Pre/Power Amplifiers

Look at the latest iteration of Lindemann's network music player, the £3450 Musicbook Source II, and you'd be forgiven for thinking that nothing much has changed [HFN Jun '20]. This is still a compact unit, just 28cm wide and a mere 6.3cm tall, with nothing much on show save a power/standby button sunk into one end of the top-plate and an edge-mounted volume control, with a push-to-mute function, at the other.

Avoirdupois aside, Dan D'Agostino Master Audio Systems' Momentum M400MxV monoblock just may be the least fussy or fiddly power amp one can aspire to in the extreme high-end. Of course, something cute and tiny like a PS Audio Sprout [HFN Feb '15] or Quad Vena [HFN Jan '15] can be lifted with one hand and requires no degrees in electronics, but that's 'real world' gear. At £90,000 per pair, the M400MxVs are as exclusive as it gets, and such a strong physical presence is de rigueur.

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'.

Siegfried Amft, founder and MD of T+A, declares the intent of the brand's Series 200 is to 'combine the appearance of a Midi system with a high-end performance'. Midi, of course, is a word that evokes memories of 1980s/'90s hi-fi, so I'm surprised to see the term attached to a range that's rather more aspirational in its technology. You might think something has been lost in translation, T+A being a German manufacturer, until you lay eyes on the DAC 200 and its button-heavy compact chassis. From the appearance side, at least, the 'Midi' mission has been accomplished.

Sometimes manufacturers do listen! After Chord Electronics' DAC64 proved to be such an immediate hit, the company decided to figure out why everyone fell in love with it. Sure, it sounded wonderful. Yes, it had neat features like balanced and single-ended operation and its three-setting, user-adjustable RAM buffering. But that wasn't it.

By any standards, the Noble series from Berlin-based MBL is a looker. The components aren't massive – in place of slabby high-end units wearing their audio prowess on their sleeve, as it were, both the £11,500 N11 preamplifier and the N15 mono power amplifiers, at £13,900 apiece, are relatively slender units. They are also immaculately finished in a choice of gloss black or white, with accents for the control elements available in either polished gold or palinux (silver), with black detailing also offered if you go for the white main colour.

British company Crimson Elektrik started life in the mid 1970s as a manufacturer of ready-built power amplifier modules. Using these, a home constructor could assemble a fairly decent and up-to-date piece of kit, needing only to add a power supply, connections and a cabinet. Complete amps followed in 1979, initially in kit form and later fully assembled. The latter, which were similar to the 1200 series amps seen here, were reviewed in the June '80 issue of HFN.
