PSB Platinum or Synchrony one ?

Own both (PSB dealer), if it were me I would go with the Synchrony One. Not only is it the current model, but it sounds better imho. Not that the T8 was bad or anything, it was anything but, the Synchrony One just takes it to the next level in refinement.

I disagree I listened to both and felt the T8 has better bass response and better control on the treble with back firing tweeter. Also build quality seems better on the T8. I was able to buy the T-8 as a blemish model for a bit more than the synchrony from a dealer in S. Cal.

both are incredible and on paper the Platinum 8 would appear to outgun the synchrony one...that said the synchrony one is one of the finest new loudspeakers i've heard. its an absolute throwback to the neutrality (or balance across a wide bandwidth) of classic new england east-coast designs. psb hit one out of the park and it will compete with even the crazy-expensive esoterica.

The T8 is certainly not bass-shy and is a fine speaker, but you have to consider that the Sync One is much more room friendly in most cases.

As for build quality....Dude, the Sync One is much better imho. Ah, to each their own, though. ;-)
