Vivid Audio alternatives

My first instinct would be to try YG Acoustics.  Best of luck. 

KEF Reference line. KEF Blades if you have the space to the outside of the speakers.  I had the Kiya 45 in mind for my space but thought the KEF Reference line was close to it for lower cost.

Vivid is coming out with new new monitor speaker that may pass your WAF test.

@beetlemania thanks.  Have you heard TAD's Evolution One TX?

@ebm thanks. I'm like a Queen's servant here haha!  will also look into Avalon

@soix thanks, will check out Hailey 2.2 which seems to fit the bill, size-wise

@yyzsantabarbara thanks, will check out KEF reference.  Interesting to see S12 model;  though I'm not sure whether it can deliver to Kaya 45's level .

Estelon (YB) could be an option. Same drivers (Accuton). The looks are also pretty. High WAF.

@gabbabe I've not heard that model, just the Reference One and CR One.
