It seems a long time since we last reviewed a Cyrus integrated amplifier, but unpacking the brand-new Classic Amp feels like an entirely familiar experience. That distinctive Cyrus half-width casing looks unchanged from previous models as do the display and control buttons. But, while that’s not necessarily a bad thing given how the company’s products have always stood apart from the competition, it does feel like a bit of a missed opportunity to move things forward.

Build & features

You won’t find many differences in the specification sheet either, with the 70 watts per channel into 8 ohms claimed power output echoing that of previous generations of Cyrus integrateds. So, what has really changed? It turns out that the answer is quite a lot, but it is all on the inside. The company’s engineers have used the lessons learnt when developing the more premium XR series and implemented them here. The Classic Amp’s circuit design has been completely reworked with the majority of components claimed to have been upgraded for a better sonic performance.

Take a look inside the casework and you will find a generous power supply arrangement with a 304VA mains transformer and a high-capacity power supply reserve. The preamp and power amplifier circuits have dedicated transformer windings to prevent unwanted interactions, and the engineers have even gone as far as giving the digital control electronics a separate power supply to minimise interference.

Type Integrated 

Power 70W per channel

Phono stage? Yes (MM) 

Inputs Line level x4, optical x2, coax x2

Outputs Line level, pre-out

Bluetooth? No 

Headphone output? Yes (3.5mm)

Dimensions (hwd) 7.5 x 21.5 x 36.5cm

Weight 6.7kg

Take a look at the Classic Amp’s back panel and you will find that it is packed with connections. In that small space, you will find four analogue line-level inputs, a moving magnet phono stage and four digital inputs split evenly between optical and coax. The lack of a USB is a bit of a surprise but not a deal breaker in our book. The digital module tops out at 192kHz and doesn’t have DSD capability, which might be an issue for some of the more die-hard high-resolution file fans, but we think it won’t be a problem for most users.

While a headphone output is handy, it is a shame to find the 3.5mm socket stuck on the back panel where it will prove awkward to get to, particularly when the phono stage and Digital 1 optical inputs are in use. Surely Cyrus could have found a way to put it on the front where it belongs?

On a more positive note, we’re pleased to find that it is still possible to upgrade the amplifier’s performance through the use of a PSX-R2 power supply. Priced at £995/$1599 this outboard supply isn’t cheap, but does make significant improvements to the sonic authority, scale and control of the amplifier. 

Sound

We plug the Classic Amp into our usual reference system of Naim ND555/555 PS DR music streamer, Technics SL-1000R/Vertere Sabre MM record player and ATC SCM50 speakers, but also have products such as the Cyrus CDi CD player and KEF LS50 Meta speakers on hand to see how it performs with more price compatible partners. We also have Arcam’s new A15 integrated amplifier and Naim’s pricier Nait XS 3 on hand for benchmarking purposes. 

The Classic Amp is a surprising performer, delivering a more spacious and open sound than its compact dimensions suggest. It sounds more substantial and controlled than we remember older generations being, though it still doesn’t quite have the dynamic muscularity or authority of rivals such as the Rega Elex Mk4 or Naim Nait XS 3. But there is much else to like here. 

We listen to Donna Summer’s State Of Independence and are impressed by the clarity and crisp detail. This is an amplifier that can dig deep into the production and reveal plenty in the way of instrumental textures. Summer’s trademark vocals come through with nuance and passion while the dense backing instrumentation is rendered with a good sense of organisation. This is a tidy presentation; one that takes care to dot all the ‘i’s and packages the sound in a neat and easily understood way.

There is no shortage of agility here, with the Amp tracking transients and fast-moving dynamic shifts well. This quality extends to the lowest frequencies with the Cyrus delivering the song’s distinctive undulating bassline with skill and plenty of punch. Some price rivals sound even more assertive in the region, but this little amplifier still does well. Take care to match it with a refined and full-bodied speaker and you won’t go far wrong.

Rhythmic drive? It is pretty decent, but the Classic Amp doesn’t convey the momentum of the music with quite the energy or enthusiasm of the class leaders. It is still an entertaining and informative listen but both the aforementioned Naim and Rega manage to deliver the music with more verve.

Switching to Bizet’s Carmen Suite highlights the Cyrus’s composure and precision well. It isn’t the most enthusiastic of performers but still communicates the energy of the music well. The music’s savage crescendos are delivered with a surprising degree of punch, and as before we’re impressed with the amplifier’s controlled nature.

