I used a Rogue Sphinx hybrid integrated (tube preamp, Class D amp) for a while with Altec 890C Boleros and then Altec 604Es. It was fine but I went back to using a conventional SS Marantz integrated and sometimes a HH Scott tube integrated. Nothing wrong sonically with the Rogue but I preferred the features of the Marantz, especially its superiority with headphones.

I'm asking because I really want to use the Hypex Nilai 500 mono block kits with my 2 way diy build.

I have the Crown 1501 and 2502 XLS amps but wanted to try the better Class D amps.

  Why would you ever be looking at a 500 watt amp to drive horns?
  
  Granted Class D is a cheap way to get 500 watts but for horns perhaps look towards fewer watts of higher quality such as the ones I've suggested.
  
  In any event arrange to borrow a few short-listed amps before you commit, as the matches with speakers and room are more important than the basic spec can indicate.

    with my other lower efficient speakers along with the horns project.
    
    Years ago I ran Counterpoint SA-1000 with Phase Linear into my then Altec Model 14's, sound really nice and not noisy at all.
  - What the world needs is Ultra low-noise, Ultra-transparent 5 watt class D amp - Jon L 13:36:31 04/21/24 (0)
    For our horn speakers. I have multipole class-D and GaN amps, not to mention SS and many tube amps, but many high-power amps simply have too high a noise floor on 110db+ sensitive horns. I wish for Ultra low-noise, Ultra-transparent 5 watt class D amp powered from batteries at their native voltage without regulators...at a low price.
