With my Triangle Titus XS speakers that I've had for a good 15 years or so, which are smaller but similar to Cometes, were I to strt over again with them, I would look towards a tube amp. Lead contending tube amp vendors for me would be Jolida, Glow, Decware, and Rogue. If I could afford more, perhaps ARC or VAC or Atmasphere.
BTW the Triangle Titus speakers are one of the best sounding speakers I know of at low volumes with most any decent quality amp, even SS. They are the ones that convinced me that box speakers could replace my older Maggies, also low to moderate volume sound champs when set up well, years ago for low to moderate level listening.
