system upgrade suggestions

thanks for the worthwhile suggestions and feedback. tried plugging the power cord directly
into outlet as Fpeel suggested but couldnt detect a
difference but will definitely look into purchasing another
power cord as it might save me in the long
run
Happy Listening

the speaker cables are symo ls 5sx. the pre-amp to amp
is musiclink by Transparent, from cd to pre-amp tara
rsc reference. the source is a psaudio ultralink I. Um..it sort of sounds electronic and lean even in the mids, the
highs are also emphasized, not even that subtle musically
speaking. It doest have a naturalness
as compared to the headphone system I use (sennheiser hd
600s and a melos sha 1 with an old phillips cd player.
I found a subwoofer didnt integrate well... too much bass
for the mids...it was a rel stratus 3. powercord to the amp
is from mccormack. everything is plugged into a power wedge 116.
thanks all.
Phil
