@prof -- I listened to the Perspectives yesterday for almost two hours and really had a chance to run through a range of different LPs and hear how they responded. Music ranged from UHQR copies of Bill Evans (Portrait in Jazz) and Miles Davis (Kind of Blue) to the first Dire Straits album to an original copy of "Blues and the Abstract Truth." While the room was quite different than mine and the source table and arm much better, I was impressed on all fronts.
I was not able to hear the Pearls as this is a new JA dealer and he doesn't have a pair yet. But with the size of my room and the fact that I have a downstairs neighbor, I am not convinced that I will be able to take advantage of the Pearls (especially at 3x the price including the jumpers I would need to buy.) I suppose I will hear them at some point, but I suspect spending the "saved" money on cables and treating my room will produce a bigger improvement all around.
Still waiting to see some decent photos of the wood options before the order is placed, but I expect to be able to do my own review shortly. On a slightly related note, I was able to see and hear the new Kuzma Safir arm and was really taken by its role in presenting the Perspectives. More on this once I lock down the speakers!
