Product Description

Arcam A39 integrated amplifier draws on the 40 years of amp design experience at Arcam, using the best quality components and engineering practice to produce a unit which will give many years of musical pleasure and reliable service.

Class Leading Sound

A39 sets new standards and providing class leading sound quality for the best possible reproduction of your music. Great steps have been taken in improving audio sources and loudspeakers lately and the time is right to match them in the field of amplifier design. This model sits above the A19 and A29 at a far lower price than the A49, making it a sweet spot on Arcam's range.

Original Detail & Authority

With a class G amplifier, toroidal based power supply, acoustically damped chassis, paralleled transistor output stages and exceptionally low levels of distortion the A39 is capable of reproducing music with all of the original authority and detail. The A39 has been designed to transcend the competition in leaps and bounds, with a massive 125 watts per channel into 8 ohms and 240 into 4 ohms.

Pure Class A Mode

Delivering 20 watts in pure class A mode whilst allowing for huge extra power reserves from the latest in class G topology, it is both clever and efficient. Distortion is measured in less than one part per million so that this massive power is delivered with total control and finesse.

Press Reviews

  • 'Arcam's new integrated amplifier promises superior sound and affordability thanks to Class G operation.' (Hi-Fi Choice Magazine Feb 2015)

  • 'What I really appreciate is its even-handedness, its sheer unflappability and generally pleasing and musical demeanour.' (Hi-Fi Choice Magazine Feb 2015)

  • 'Rather than delivering out-and-out sonic performance, they have proffered an attractive blend of crisp, smooth, enjoyable sound and lots of facilities... Now though, the FMJ A39 doesn't need any extra provisos; it's right up there on the pace in sound quality terms, with no excuses necessary. But it continues to possess excellent build, facilities and styling too. In other words, it's one of the company's most competitive offers ever, and well worth auditioning.' (Hi-Fi Choice Magazine Feb 2015)

  • 'There's still plenty to be had from the Arcam A39, particularly if scale and authority come high up on your must-have list.' (What Hi-Fi Magazine Feb 2015)

    I heard this amp in comparison to a few others at the price: Roksan Kandy K3, Audiolab 8300, Naim Nait 5si, Primare i22.

    My ranking:
    i. Roksan
    ii. Naim
    iii. Arcam
    iv. Audiolab
    v. Primare

    You can guess which one I bought! :). Despite this I didn't find the Arcam lacking in any way and was even told I may get it a better price as the replacement may be out soon, however the Roksan was simply more convincing and fun without doing anything wrong. It simply got to the heart of the music. Have a look at the HiFi Choice review available via the Henley site.

    Jeff will have to be eating his hat now as I just spotted a meagre 4-star rating for this on What Hi-Fi. I however, managed to get a good deal on mine, and I'm happy enough with it to question that 4-star rating.

    Unfortunately, there weren't a huge number of comparably priced amps around to try out when I got the A39, so maybe I can't justify my 5 stars yet. The closest-priced competitor around in my mind would be the Rega Elicit-R, but I found the Rega range very hard to pair with speakers, always sounding a bit harsh, compared to the A39 giving a much more natural tone that goes great with my Spendors' balanced but powerful attack.

    I'd say best bits with this amp are: neutral presentation, dynamics, detail at low-med volume, capacity for high volume. It shares a lot in common with its siblings in the A*9 range.

    This amp totally blows the Roksan Caspian out of the water!! I had to listen to this amp and Audio Affair was the only place I could find (in the UK?) that has Arcam and Roksan in stock. I'd read good things about the Caspian, but this amp just offers so much more, better dynamics, better imaging and its all just effortless. This has to be the new benchmark at this level and if this doesnt win the What Hi-Fi category at the next awards, I'll eat my hat. It only loses a star as I wish it was cheaper, but you get what you pay for and this is worth coughing up for
