I recently got myself a CL1000 to run with my Zanden 6000 amplifier and Fleetwood speakers. All I can say is that it is a serious upgrade in terms of musicality from the C900U I had before. The C900 is awesome, but the CL1000 is like moving from digital to analog. There is just something more “real” about the sound. Additionally, it is amazingly quiet - absolutely zero tube noise whatsoever. Last night I was listening to Steely Dan Aja and was just amazed at the depth of the soundstage - the music sounded like it was coming from 10’ behind the speakers.
My big question is - has anybody tried rolling the stock tubes in the CL1000? I usually like 60s Amperex the best and am trying to figure out what to put in. I know Luxman probably tests and only uses the best of the EC88CCs that they get on these, but my experience with upgrading tubes on their EQ-500 is that it made a much bigger difference than swapping cables. I’m certain a set of better tubes will only improve the CL1000.
Any ideas appreciated, and I will check back in when I have experience with a set of new old tubes.
