Pre/Power Amplifiers

Back after a hiatus of nearly a decade, Trilogy’s founder Nic Poulson has returned to amp manufacture, having spent the interim producing mains filters and regenerators. Both the promise and the standards of Trilogy ‘Mk I’ have been maintained in the rebirth, but with new twists, including microprocessor control. Poulson has revived Trilogy with three models, continuing the 900-nomenclature of the 1990s units. The 909 preamplifier will most amuse the tweaker because it’s all-valve, using three ECC88/6922s and a 6U4P rectifier, but it boasts features usually found in cutting-edge solid-state products, or valve exotica from the likes of VTL, McIntosh and other American makers.

There cannot be many words more overworked than ‘classic’. Sometimes it means a previous model, kept in production ‘by popular demand’, perhaps because the new replacement model doesn’t quite cut it. Sometimes it means a new emulation of an old and once successful product, which may bear little real resemblance to a famous forebear. Conrad-johnson’s website straightforwardly lists all its discontinued models as ‘Classic Products’.

There is something about the Italian high-end that gets my juices flowing. It’s the style, the grace, the sheer passion that goes into the design – and the absolute certainty that there will flaws of epic, forehead slapping proportion. Exhibit A – the Audia Flight Pre remote control. Utterly gorgeous, CNC-machined from an aluminium billet and offering an innovative multifunction interface that keeps the button count to a luxurious minimum.

Ian Harris and Paul Miller hear the amps that crown MF's 20th anniversary

The kW and kWP are the final models in Musical Fidelity's 20th anniversary Tri-Vista series, and are intended to be the ultimate expression of the company's skills as amplifier builders. In contrast to the nominally 'real world' SACD player and integrated amp, the pre and power amps have been built on a totally cost-no-object basis – to borrow MF's own words, they're 'simply the very best we can do'.

Classic tubes meet modern tech in the £30,000 Project T-1 monoblocks. Is this Marantz's ultimate amplifier, asks an awestruck Ken Kessler

Contemplating the Project T-1 power amplifiers from Marantz, I realise that nothing in hi-fi should surprise us any more. If, in 1990, someone had told you that, by 1997, the hi-fi community would be clamouring for single-ended triodes and horn systems, that Quad and McIntosh and Marantz would reissue their valve classics, that Mobile Fidelity would open a new LP pressing plant and that Krell and Audio Research would introduce integrated amps, you'd have had that someone committed.

Martin Colloms hears the ultimate amplifier system from one of audio's elite names: the No26/No20.5 pre/power duo and No25 phono stage

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.
