MBL 1611D

Can anyone tell me abt the performance for the MBL DAC top of the line his performance. N how much time need to run in. N how u compare the 24/96 with 24/192. Thanks!
I would rate it to be one of the best DACs out there; MBL is great equipment. The 24/196 is a bit more refined over the 24/96 as might be expected.
