Hi.

Actually, your PlexWriter (if it is comparable to the UltraPlex readers for the aspect of audio extraction) should really rip at 10x or even faster. With EAC and its secure ripping though, it should not exceed that by much.
The UltraPlex40 is able to rip audio at about 24x in my setup when in burst mode, and at about 11x when in EAC's safe mode.

BTW: You asked how long it takes me to rip one CD. That isn't at all a comparable measure, because some audio CDs are filled to the max (well, to about 64min) while most are only filled to 45-50minutes. That is a difference of >30%.
