A lot depends on your use case. Preamps only or mix of I/O such as EQ and Comps? Power is a big consideration as some modules can be hungry.
How you intend to integrate into your set up will affect what to get. I had been considering the Cranborne with the USB interface but was hoping for an updated as the design has been around a while, and I'd like something with lower latency. Been thinking the better option might be a chassis with Adat and built in conversion. Here what you use for converters unless you are all analog matters.
My strategy has been incremental upgrades as my needs grow. The Neve 88M along with an 8 channel preamp with Adat. Looking at the Heritage OST-8 once I am ready to descend into the rabbit hole. Nothing I saw out of NAMM this year gives me much hope for anything better anytime soon. Would have loved to see some options in Dante.
