There are several factors I will take into consideration before sending in my 3B for the upgrade.
It will never be a true 3-B3, because it was an upgrade and will carry the X at the end of the serial number.
The warranty will not be reinstated for the full 20 years. It would be really cool if Bryston would re-up the warranty, but it doesn't appear that will happen. The 20 year warranty is a huge selling point.
Where will upgraded units fall, price-wise, in the market place? Of course they will be worth more than if they remained SST2. But, will the market price them at or near a used non-upgraded cubed amp?
I think the price increase, while I'm sure necessary; will be somewhat of a turn off for buying new. However, due to the amount of components that must be replaced in the upgrade process, how far off would the upgrade be from buying new. If the price isn't far from buying new, the upgrade, in my opinion, isn't worth it. With the weak Canadian dollar, I see an additional price increase in the future.
