@Sushi Box FX is correct, but more tubes is always better, to a point.So, the only difference is the DI out on the Finally? Someone who has an amp with DI out would have the same result with just the UA?
FWIW a UA into even a passive DI sounds fabulous, I often pair my SBFX preamps with a JDI, Type 85 or RNDI simply because I have them.
Another of my fetishes is for DI boxes, I have a dozen or so from 45+ years of needs and GAS, FWIW my current fave is the Finally V1.0 so the new 2.0 version is tempting for the added options and differences.
