I left an Alpha running night and day for several years, with the cover on, and had no problems. The tubes might have deteriorated somewhat, but if they did I couldn't hear it.
CAL Alpha DAC - Cool Tubes?
This is a two part question. First, I recently purchased a CAL Alpha DAC with the 24/96 upgrade. I have found that I prefer the sound of a tube DAC and I am enjoying it very much. However, I've noticed that it is completely enclosed with no holes for ventilation and cooling. This is obviously by design, but I wonder if this is good for the tubes and internal components in general. I know that there are quite a few current and former owners out there and would welcome your comments. Second, I would appreciate any recommendations on tubes, tweaks, and such. I am currently running Mullards.
Thanks!
John
