Does it make sense to go for Pass 0.2 ?

Hello, I currently have Pass preamp X2.5 with Pass X150.5
I was offered a deal to swap my X2.5 + amount of cash for an used Pass X0.2.
The question is : does this make sense considering the power amp I have ? What will I gain if I did this move ? What will change ?
In addition to the above, I have cd player Cary 306 SACD as a source and Avalon Opus Ceramique as speakers.
Cheers and thank you for your input.
Mike
