In 2010, I audiotioned the more affordable JBL K2 S9900 ($40.000/pair) hoping it's performance would come very close to the JBL Everest DD66000. Although the S9900's without doubt are really great, they were far from as great as the DD66000's. In fact the difference was so huge that if I am to upgrade my speakers (in 10 years time, maybe
), my living room will contain the DD66000's.
In near future, I will audition Tannoy's flagship, the Tannoy Kingdom Royal. The expectations are rather low, though, as an audition of the less expensive Yorkminster was disappointing (missing the JBL punch and bass). I also hope to visit the person with the Sonus Faber Elipsa and MC 2KW (with an open attitude).
Best speakers ever heard: JBL Everest DD66000.
Other excellent speakers: Infinity IRS Beta (unfortunately not for sale any more), Soundlab Majestic (think it was the Majestic... Great mid range and upper range. Novice bass), JBL K2 S9900 (great).
