Two thoughts:
- If you’re switching to an integrated in the near future just be patient and wait. Synergy is crucial when choosing interconnects, and whatever you buy now may not be as good of a fit with your new amp.
- Don’t bother buying new interconnects until you’re able to spend at least $100 as that’s where you’ll start to get significantly better performance (Dueland interconnects from member @grannyring might be a rare exception). Two of the high-value interconnects in that range that come to mind and would likely be a significant improvement over the Evergreens are Cullen Copper and Raven Audio Soniquil. Both offer trial periods so you can see/hear for yourself.
