Zu for Pass Labs?

thanks again! May I know what differences are between Omen MKI and DW II ?

Found this is an old (er) on-line review ...

The Omen Dirty Weekend (Omen DW) is effectively a reduced-cost Omen Mk II. Both are two-way floorstanding speakers of modest dimensions (36” tall with a 12” by 12” footprint, 54 pounds). They present a 12-ohm load with efficiency claimed as 97 dB and a bandwidth of 35 Hz – 22k Hz. The Omen DW uses the same drivers as the Omen Mk II, which are Zu’s zu260frd/nd 260 mm nanotech/paper composite full-range driver and the Zu/ASD:1001 tweeter assembly. Both use the Zu-Griewe box/acoustic loading technology. Zu uses more advanced and expensive drivers higher up its product line. The cost reductions achieved for Omen DW relative to the Omen Mk II come from parts substitutions in internal wiring, crossover capacitors, and speaker terminals (the Omen DW does not include the Zu-B3 input connector). Like all of Zu’s speakers, the Omen DWs have a slightly pro audio look, which appeals to me visually but is a bit plain and utilitarian. The speakers are well made where it counts but they are not fancy-looking speakers-as-furniture..

Thanks guys, here in Spain I can get these ones:

Dirty Weekend II for 1.500€ brand new (hickory)

Omen MK II for 2.500€ brand new (Hickory)

Omen MK I for 1.100€ in kind of ruby. 

What would be best choice? is a real improvement, DW from Omen, and Omen II for the other two? I just know I loved my Omen MKI, and dunno if the other two has different sound.

What are the really expensive speakers you said you have listened to? 

expensive at least to me, for example:  Audio Physic Avantera III, ATC SCM50 ASLT…
