Hi! I want to know if anybody tried these combinations and how much different are in sound quality:

1-Digidesign 192 i/o with Apogee Big Ben world Clock

2-Apogee Rosetta 800 with BIg world Clock

3-Apogee DA and AD 16X ( in apogge say is not necessay the Big Ben to enhance the sound)

I heard the big ben really will enhance the sound of the 192 i/o 0 96 i/o
Also to the rosetta 800

the top is the AD -DA 16 X.
But you are talking about $6800 including the protool cards(16 ins and out)
when wih the rosseta 800 plus the big ben is about $ 4300 (8 ins and out)
and the 192 i/o plus the big ben around $4600 (16 ins and out)


The botton line is if the 192 i/o ith the big ben can be a great rival aginst the Apogge AD and DA 16 X

Thanks!
