Yes I would. 75$/day can save you many thousand dollars
IMO, their is no better way to test a DAC and the sinergy with your system than trying it in YOUR system. Personally, I don't need 5 days to know if a DAC worth its cupgrade
15 minutes is enough for me to know if it is an upgrade , downgrade or a side move, I would be happy to find a local dealer offering it by example for MSB DAC in my room.
