I currently have Zu Definition 2s---which to me easily compete with speakers in the 20-30k range. They are completely awesome for the money. While amplifiers are a bit fussy with them (I have tried 5 now), they are a lot of fun!
That all said, if I decide to upgrade to a true reference grade transducer in the next year or two, what options do you recommend? Clearly the Wilson Maxx3 and Magico Q3 are where I would start, but what others? I have heard the Maxx3 a year ago and found it very, very good. I should point out that I will not purchase an 80db sensitivity speaker that requires an arc welder to drive---therefore, no MBLs (which I don't care for anyways) etc.
Anyways, appreciate the feedback in advance. My amplification will be McIntosh 601s when released after CES. Preamp yet to be decided.
