e...Hey guys. recently,i want to buy my own recorder,and i love 664,it suit for me.but I have some questions.The biggest one is the amp--the sound quality.Somebody told me is a mixer so you don't compare it with SD 7s recorders.but I want to know the 'distance' between 664 and 744(788's DR is too good).I read their spes.I found some different.but i don't understand THD + Noise what it specific is....here these are:788 THD + Noise Mic: 0.004% max (1 kHz, 22 Hz–22 kHz BW, gain control down, -15 dBu input) Line: 0.004% max (1 kHz, 22 Hz–22 kHz BW, gain control down, +16 dBu input)
664:0.09% max (1 kHz, 22 Hz–22 kHz BW, fader at 0, 0 dBu output)
The different is 20 times more?!
Please Forgive my poor english...and thanks for reply...
