Two years ago, I acquired a passive pre-amp switch box for use in evaluating speakers under blind conditions. The two channel signal from a Marantz 7703 is fed into the passive pre-amp, with an "A" and "B" left/right signal then feeding an Axiom 1500-4 power amp. The power amp has 4 channels, and is a quiet, powerful, neutral amp. The passive preamp allows for level matching at the preamp level, and instant A/B switching between the speakers in question. All speaker evaluation is done under blind conditions. A direct comparison between the DI's and Legacy's is quite doable, blind, and without an agenda to necessarily pick a "winner", but rather to describe the relative characteristics of each speaker without knowing the identity of the speaker. I have an email into Eric to see if he is interested.
