The VAC Signature is a wonderful piece and no concerns about the manufacturer.
I forgot to add, I have owned the Dodd and its a wonderful preamp - right up there with the VAC that I currently own. I owned mine a few years ago and had issues with the battery charging making the unit somewhat unreliable. It looks like the Dodd uses a new system now, but I would suggest researching that issue closely.
In fairness to the OP, let's drop the TRL debate.
