Ah, the one of the joys of being an audiophile... the luxury of arguing over which great preamp is "better".
I have heard the Premier 16 (not a MkII) on several occasions, and I concur that it is a great amp. Without having heard them together, I would say that the Premier 16, Premier 17 and the CT-5 all share a very similar sound. I will leave it to each person to decide which is "best".
But I will add again that, IMO, the CT-6 has very a very similar sonic signature, just not as much of it. It is really a remarkable Preamp for the it's price on the used market. If one can afford one of the more expensive models, then please do so.
