Jolida 1501RC hybrid integrated vs. Rogue's Sphinx

Don't know how much it matters in this case but teh Jolida is older and teh Rogue newer. That might matter even more than with most technology still in the case of the Class D amps used in teh Rogue. The Rogue uses Hypex Class D amp technology, not sure what model, generation or how old the ones used specifically are, but I have a lot of faith in anything that says Rogue on it more so than Jolida in general.

Cronus Magnum is a very fine tube integrated and sounds fantastic with the right speakers to match.

HAve not heard the Sphinx hybrid yet. Need to get down to my local Rogue dealer and see if he has it. I would expect similar good results but not best performance with the same speakers as CM. CM works best with higher efficiency, higher impedance "easier to drive" speakers and also well with planars, like Magnepan. Sphinx I would expect good results with all speaker types, including smaller modern designs that are less efficient, harder to drive, and attempt to squeeze more low end bass response out of a smaller box and drivers. With planars like MAggies, either might come out on top, not quite as sure, but I would give the edge to CM.

Class D amps are highly damped usually, a trait that will generally make them sound quite different than many though not all, tube amps.

Which sounds better case by case will be highly variable on many factors including personal preference.

Recording quality is always a big factor.

FWIW, I have my system using Class D amps tuned so that most lesser recordings still sound decent and more than just listenable, and the best recordings shine well beyond that. It does take some tweaking though usually to get to any target desired sound, so a straight out a/b comparison on a dealer system may not tell the whole story. Tube amps in general may be easier on the ears, but if its the amp that is enabling that with lesser recordings, the effects on others may not be as desirable. It all depends, YMMV, all the typical caveats apply.

FWIW, my local dealers system that uses high quality Rogue and ARC tube amplification (also high quality Rowland Class D amps) is one of the references I have used to get my system sounding the way I want using a CLass D amp best suited to get the most out of my particular speakers. So I palce way more value in getting the right combination of components in place and tweaking that from there as needed than I do in banking solely on tube versus SS amplification. I've found the best of each tend to sound more similar than not. THen there are all different flavors, many quite tasty, possible from there, in some cases flavors unique to the specific technology used.
