I have NO experience w/ the 20 but do have experience w/ 50 & 100. In that light, I can confirm Lazarus' quick assessment above -- except of course the compression at VERY high (unnecessarily high IMO) volumes that settles in w/ the 50 whereas was unoticeable with the bigger model.
The 75-150 midrange driver is, of course, one of the best upper mids in production. I don't know which tweet they use (vifa in the older models?) but it shouldn't be difficult to find out -- and upgrade if you feel necessary.
I beg to differ slightly re, the pre: the bigger model was extended & detailed, the smaller one seemed less so -- both being somewhat limiting where details were concerned. I listened with an attenuator as a reference, so my comments ALSO reflect the addition of an extra circuit in the chain -- Lazarus is living with the pre, so is more experienced.
Oh yes, the sound: to be short, excellent.
