Looking for comments on the Vivid Kaya 45

I just recently demoed the 45 at a local dealer and was very very impressed.   I'm trying to find reasons not to buy them (not counting the cost) :)

I would love to hear feedback from owners (including previous owners, or other folks who went through listening sessions) of them; specifically what do you like, any dislikes, what else did you compare them with, etc...

My current speakers are Spendor D9s (which I'm a big fan of) and my previous speakers were Magico S1s.    I really liked the resolution, speed, and imaging of the Magicos, but found them to be fatiguing on bad recordings, lean in the midrange/presence region, and limited bass (but very good bass quality). 

I find the D9s image almost as well as the smaller S1s, are not as resolving but don't lack for detail/resolution and have a much fuller midrange/mid-bass along with very solid bass and dynamics.   I'm not looking to replace the D9s as much as I was just curious what was out there I haven't heard.

I thought the 45s were extremely well balanced, with more resolution than I heard with my S1s, equal speed, a more detailed/open presentation yet, lots of deep clean bass, and a midrange that although leaner than the D9s is definitely more full and I think offers more natural tone than the S1s.

I have a 12x17 room so I think they would fit and work fine; my only reservation is maybe the slightly lighter midrange presence than I'm used to now, but they are so clean and lifelike I really felt like you hear what is on the recording with them.   Nick Cave, Johnny Cash and Tom Waits all sounded great with them, super clean but incredibly life like.

I currently drive the D9s with a SimAudio 740P+Pass XA30.8, so am hoping the 30.8 would be able to drive the 45s to satisfactory levels.   I had an X250.8 with the S1s and don't really want to upgrade amps again if I can help it.

Anyhow, any comments welcome by folks with hands on experience with these...

Cheers
