A07XLA burn quality question

Soon i’ll be getting a A07XLA and got a simple question:
How good is the burn quality using the hacked firmware, when writing quality media (RicohJPN, Verbatim MCC, all 4x rated) at 6x or even 8x?

it’s my understanding the burn quality doesn’t change. Hacked firmware allows more features, tho. Also look into the Liteon 812s and the NEC model. Personally I’d be very interested in the 812s right now…
