I'm thinking about profiling amps with the Kemper and my VB-101 and I'd like to know about the transparency of the Balanced Pre-Sim line output compared to DI boxes like BSS, Countryman or Palmer.
well, the Direct out is just an active DI at the loadbox output. Wide bandwidth, fast response, a very good DI I think, but do not expect any color from it it was designed to be transparent.
