Same in my system, I made the interconnects very short, 50cm from source to pre-amp and 90cm from pre-amp to amp, it works fine to me.I also own a McCormack TLC-1 passive/buffered pre-amp but after many comparison I ended preferring my crafted one with only one IN/OUT line, no source selector in the between,thus the signal path is the shorther as possible.
If you wish it's visible in my Vritual System I published yesterday.
