milpai, the DI's will work very well in a small room as they perform very well at low volume levels. If they are physically too large that's where the electron comes in.
kalali, I hear you. I call Eric the mad speaker scientist as he's constantly inventing new models. Probably more models than needed but it's in his blood to create. I've not heard the OB Sigma's but have heard nothing but good things about them.
wgutz, interesting point. I've owned Tektons in both the satin and automotive finishes and can't say there's any sonic difference. Like you I have a decent amount of quadratic diffusers in the room, maybe they lessen any reflection issues.
