I heard there are some folks out there who believe the Sound Devices 664 sounds better than the 688. Does anyone out there share this opinion? I'd love to hear some comments on this and some explanations as to why the 664 might sound "better".
[I currently own a 633 and have spent a fair amount of time working with the 688 (which I love). I am planning on purchasing the 688 for the additional channels, ability to use the SL-6, Dugan/MixAssist, and to have EQ control with the CL-12. The 664 would give me only 1/4 of those features.]
