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!

Thanks everybody for the replys. It does seem strange to me to have tube equipment that is totally enclosed. I've thought about drilling some holes in the cover over the tubes, but would be a afraid of making the cover look like hell! I wonder if the eclosure is some kind of performance design?

Has anybody had any experience with tube dampers, isolation components, etc? I'm breaking in a LAT digital cable and associated equipment is a McIntosh MCD7008 changer, McIntosh MA6450 integrated amp and KEF 104/2 reference speakers.

Newbee- My upgraded 24/96 unit still has the standby switch.
