My two Pfennig's worth:
I am running a Crown XLS 1502 on DIY MTM speakers (dome tweeter, 92dB sensitivity). If I really turn it up, I do get a little bit of hiss. At best, these amps are mid-fi, sound okay but do not measure anywhere near the top of the heap objectively (mediocre SINAD, limited bit depth resolution, etc.). I know some of the overtly subjective "audiophiles" on youtube go nuts as this being the best hifi amp available, but I bet none have ever touched a measurement probe to find out for real).
When I get to my 3pi/6pi build, I will be using Hypex NCORE series (likely NC252MP series). Top of the heap in objective measurements, and by all accounts dead quiet (in Europe audiophonics.fr has very reasonable pricing of 391 euros on this stereo amp. But if you want you can spend up to $2000 USD for the boutique name versions of the same thing  ).
XLS 1502 objective test:

Good luck!
