Is there an updated equivalent to the DP88 out there / in the works? I like the front panel of the Quantum, the DP88 and Studio 1824c. The Studio 1824c is a lot cheaper than buying another Quantum if I don't need the thunderbolt because using ADAT. Are the Quantum and 1824c compatible for this purpose? If so are there any down grades in quality in the Studio 1824c in terms of converters and preamps from the Quantum?
