Ive bought quite a few discus from Mr Huang back in the days. His discus supplier was always Discus Sanctuary from Malaysia. He use to supply many of the other LFS with discus and if you wanted pick of the shipment, you would have to be there the day of shipment to get the really nice fish. Back then Discus Sanctuary would post a list of what was coming in to Mr Huang on another forum and when the shipment was due to arrive. I always made sure to be there the day of shipment and was rewarded with some really nice fish. I even helped Mr Huang unpack and acclimate a huge shipment from DS at his home one time, and while i was there the owners from other stores would come in and get what they wanted. I have not been to his new store yet as I no longer keep discus, but I am disturbed to hear that he would intentionally drop the temps on the tanks. If that is what is going on, i would steer clear. Kenny and Hans are top notch and you cant go wrong with either. If you see something you want from Kenny when his new shipment comes in, make sure you call right away, he sells out very quickly. If you are looking for breeding stock then look no further than Hans, he sells some amazing adults and proven breeding pairs. His prices seem to be a bit high, but you get what you pay for, and Hans fish are AAAA+++++ quality.
