I'not that concern about miniaturisation.
I Will prefer a much larger DAP that offer the "very ultimate" sound without the need for an additonal Amp.
--> HEY M. NAGRA... Please make un a DAP ! :-)
Today my Ultimate "transportable" setup is... 5 Kilos : RWAK 100 + RWA Bellina Pro HPA + Fostex TH900.... All this fitted in a carying case !
I know I am Crazy... But this is what out hobby is all about... Isn't it. :-). ?
