While designed to best complement the VMS Mic system and the Preamp modelling software, many users found that the transparent nature of the preamp works well with other mics. Others have said that on its own, it's one of the most transparent sounding preamps in the market today.


Some users found it too complicated and fussy.


While its primary purpose is to be part of a mic and preamp modelling system, the VMS-ONE holds its own as a standalone preamp. If you want an absolutely transparent preamp for your studio, the VMS-ONE is a great choice.

Although this was previously on our recommended list, there are now more highly rated options available which you can see in our guide to The Best Microphone Preamps.
