Have you even considered or looked at the new Sundown SIA line of amps. I just bought a SIA3500. They are supposed to have the SALT Korean boards and accept up to 9v of input IIRC. 3500 watts @ 1 ohm and 3,000 watts @ 2 ohms.Yes, their full bridge stuff wasn’t reliable. No idea on Colin. Just know he had a few issues in high school timeframe.
I have a china amp that it does 2800 rms at 1ohm.it sounds really good.i think its a suoer cl5.it has nice board in it.i bought it and used it for 3 days and i bought a shark 4500.i bought it just to see if it was any count and it puts out really good power.I’m in the market for a 2k+ Half bridge amp. I know full bridge is the new thing but I love me a half bridge and honestly may wire low in the near future. Eyeing a Sundown SAE 2000 (China I know) but am also looking at an Ampere AA 2000 and an IA 15.1 (wish I could find used). SSA IC2200 also but it is scarce and since covid prices have jumped super high. Anything?
