoiding input/output switching and even using an optically-coupled rotary encoder for volume rather than a conventional potentiometer.

Yamaha Dsp Z11 (£4999)

Richard Stevenson & Paul Miller | Apr 06, 2009

Yamaha’s Z11 is an amplifier of extremes. Almost every feature can be prefixed with terms like ‘most’, ‘advanced’ and ‘leading’ and the fit and finish is superb. The specification sheet is impressive and the features list is the size of the Encyclopaedia Britannica and reads like my very own wishlist of AV technology. The Z11 is right at the cutting edge of multichannel audio, HD video and multi-room technology and then goes on to incorporate a level of audiophile engineering that would compete favourably with high-end two-channel components.

Rotel Rsx 1560 Hd Av Receiver (£1850)

Richard Stevenson & Paul Miller | Apr 06, 2009

After 45 years in business Rotel has every right to do things its own way. The new RSX-1560 gloriously raises its middle knob to the herd, eschewing games of specification trumps and symphony-length features lists. It is also thoroughly gorgeous to behold, and you can’t say that about many of today’s AV receivers. The clean fascia, sturdy case and chunky polished corner pieces give it high-end panache while the rear panel is a cornucopia of beautifully crafted gold plated terminals.

Nad T765 (£1200)

Richard Stevenson & Paul Miller | Feb 06, 2009

I have a fondness for NAD. The brand has succeeded over the decades by creating products just a few degrees askew from those of everyone else; never following the herd but, equally, rarely radical. In two-channel audio this has often meant a stripped-down, fundamentalist approach with products having an appealing Bohemian quality. However, when it comes to multichannel AV, eschewing key technologies in favour of a ‘music-first’ approach could be a little too existential for its own good.

Krell S 300i (£2400)

Ken Kessler & Paul Miller | Feb 06, 2009

Debate that’s been raging since the dawn of hi-fi, Integrated vs Separates boils down to this: the former’s benefits over the latter include the removal of a pre-to-power cable connection, the need for one less AC outlet, less shelf space and – above all – the knowledge that the two sections are optimised for each other. Separates, however, counter with truly dedicated power supplies for each section, as well as isolation of the pre and power amp stages for less potential for undesirable interaction. Traditionally, the higher you go up the price scale, the more likely you are to opt for separates. Over the decades, milestone integrateds would appear that upset the formula: Sugden’s A48, specific models from Rogers, McIntosh, AR, et al.

Rogers Returns

Ken Kessler | Mar 31, 2020 | First Published: Mar 01, 1996

The loudspeaker firm, famed for its late-1950s amps, makes a late-1990s return to tube electronics with two new integrateds. Ken Kessler listens

When the grapevine alerted the world's tube crazies to the return of Rogers amplification, visions of two-tone faceplates danced before our eyes. A nice Cadet III [HFN May '13], or maybe an HG88 visually unchanged but suitably modernised. The collector in me rejoiced. But the Rogers beancounters felt that an all-new product was a more sensible proposition, which is why the E-20a and E-40a all-valve integrated amps have nothing whatsoever to do with the preceding models. Indeed, they have little to do with Rogers.

Micros Can Be Mega

Martin Colloms | Apr 12, 2024 | First Published: Jul 01, 1993

Miniature components claiming high-end performance... Martin Colloms hears French company Micromega's Microdrive, Variodac and Microamp

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.

A Fine Line: The BB100

Ken Kessler | May 25, 2021 | First Published: Feb 01, 1990

Ken Kessler on Bill Beard's new line-level-only integrated valve amplifier

Manufacturers should not be criticised for responding to changing tastes. CD has forever changed the face of hi-fi, so all you're doing when you mourn the passage of the phono stage is increase the value of shares in sackcloth and ashes. Instead, be thankful that the companies in the high-end are intent on making the best line-stage amplifiers they can design. What you use for a phono section can be either your existing, pre-CD preamp or an outboard phono section. With this in mind. Bill Beard has launched an all-valve, line-level-only integrated amplifier, the first product to bear his new company's name.

Class Distinction

Ken Kessler | Sep 18, 2020 | First Published: May 01, 1985

Ken 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.

Affordable Audiophile Amp

Martin Colloms | Jun 28, 2022 | First Published: Jan 01, 1984

Can Audiolab's 8000A redefine the market? Martin Colloms finds out...

The new Audiolab range is introduced by the 8000A integrated amp, which sells for around £250. Trade rumours are that the first batch was sold out even before any press mention of the product, and that the few dealers appointed so far are finding it impossible to hold any stock. In these commercially depressed times it is certainly refreshing to cover a success story such as this, though I suspect that this model may be in short supply for some time to come.
