I've heard the Vivid Audio K1. My impression is that it's a very decent speaker in terms of throwing a deep holographic image and believable soundstage, and sonically the highs and mids are very refined. What it lacks, however, is an engrossing bottom end.
The K1 actually has four 6" woofers per speaker, with two on the front baffle and two in the rear. I'm not sure how much the speaker placement in my audition affected the sound, but these speakers were placed at least 10 feet in front of the back wall. I asked the dealer if that would affect the bass negatively, but he said no. I tend to believe, however, that the low-end performance would have improved with more realistic and practical speaker placement closer to the wall, particularly since two of its woofer are firing from the rear.
In this demo room, there was actually a pair of Eggleston Savoy nearer the back wall, so it wasn't possible for me to ask that the K1's got moved back, and of course, any room set-up for more than one pair of speakers are generally not ideal. One positive thing about the K1's bass performance, however, is that the bass that it did have was tight and fast.
Overall, I think this is a very good speaker if you can accept that its bass ouput is on the lean side, which can be addressed with a sub, of course. The mids and highs are impressive, however, and to be honest, this speaker to me is more about looks and design. It has high WAF factor and if you have a "modern" looking room/home, this will fit right in. Really, it's a blend of luxury hi-fi and a showcase piece for the room. From what I understand, you can also choose any color for it like the Wilsons.
Haven't heard the Giya yet, but would love to. If it's like or better in the mids and highs than the K1, but provides substantial bass, then I think it would be a winner.
