Dumb question... How can you agree/disagree if you haven't heard the T3 yet? Just curious.
I don't mean to offend.
Just my opinion or educated guess based on all the speakers I've heard and owned. I guess it's my logic.
Something like if A ~ B, and B assumes to be > C, then A must be > C, although I've never heard C.
No one is capable of listening to every single model.
I think it's a safe assumption that no PSB speaker is going to sound better than the Revel Salon 2, B&W 802 Diamond, KEF Reference, Linkwitz Orion, etc.
I've heard the PSB Imagine T2 & Synchrony One a few years ago. I thought the T2 didn't sound better than the Infinity P362, which I've commented on AH at the time of my audition. I thought the Synchrony One didn't sound as good as the RBH SX-6300.
I guess it's like how people compare speakers based on memory and not by volume-match blinded test side-by-side. People chose a "reference" sound like the sound of a live performance. Then people compare each speaker to this reference sound since most people will never get to do a side-by-side comparison of most speakers.
So just my gut feeling. No scientific proof.
I suppose it's possible that the new PSB T3 could sound better than the $25K B&W 800 Diamond, $25K KEF Blade, and $22K Revel Salon 2.
Again, just my opinion.
