I have not heard the 508.20, but I do own the BAT VK-D5SE. The BAT has been an absolutely wonderful player over the years. I had rolled the tubes to find ones I liked best and I had Hot Rod Audio Mods put a new clock in it -- both solidified my liking of this excellent player. There's a reason BAT has stayed with this design for a long, long time -- its a GIANT killer.
