HiFi Rose RA280

REVIEW

On occasion, audio companies can positively delight in subverting expectations, and the device you see here is a magnificent example of the practice. Suppose you were to consider the range of HiFi Rose streamers, most recently the RS130 streaming transport that featured in issue 230. In that case, you might assume that any matching amplifier would feature extensive connectivity and be firmly into the ‘smart’ category of amp we’ve seen in increasing numbers over the last decade.

One look at the RA280 should have you questioning such assumptions, and a more involved glance at the back panel will be enough to let you know you would be very far off the mark. Regarding operation and connectivity, the RA280 is undoubtedly a very ‘trad’ piece of kit—almost the complete opposite of the streamers. However, HiFi Rose has channelled their willingness to do things a little differently into the actual amplifier section itself.

No shortage of power

Like the larger (and more visually spectacular) RA180, the RA280 is a class D design. There are only two channels here as opposed to the four in larger amps, but there’s no shortage of power, with 250 watts available in 8 ohms. The genuinely exciting part of this section is lurking in the output. HiFi Rose has sought to deal with the notional ‘dead time’ when the circuit switches between states. The RA280 incorporates ultra-high-speed gallium nitride FETs intended to reduce this notional dead time to an irreducible minimum. I will note at this point that, by an astonishing coincidence, the most vocal proponents of the dead time concept happen to make other types of amplifiers, but it shows some interesting thinking on the part of HiFi Rose.

Neither is this the only interesting material choice in play. A switching power supply is used, and this can swing 2.5kW for dynamic peaks as required. It uses silicone carbide FETs to further beef up the means of delivery. Something potentially handy is that this is a switching PSU with universal voltage. Even if the means by which the RA280 works are notionally conventional, the details by which it does it are not.

This amplifier section connects a preamp stage that uses a conventional volume pot with an actual start and finish point. This has a very pleasant weight and feel, but it’s only fair to point out that, with the balanced input especially, the minimum position on the volume control is not actually silent, and the mute function will be needed to ensure that the amp actually stops making noise. It’s unclear if this is deliberate, but this is my first time seeing it.

Exclusively analogue

The RA280 is exclusively analogue in operation: a single XLR input and a moving magnet phono stage support three RCA line inputs. There are no digital inputs, streaming, or headphone sockets, for that matter. This might seem odd given the connectivity of the streamers, but when you consider them as a pair, it makes rather more sense, with each box handing its own selection of inputs. There is only a single subwoofer out, though, which means that any thoughts of routing an external headphone amp will need a modicum of thought.

However, many people will be willing to work with that issue because the RA280 manages to be utterly charming in the metal. Nothing I’ve ever tested from HiFi Rose has been anything other than solid, but the exquisitely made RA280 belies the asking price. The casework is extremely solidly built and immaculately finished (and your irregular reminder that these are not the same thing) in the black and silver options. The reduction in ‘visual drama’ over the larger RS180 works to the advantage of the smaller amp as it retains plenty of fascinating features, the lovely input selector and VU meters being particular highlights, but without looking like a committee of people that never actually met designed the thing. A small but perfectly useable remote control completes the functionality department.

The RA280 doesn’t let up on the surprises when you start listening to it. Having never previously sat there listening to Class D devices, acutely aware of much in the way of a notional dead zone in the performance at any point during listening, it might not be too surprising a statement that I haven’t heard anything on the RA280 where I can definitively say ‘yes, that’s the gallium FETs.’ If this sounds underwhelming, it really, really shouldn’t.

It doesn’t sound underwhelming because the RA280 performs like it contains a highly potent quartet of KT88 or KT120 valves instead of the class D modules and their attendant output devices. How it gets stuck into Over Tage by Svaneborg Kardyb [Gondwana] is positively luscious regarding its richness and tonality. It distinguishes between avoiding sounding overblown or soft and matches refinement with an extraordinarily vivid presentation.

Headroom heading

Where the RA280 is entirely unlike any valve amp I’ve ever tested is that headroom is heading happily in the direction of unlimited. The bulk of listening was undertaken in company with the excellent Focal Aria X No3 and nothing in the Focal’s requirements so much as scratched the surface of the headroom on offer from the HiFi Rose. The power on offer is never overt; it’s perfectly possible to select a low-level, late-night friendly volume setting without recourse to a pair of tweezers. At the same time, there is a level of drive and current delivery that ensures that the Focal is driven rather than powered. The more current-hungry Kudos Titan 505 stood in for the Focals for a time, and the RA280 was utterly unphased by its requirements.

Where this makes itself felt is a fabulous level of bass extension that possesses a detail and control that ensures that even the huge and complex electronic underpinnings of Martina Topley-Bird’s Game [Self-released] are articulate and engaging while still entirely seismic in its weight and depth. Anyone coming from a more flat earth style presentation might find that the RA280 isn’t as consistently ballistic as amps from that school of design, but it would be a considerable stretch to describe it as languid.

The phono stage is a genuine surprise as well. Having not previously encountered one from HiFi Rose before this point, I wasn’t sure what to expect or if it would be anything other than a by-the-numbers’ we have included this feature type affair. It perfectly complements the lush overall balance of the amplifier. A fine example is Signals by Marconi Union [Just Music]. It plays with weight and authority, nailing the brooding scale and menace of Strata. HiFi Rose has done a fine job covering the basics; noise levels are negligible, ensuring detail is easy to perceive, and they’ve also done a commendable job of ensuring that the gain syncs closely to the other inputs. With these basics in place, the phono stage feels like an organic extension of the amplifier circuit. Calexico’s Algiers [City Slang] manages to be rhythmic and engaging but never at the expense of a fabulous richness to both voices and instruments that encourage you to keep listening, not because the result is technically accomplished but because it sounds genuinely good.

Unshowy

This unshowy but supremely accomplished ability to keep you listening to the RA280 is a party piece that surprised me long after I installed it. A considerable amount of testing took place with an Astell & Kern SE300 portable player running as a Roon Endpoint into the balanced input of the HiFi Rose. The ladder DAC in the SE300 demonstrated the same effortless ability to resolve without nitpicking that the RA280 does. I often found myself using the combination in preference to my resident system because it was so easy to listen to in the wholly positive use of the term.

The HiFi Rose RA280 might subvert your expectations of how it performs based on the sophisticated nature of the streamers, but dig a bit deeper, and the company’s ethos is still readily apparent. Like the streamers, this is an amplifier built the way that the company feels it should be done, and the result is deeply impressive.
