Will a Rogue Audio Sphinx v3 perform decently with my Sonus Faber?

hello from london, my first thread!

i am using sonus faber olympica i standmounts (87db, 4ohm) in a smallish room (17x9 in feet), not crazy levels, jazz but also rock.

i have a complex setup (lab12 tube pre, arthur boxem class d power amp, and longdog audio hybrid phono stage for my Hana SL MC). and a REL T5.

I really need fewer boxes, but also some cash, and it is tempting to sell everything and buy a used decent integrated, currently eyeing a rogue sphinx v3 , not do well known here. But i can't audition 

i expect that it can't perform as well as what i have, but could i get reasonably close? maybe not for the phono stage. I guess i should go for the magnum upgrade, or the pharaoh, but that might be later...

yeah, very good point, and the hifi news review  is confusing- at least to me. "amp-friendly impedance - minimum modulus 4.2 ohm" but  equivalent peak dissipation resistance falls to 2.3 ohm- which they say is "comfortably about the 1.7 ohm often recorded by competing floor standers".

So i think that's OK? I can't find any measurement of peak current, 

chat GPT says

Based on the manufacturer specifications and independent measurements for the Rogue Audio Sphinx V3

, here are the details regarding its power and current capabilities:

  • Continuous Power Output: The amplifier delivers a minimum of 100 WPC into 8 ohms and 200 WPC into 4 ohms.
  • Measured Power: In testing, the V3 delivered approximately 96W into 8 ohms and 150W into 4 ohms.
  • Peak Current/Output: While a specific "peak current" numerical value (in amperes) is not explicitly listed in the technical specifications, the amplifier is designed with a high-storage linear power supply and custom 375 VA toroidal transformer, allowing it to drive difficult loads like Magnepans.
  • Load Stability: The Sphinx V3 uses Hypex Class D modules, which are known for maintaining high current into low-impedance loads, effectively doubling its wattage from 8 to 4 ohms. 

The Sphinx V3 is widely regarded for having strong, detailed, and authoritative bass, which implies high current delivery to the speaker

oops- that stereophile review is the Olympica NOVA- mine are the old ones!

You should do more than ok with the Rogue Sphinx.   Used it in a room roughly your size.  

It plays loud, with oomph.  Very musical sounding.  Doesn't sound like a Class D amp.  

The phono preamp is also fairly competent.

Preferred it to the Rega Brio.  

One odd thing can be with the choice of speaker cables.  It will not play (at all) with Kimber's PBJ speaker cables.  Experienced it, thought I was going mental,  and spoke with the owner about it.  He confirmed it.  One of those things that had to do with the cable connectors.  Not making this up.  

If you are up to it, you can call Rogue direct.  Very welcoming bunch.  The owner will discuss things at length.

going from incredible boXem to a middling tube amp doesn't make sense imo. get a solid stage integrated. the A-50 from Onkyo fits the bill and is a much more potent device as a whole with DIRAC DLBC
