something i have noticed about both sets of cables (i have owned both cardas & tara).
when you use 2 sets ( between source to pre and pre to amp) the sonic signiture of the cable is really magnified ( it makes sense, since the signal is amplified).
for example, the all cardas system was waaaaayyyy to laid back and the midbass was very exgrarated and a heavy loss of detail(it was like a cj pv5 was put in my system). also a noticeable increase in body and added ALOT of bloom.(golden cross)
with the all tara, there was a slight tendency toward brightness in the top octave and a little more forward and a faster cable ( less body & less bloom -(master generation).
what i finally came upon was xlo signiture II for the cd to pre ( this is a VERY, VERY revealing cable, also very coherant) and the cardas from pre to amp (smooth and adds body).
so imo dont be afraid to mix it up to find a sound that works well in your system.take home some interconnects from the local shop and find out what works. i was very surprised about the combination i found.
also the cardas cross is a less "carmel colored" than the golden cross.
For a well balanced cable with a little bit of warmth, you might want to check out the tara decade
hope that helps !!
