Oh I see!! Well I find the Vetta the best but none of them are very good in my opinion. The 'master' compressor on the front panel however is absolutely brilliant, very transparent and clear.
I didn't get on with the SMX dual comp personally, I found it quite harsh and obvious sounding. Useful as an effect maybe, but not something I would want on all the time.
I will move the post!
Cheers
