Their replicas vary in quality. Eg their 606 is way off, their 808 really doesn’t sound like an 808 and their 303 needs modding to sound right. But it seems the simpler they are, the more likely they are to nail it, the Model D sounds very good and their Pro-One clone is actually excellent.
I would (and have) bought Korg synth reissues over the behringer versions but I’m not going to say no to a £200 minimoog!
