Copland CSA100
Integrated amplifier £3988
Copland is one of the unsung talents of the high-end industry. Despite being in business for almost 40 years, the company has rarely grabbed the limelight. But that has more to do with the way the brand operates than the quality of its products.
This small Danish company makes only a limited range of electronics (often valve-based) and goes about its business in an understated manner. Products’ life cycles tend to be long, so new introductions are rare and done with little fanfare. So, when a new product does appear we’re keen to have a listen. In the case of the CSA 100, we’re glad we did.
As far as features go, this integrated could be all the amplifier most music fans will ever need. Despite retaining the company’s trademark clutter-free appearance, this elegant design packs in a digital module, headphone output and a phono stage into its well constructed chassis.
At its core is a hybrid electronic design, which uses a single 6922 double-triode valve in the line stage feeding a high-power MOSFET power-amplifier section. The result is a solid 100W per channel into an 8 ohm load that rises to a healthy 180W as impedance halves.
Those figures suggest that the CSA 100 will be able to drive most speakers to serious levels in all but the largest of rooms. We try both our usual ATC SCM50S and the more price-compatible KEF LS50 Metas without issues.
There’s an impressive degree of connectivity here. For vinyl fans, there’s a phono stage suitable for moving-magnet or high-output moving-coil cartridges, along with a balanced XLR and three single-ended line-level inputs.
As for digital, there’s the usual trio of USB, coaxial and two opticals. These digital inputs feed an ESS Sabre ES9018 Reference DAC used in a quad mono configuration to improve resolution. The use of this chip means the CSA 100 is compatible with up to 32-bit/384khz PCM files and DSD128. That should be enough to play just about any file potential users are likely to have.
It’s a shame the amplifier doesn’t have a proper display that shows the resolution of the incoming digital signal. All we have is a small LED indicating whether it’s DSD or not.
A USEFUL EXTRA
Unusually for an amplifier of this type, Bluetooth (in aptx HD form) is on the menu. It’s a £198 optional extra, not fitted to our review sample, and is a box we would tick. It would bring the convenience of phones, tablets and computers into the equation, and that can only be a good thing.
There’s a preamplifier output for those who feel the need to add additional muscle, an unattenuated line-out for recording purposes and a 6.3mm headphone socket.
If you want to hear how good this Copland can really sound you’ll need talented sources. We use our reference
Naim ND555/555PS DR music streamer and Technics Sl-1000r/goldring 2400 record player, but also draft in an Apple Macbook Pro loaded with Audirvana music software and plenty of hi-res music. Cyrus’s CDI integrated CD player also sees some use. Of course, you don’t need to go to the extremes of the Naim or Technics to appreciate the Copland, but it pays to give it a suitably capable signal feed.
If Copland’s use of a valve leads you to expect a stereotypical warm and comfortable presentation you’ll be disappointed. The CSA 100, just like every other Copland product we’ve heard, doesn’t do that. This is one of the most neutral-sounding amplifiers we’ve heard at this price. It makes class leaders such as Rega’s Aethos and Naim’s Supernait 3 sound a little uneven in comparison.

SPACE AND SCALE
We listen to the third movement of Mahler’s Symphony No.2 and the Copland sounds right at home. It has a spacious presentation and renders an expansive soundstage. It’s a nicely layered image with instruments sharply focused. The presentation remains stable too, even when the piece becomes demanding or volume levels rise.
We’re pleased with the CSA 100’s scale and authority, though both the Rega and Naim sound even more muscular when it comes to punching out crescendos. The Copland counters with sonic precision and a sense of fluidity that’s hugely appealing. It’s an impressively detailed performer too, picking up low-level instrumental strands with ease.
We switch to Björk’s Homogenic set and the differences between the Copland and its main rivals are clear. This amplifier is all about clarity. It excels in the subtleties and displays a level of finesse and sonic sophistication that puts us in mind of far pricier alternatives. It sounds impressively natural with Björk’s distinctive vocals, communicating all the idiosyncrasies that make her delivery such a treat.
The presentation is nice and open, even with an album as densely produced as this. It’s an organised and entertaining sound that captures the various moods of the album really well and displays the kind of transparency that allows you to forget the tech and simply sit back and enjoy the music. If you value rhythmic coherence and dynamic punch above all else, its rivals move ahead. It’s not as if the Copland can’t step onto the dance floor, more that it prefers to stand on the side and tap its toes.
Our view of the amplifier stays positive whether we use the digital or analogue inputs. The digital module is a good one overall, though the USB input loses doesn’t quite match the coaxial or optical when it comes to dynamic expression and overall clarity. We think the module is broadly on a par with the better standalone DACS at around the £500 mark.
The phono stage is good too. It retains much of the insight, agility and energy of the line inputs and doesn’t add too much in the way of noise. Equally, the headphone output is a good one, though its relatively high output impedance of 40 ohms means you’ll have to match with care.
Our long serving Beyerdynamic T1 Mk2 (600 ohms) work really well but the Grado RS1 (32ohms) and Focal Stellia (35 ohms) sound a little uneven.
In summary, the CSA 100 offers an excellent alternative to the established class-leaders and has an equally convincing (but different) blend of attributes. Impressive.
