i thought i'd love running direct from my wadia 860x to my vac 70/70. but after listening, i preferred using the pre-outs on my VTL integrated (basically the equivalent of a vtl 2.5 pre). the wadia direct seemed way too lean in my system. the vtl (maybe because of the NOS tubes i was using?) added body, dynamics, palpability. not what i expected at all.
it must be system dependent. maybe because my system is on the verge of lean anyway (martin logans, silver interconnects), i dunno. just what i heard.
