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.
