Interconnects for Tube Preamp & SS Power Amp.

I'm looking for quality Interconnects for Rogue Audio Perseus
Tube Preamp and Parasound SS Power Amplifier. I've tried
Straight Wire cables, bass is great but not so highs.
Thanks in advance
The Harmonic Technology Magic Link 2 is great between my tube preamp and SS amp. Very smooth, detailed sound but all frequencies are revealed evenly. Maybe you can find a good deal here! I did.
