@kdude66- Totally agree the DI is a fantastic tool for an audiophile to learn what they like. I do agree with sprocket75 that putting some power behind the DI's does add some presence and "realism" and I listen at an average volume in the mid to upper 70db range with peaks in the mid 80's.
This big SS vs SET amps brings up an important personal distinction and there aren't too many speakers out there that can sound good with both big SS and SET. For many years I wondered what was wrong with me because I didn't feel so passionately about SET amps that people gushed over and I tried (845,211,300B, 2A3). I finally read a Nelson Pass article about distortion and found out that it's about an even split between people that prefer 3rd order harmonic distortion to 2nd order....Clearly my ears prefer the 3rd harmonic and that truly helped me make decisions about speaker choices and amplification. It was liberating to know that there wasn't something wrong with me for not loving SET.
As far as the DI's go, they are the perfect way to find out what camp you fall in (2nd order, 3rd order, mixture of both). If you don't know which camp you fall in, pick a representative example of both topologies at the same time (if economically feasible) and find out what your ears prefer.
