Integrated Amplifiers

There’s a back story to the Virtus A3, Canor’s curious integrated dual-mono hybrid amplifier. I first encountered the design at the brand’s impressive factory in Prešov, eastern Slovakia, but this was in the summer of 2023, long before production versions rolled off the line. At the time the amplifier looked close to completion and was demonstrated playing into FinkTeam’s Borg loudspeakers. However, changes to the specifications along the way, including a decision to increase its power output to 2x100W/8ohm, ensured its development took rather longer than anticipated.

First seen in 2023 at Munich's High-End show, Chord Electronics' Ultima Integrated is steadily finding its way into selected hi-fi emporia. Based around John Franks' tried-and-tested amplifier architecture [see PM's boxout, p65], it's the entry point to the Ultima family, whose rollout began with the flagship Ultima monoblocks .

Three thoughts hit me as soon as I switched on the Copland CSA100 integrated amplifier. The first was that it was an all-embracing, do-everything tube/transistor hybrid like the Vinnie Rossi L2i-SE [HFN Jul '20], rated at a similar 100W/8ohm if at a fraction of the price, at £3498. The second was that I want it to kick off a fashion for cool, fully-loaded integrated hybrids because they are the smartest option for offering the best of the tube/solid-state worlds. The third is the realisation that I need to look deeper into hi-fi system building.

Nothing causes more consternation than a product seemingly 180 degrees at odds with a company's core philosophy, whether hi-fi, cars, watches, what-have-you. Audio Research dealt with the repercussions of its first solid-state amp… but an all-transistor amp from the equally tube-centric Copland? Not its first – these were the mid-'90s CSA8/CSA18 – so the CSA70 probably won't cause too much of a ruckus despite the absence of bottles.

Of late, I have been banging on, to the dismay of many, about how high-end audio has priced itself beyond any regard for reality. That said, context is everything. So, if I tell you a burger can cost £18 in a London restaurant and that Copland's CTA408 integrated tube amp is actually a bit of a bargain at £6398, please accept that I'm painfully aware the latter sum is a fortune to many, but the former is highway robbery. Eighteen quid for a burger!

After nearly four decades' worth of using Dan D'Agostino's designs, from Krells in the 1980s through to his more recent, eponymous models (I use a Momentum Stereo as my solid-state reference and love it to bits), I thought I knew what to expect. Silly me: surprise No 1 provided by the D'Agostino Progression Integrated was that I could lift it without any assistance. Surprise No 2 was a price under £20k.
