Hey Charles,
I think you hit the mark here, we all like different things about musical reproduction. I let a good friend of mine borrow my Lamp L4/G4 and he preferred his Metrum Octave in his system. I was surprised, but can understand why, because music is personal and our ears like different things. Some prefer the hyped hifi sound and others like an easier going natural sound.
It was difficult for me to let go of that Big Six, because I was very happy with what I was hearing from my system. But the opportunity arose and I wanted to hear what the Lamp's DSD sound could offer. It appears Matt likes the Big Six I sold him, and if he does get connected with the Lamp sound like I did, it will be hard for him to let go of its natural sound. It has "soul".
Steve designs the Overdrive, so it's understandable he has bias. Even reading the review it wasn't clear the reviewer chose his DAC over the Analog DAC, more like each had a different presentation that might suit certain listening preferences. To say that the Lamp would need an dressed up OR5 to have a fighting chance is a bit premature, especially since he hasn't even heard the Lamp sound.
Btw, I need to hear that Yamamoto DAC someday! I will send you an email after I get more hours on this Big 7.
Sorry if this is derailing your thread Matt, didn't mean to. You are a lucky camper man, have fun with the shootout!
