what a design, it sure is one of a kind

[@joscallinet6260]

@Duke Wilmer: I recently purchased the HiFi Rose RA180 - not only for its unusual appearance, but also for its cutting-edge version of Class-D amplifier technology. Yet another feature of this integrated amplifier which I wished to take advantage of is its two-level grouping of speaker outputs which you mentioned in your review. HOWEVER, in my case, I have assigned the second pair of speaker outputs to drive my HIFIMAN Susvara headphones which, unlike most other headphones, require a hefty amount of amplifier power to drive them effectively.
Since the RA180 does NOT feature a headphones jack, I cobbled together a pair of chassis-mountable female XLR sockets and wired them to the second row of speaker outputs, into which I then plugged a 4-pin-to-pair-of-male XLRs headphone adapter cable, into which I in turn plugged the balanced 4-pin-plug from my Susvara's headphone cable. The RA180 drives them capably, with more than enough reserve power.
I DO NOT recommend that anyone use this workaround to power far more sensitive headphones like Focal's Utopia 2022 - the amplifier will quickly overpower and destroy them. But for high-power-demanding headphones like the HIFIMAN Susvara, it's a pairing made in heaven. I'm driving my RA180 from the balanced outputs of my Italian-made Aqua HiFi FORMULA DAC - the sound quality is superb.
I am also looking for a good bi-ampable loudspeaker to connect the first set of speaker outputs to, so I can take full advantage of the bi-amplifying and crossover-setting features offered by the RA180. Any suggestions?

PerListen R7Ts or S7Ts are an awesome pairing with this amp if you want something that is as truthful as can be. If you like the Susvara (awesome idea with using it with the Ra180 btw) you'll really like these. I also like it with the Sonus faber Olympica Nova II and III as well as Totem Forest Signatures if you want a more forgiving sound for certain tracks.

The Rose or MA352 amps? What's the difference?