It images well too, with a soundstage that is open, spacious and nicely layered. The addition of a PSX-R2 takes this another step forward, adding a fair bit in terms of image scale and depth. Regardless of whether that optional power supply is connected or not, the amplifier’s stereo imaging remains pleasingly crisp, focused and stable even when the music becomes demanding.

Cyrus’s engineers have done a good job with the digital inputs where the amplifier retains its clarity and control. Detail levels are good and dynamics are expressive. There is a pleasing consistency in character between the analogue and digital connections that isn’t always a given. The story is similarly positive with the moving magnet phono stage and headphone output. The phono stage is insightful and decently quiet while the headphone output is as expressive as the speaker output. Some companies treat these features as something of a tick-box exercise but it is obvious that Cyrus has been diligent with these modules.

Verdict

The Cyrus Classic Amp is up against some tough competition but has a blend of sonic abilities that give it plenty of appeal. Add its compact size and upgrade potential into the mix and you have an attractive proposition for the money.

    Cyrus reviews always make be chuckle. This amp is nearly £2k and is way overpriced, considering the sound quality. A £2k amp should give you sonic ecstasy. The 40 year old, narrow and deep case design makes it tricky to fit into cabinets and still forces Cyrus to use small displays that look like something from a 1990s calculator.

    Cyrus’s engineers have done a good job with the digital inputs...
    Really? Where is the HDMI eARC? Its what average consumers want FFS. Drop down to 4 star in terms of features, in my view.

    Many companies are unable to read the market these days and it's a case of 'I did it my way' I wouldn't consider Cyrus now. Too expensive, confusing product ranges and those wee little 1990s calculator displays. People will yawn, but look at the HIFI Rose RS520 and then look at the latest offerings from Cyrus. RS520 every time. One box solution, massive display and 250WPC. It's also tiny and easy to install. Cyrus need to take a look outside of their comfort zone and see what HIFI Rose, Eversolo and NAD are doing with their latest devices. Cyrus are stuck in a rut, yet still have enough custom to keep them going. They will get outpaced soon, when other companies provide the sound quality and features people really want.

    The look reminds me of a 90's aftermarket car stereo that was trying to look futuristic.

    i have a calculator with similar display from the 80s that still works fine, if this amp is still working in 40 years time then it might be a bargain ...keeping things simple is a good thing...

    Sounds like your a Cyrus fan. I think Cyrus stuff is just as complicated as the HIFI Rose RS520 and as for lifespan, you'll need to wait to see if the RS520 lasts as long as the Cyrus amp and I reckon it will.

    The RS520 is better than the Cyrus in every department and you would need to spend a great deal more on Cyrus kit, to get all the features of the RS520 and you'd still be stuck with an inferior display on each device.

    I wouldn't take too much notice of their description of it's sound.
    In the AV Forums review 'pro's' column they said of this amp: 'Sounds absolutely brilliant'.
    But I wouldn't take too much notice of that either.

    I'd have to hear it myself before judging.
    There's no doubt it's overpriced though - not least due to being 'made' in the UK.

    Cyrus can have a sale now and then and discount their amps by £1000 and still make a profit. I think most of their stuff is £1000 overpriced. Made in the UK is no excuse in my opinion. They must have an efficient process, after all these years and don't seem to spend much of their R&D budget, with the same casework churned out every year, along with the small displays, which are almost useless at more than a few feet away. I like Cyrus, but they are too expensive. As I mentioned elsewhere, they might have to change their tactics and go with a better design at some point, when competing with so many great products in the streaming amp sector. HIFI Rose. Leema, NAD and Eversolo make some cracking products and Cyrus designs seem to be stuck in the past. When these great products are mentioned, you can see the entrenched Cyrus supporters get on the defensive and almost dismiss any other brand, with little regard for the product's feature set or build quality. The HIFI Rose RS520 is amazing and such a huge margin ahead of Cyrus. Cyrus have been sat on their laurels for years, expecting their products to retain the same revenue as they always have. I think the arrival of streaming devices and Class D amps will put the cat amongst the pigeons and Cyrus, amongst other well established companies, will be forced to change their strategy. So many lazy companies out there and we do need a game changer now and then, to shake up the market. I think the RS520 is such a product.
