Pass Labs X250.5 or X350.5 ?


This would be the last piece of equipment needed and I would like some help in deciding between the 2 of them. What I have now :

- Room size > 40sqm
- Source > EMM Labs CDSAse
- Pre > Pass Labs XP-10
- Speakers > Usher Be-10

I would of course preffer the X250.5 because of the price but if X350.5 will be notably better on my system, I will struggle to get this one !
fuscobal
Usher Be-10 is not that power hungry but I guess better low frequency control can't hurt ! Bass driver would be the Eton 11" (11-584). Sensitivity would be 89db !
Thanks guys. Bought a X250.5. With the difference in price between the 2 I will treat the room for better acoustics !
