I left my DAC on 24/7 for the three years I owned it. They don't use a lot of power or get warm, so just leave it in a well ventilated spot. They don't require any special maintenance, calibration or alignment.
The Transporter is an excellent piece of equipment. You won't be disappointed if you buy it. I did not end up with the SB3/DAC combo because it "beat" the Transporter but because I thought the other was a better value. (Transporters were $2,000 at the time with no discounts around. Now they are not too hard to find for about $1,300.)
