I guess you could say that..........but because i have not had extensive use of the Amek range i would be ill qualified to make that assumption.Sometimes pre's surprise you.
Perhaps in an area you hadn't considered using it in,and then do,you find out the unit does a good job of capturing the source for you.
Most things i have thrown at it it seems to do a good job.We have some descent mic's in our arsenal which help the cause and ofcourse the voice your micing needs to be of a good standard.
I like the flexibility it has,eq,comp,phase rev,+48 etc etc and if you were considering buying or trying one out,providing you purchase at a price that's rewarding for you,you'll find the pre amp will equal that feeling.
