@rvpiano ime the power cord from the wall to the conditioner is actually the least important PC in any system -- provided you get a good base level top let the conditioner do its job then you will get more impact from the PCs to the components. This assumes a conditioner that is not current limiting
The Elite cord itself is to my mind problematic as per IsoTek's own description it is not suitable for high current usage -- a PC to a power conditioner should be for the highest current rating possible (unless you only use the conditioner with sources)
Elite can be used with small to medium power amplifiers to great effect but for very large power amplifiers EVO3 Optimum proves the better choice.
In terms of where best to try a PC upgrade I'd start with the turntable (in my experience turntables are very sensitive to PC quality -- a step up from v2 to v3 Marigo Iridium in my system brought appreciably improved tactility and stability to my EAR DiscMaster), and the CD Transport
The latest AQ PCs are good value for the performance and worth trying but price/performance also depends on the country you are in
