Not in the near term, no. My KGSSHV should be arriving this week, so that will be my amp until Dr. Gilmore comes up with a better solid-state design. With the amp out of the way, the next step is the source. I want to compare redbook on a CD player available on Audiogon in the $5-7K range (Esoteric, Meridian, Accuphase, etc.) vs. a music server and USB DAC for similar money and see which I like better.
When that's done, and I'm finished with cables, power conditioning and everything else, then I may consider the SR-009. I really like the overall balance of my SR-007Mk1, and I get fatigued easily by bright headphones, which is the main reason why I'm just not in a hurry to upgrade. Even more transparency and the other 009 improvements would be welcome, but I'm wary of the increased presence in the upper frequencies.
