The Planet I used to own sounded good in my system with both a late version of the AQ Diamond X3 and Harmonic Tech Truthlink interconnects. It has been awhile, but I seem to recall that the later version of the Diamond's mids were smooth and had a nice warmth, whereas, the HT was more extended on top and presented a larger soundstage. Also, I had the stock power cord removed and an IEC jack installed, which allowed for a very nice improvement using various powercords.
