A quote on GR06 & GR07 vs VSD1 comparison taken from LMUE FB page:
emphasis on the mids and harder hitting bass. But as someone who prefers a more balanced presentation, I would prefer the VSD1 over the GR06. In terms of technical quality, I feel that both are quite comparable. I hope this helps!
I still dont know whether to go for them or wait for VSD1s.
I've already ordered mine this morning. I didn't want to be in the position that you are in, because I knew that I would be going back & worth trying to decide on the deal and the deal would run out before I decided. I prefer being impulsive.
