Need upgrade advice

Well, this is the year of the speaker upgrade for me! My old trusty KEF 104/2s are ready. I currently have KEF Reference 104/2s, KEF 100 center, KEF Q surrounds. Velo 12" Sub. I'm looking to spend as much as $8K for the main pair. Since I've been a KEF guy for some time, I will definitely audition the KEF reference 205s. I originally purchased the KEFs because I love the mid-range of these speakers. However, I was recently in a HT store and listened to a pair of Sonus Faber Grand Pianos. These speakers sounded fantastic and I could really tell the difference in how tight they were compared to my old KEF 104/2s. Heck, they are even "cheap" in what I was thinking of spending. I will also be listening to the SF Cremonas. On the audio side, I have a Sunfire TGIII and Sunfire Grand 5 channel amp. Will use about 50/50 music and HT, but would like to lean to the Music side. I'm going to be taking my time in auditioning many speakers before deciding. Help me make a list! Thanks. SJ
