I have used Vipers between my PV-10A and Premier 11A and was very impressed with the results. I have since upgraded to a Premier 16ls/II and MF2500A with Anaconda interconnects; I am very impressed with this combination. I have listened to a few different manufacturers interconnects in my system and have always come back to Audioquest. I would recommend them highly. The Pythons will be a discernable step upward from the Corals. If you are patient you may be able to hit your budget for the Pythons (used or demo) or at least come close. You may want to do as JD suggests and find a dealer who will let you audition or buy used.
