Are the better $$$ 845 tubes worth it sonically??
I have the ASL 1009 monoblocks (a pair of 845's per amp), and have the stock Chinese 845 tubes. Has anyone compared their 845-based amps with ANY other type of 845 tubes?
I am most interested in hearing about the KR 845's, as they are current production, and available from Czech at $430/matched pair . The older GE-type NOS 845's seem way to expensive.
I guess the main question though is WHAT differences sonically did you notice upon using a 'better' 845 tube, and was it worth it??
