These are rare as hens teeth but might be worth a gamble. I doubt Classe would give you the time of day if you ever had to ask for support.

Class D Option For Bass
I just purchased a little crossover from Sublime Acoustics and will be playing with bi-amping in the near future. I will use my tube amp for mids and highs but thinking class d for bass duties. I think I’d like something a bit nicer looking than Crown. I know they are a common go to for lots of cheap class d power. I’m not sure how much some of the newer designs like Purifi and GaN FET will make when playing no higher than 250hz max. My short list right now is VTV, Wyred 4 Sound, and ?. I know, pretty short list. I’m sure there are a ton more options but I haven’t really kept up with class d since falling for tube amps. Looking forward to everyone’s thoughts, thanks!
