John Coltrane, Crescent. Using this album as a yardstick to see how the new speakers are doing. I know this album from LP, tape and cd days, very well, and I LOVE to listen to it.

What playing this cd showed me yesterday was that it was time for a new set of output tubes. Got better than eight months out of them, during which I more often than not ran the amp for days on end between turnoffs.
Today with a new set installed it sounds great. The HR-1s are really dishing out the great sound. I do have a buzz and rattle coming from one of the speakers however for the lowest notes of Garrison's bass playing. I ran into it as well on another cd. I thought perhaps it was a tube distortion but no. Keeping an ear on it.
The version of this album in my collection is a Japanese K2 reissue. I probably listen to this one the most often of all my cd versions.
