Help with which amp board to get

Hi all years ago i had a 41hz amp 6 basic loved it i thought it was better than my musical fidelity pre and power amp. Now i am looking for a ready built board with same sort of quality but with a bit more power for when i fancy a blast. Been looking at the hifime diy boards. Any advice help would be great
 
I am using a 500 watt switching power supply but I also used a regular 300 watts transformer.
With both it plays more than loud enough for my taste, It definitely has a lot more punch than the TA2020 chip in the Amp 6 (or the Charlize, which is my reference) The TA2022 chip in this one still has the trypath magic that is hard to find in the modern class D amps.
