Douglas Connection 9 awg speaker cables might do nicely. You should be able to get into a 15 foot pair for around $310. I have heard Douglas cables with tube amplification and it sounded great, in that they have great highs, but not edgy or bright sounding. Bass impact is really good.

I had Morrow SP2 speaker cables in my solid state home system for years, but I recently went with different cables and it was a huge difference.
