jroth has made some great suggestions on the speaker cable.
by sticking with a major player, you can sell them pretty easily down the road.
if you are looking for a netrual cable that is revealing - the xlo is a great choice. if you are looking for a warm cable then the satori.
most cable fall into two camps
1.revealing/detail/fast- xlo,coincident, nordost
2. warm,,bloom,slow - cardas,az satori
finding a "neutral"cable is difficult.
the fast cables sometimes can have a lean midrange and bright top end.
the slower cables can have a midbass bloat and/or obscure detail that the image specifity is gone ( cardas comes to mind)
i would check with dynaudio and other audiogoners on what manufacture they suggest with speaker cables with your speakers. they were voiced with a certain brand and solid state gear and go from there. ( i might suggest the xlo- they are a awesome cable). the dyna's image like crazy and are not bright speakers imo
since you only need one set of interconnects i would try to get my hands on as many as i could and experiment ( also a good idea for the speaker cables if you can)
for innterconnects some suggestions are:
coincident -neutral and good budget interconnect
xlo signiture 2- neutral / transparent
discovery plus 4- ever so lightly warm side of neutral- can be found very reasonably. great perfomance / dollar ratio.
straightwire -nice midrange cable and images very well
try the major players first. if you find something else you can resell them easily.
get your hands on as many as you can !!! by the time you are done, your ears will be very trained toward small changes like these.
then when you find a smaller /unknown company your ear will be trained. also, with smaller companies, make sure there is a 30 day return policy.
i would save power cords for last.
hope that helps,
