I recently purchased your DAC 0.1, and I must say it sounds incredible! Especially considering the relatively affordable price. I notice that it sounds much better after several hours of warm-up. My question is this: how long can one leave the DAC turned on? Is it safe to leave on 24 hours, or should it be turned off at night? I do not want to ruin the life of the tubes.
I tried to contact you on abbasaudio.com, but there was an error with the submission form. Apologies for this odd method of contact.
Thanks,
-Joe
