Integrated Amplifiers

With solid-state and tube/transistor hybrid models in its range, Copland returns to its roots with an all-analogue, all-valve integrated that supports aftermarket tube upgrades

By Copland's own reckoning, its noughties-era CTA405 integrated amplifier [HFN Aug '07] was an 'object of desire for audiophiles worldwide'. Now, some 16 years later, it has taken the idea of that model and considerably overhauled it – the £6500 CTA407 is both recognisably a descendant of the '405 and also markedly different.

This new heavyweight integrated blends inspiration from D'Agostino's Momentum HD preamp and MxV power amp into an app-controlled design with modular upgrade path

Integrated amplifiers are a matter of lifestyle choice, and we've all heard the arguments about why they are either better or worse than separate pre/power combinations. Whatever the sales pitch, pro or anti, the bottom line is that you are choosing space-saving over possible audiophile preferences. With the Momentum MxV Integrated – the other one in the family being the less-costly Progression [HFN Nov '20] – founder and chief engineer Dan D'Agostino is giving you absolutely everything in a single box, for a heady £73,998 in silver or black.

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.

Denon's Design Series brings us this attractive-looking two-box system, combining disc playback with streaming. But does style and flexibility mean a compromised sound?

Each of Sound United's two mainstream hi-fi brands – Denon and Marantz – has its own take on compact, room-friendly separates. In the case of Marantz, it's a lineup comprising an integrated amp and a USB DAC/headphone amp, each styled in 'retro' casework designed to evoke memories of Marantz amps of the past.

Denon has been in existence for 111 years, resolutely supporting CD playback for the last 40. Its latest CD disc spinner handles SACD too, and joins the 1700 series amplifier

The Denon duo in the limelight here are an obvious refresh of the previous generation DCD-1600NE disc player and PMA-1600NE amp, introduced in 2017, rather than entirely new designs. Partly that's because both the £1299 DCD-1700NE and £1699 PMA-1700NE look very similar, if not identical, to their predecessors. The solid construction, metal front fascia that curves to ensure the Denon logo catches the light, the weighty volume knob in the middle of the amp, the old-school tone controls… it's all very par for the course, as is the choice between black or silver colourways.

Once in a generation a company will emerge, often from left-field of audio’s mainstream, with a concept so original and innovative that it has the capacity to re-define the expectations of a product genre. That company is Devialet of France and its product is the D-Premier integrated amplifier, expected to cost around £12k when launched in the UK. Embarking on this review, little was known about the nitty-gritty of the D-Premier aside from its description as an ‘ADH’ (Analogue/Digital Hybrid) amplifier. It was not exhibited at CES in January nor formally announced to the press, so much of what we’ll discuss here is derived from very close inspection and even closer lab work, all exclusive to Hi-Fi News.
