I've tested this 5V LPS with my REGEN, but somehow I liked the sound with the original Meanwell SMPS more. I can't explain this. In theory should the "high end LPS" be better.
And more important everyone keeps the REGEN instead of the JB. In some cases the JB can help the REGEN but I see no one get rid of the REGEN and switch to the JB only. The JB is no competition for the REGEN. It can be complementary at best.
