No comparison to Gen, I recently did one myself and it's incredible. Make sure you get the new 7035 model with inside AR. You won't regret it.I was happy with the xtal until I put it side by side with my VSF Sub and suddenly it didn't look too great, what are people's recommendations for a xtal replacement on Clean Batman? Ideally I'd go gen but looking to see what else is out there? Anyone put a Prof xtal in their Batman/Batgirl?
