First of all, I'm a hobbyist with "home studio" for mastering, but here are the results of my blind test:
1) Ones that made me feel good: URS TDM, Impact and Liquid mix
2) Ones that had the best feel between bass, drums and the vocals: Impact, URS TDM, Waves RTAS
3) Ones that gave the vocals certain "star factor": URS RTAS, Waves RTAS, Duende.
4) As an all round performer: Digi Impact.
As I own none of my top three choises (and Impact is only available in TDM) I think I'll just have to save enough money for URS or Waves
Most of all, thanks for having the time to do the recordings!
