Hugo 2 and WA8 would be insane. I am looking forward to hearing about that.
regarding, the WA11 vs 1Z, I cannot say anything about that because I am not impressed with the sound of the Z1R with the 1Z at all. I still think that the Z1R needs more power (I do agree with you on that). When I got my 2C, out of the 4.4mm, the WA11 is miles ahead of the WM1Z (i think it's not fair to say that since the 2C is planar). U definitely need to hear the WA11 to believe. detail wise, it a tiny bit less than the Hugo 2, but sound and price-wise, the WA11 is very hard to beat. (I've tried the 2C and Hugo 2 at a local store).
I will try the Z1R with my WA11.
