Worth it to try a SUT with a 103R and Herron VTPH-2?

I'd be inclined to spend those resources on more music. But I am curious as to what the others think. 

So I assume your Herron already provides sufficient gain for the 103R.  Yet you're thinking about interposing a SUT between the two, presumably using the MM section of your Herron.  My bias is that this would be a step in the wrong direction, but neither I nor anyone else can predict what YOU will like best.  Also, your choice of SUT would have everything to do with the outcome.
