[Empeg-general] Typical Newbie questions but...

[jcboeckl@empegbbs-noreply.merlins.org]

I guess I'll ask it anyways.  

I've been reading here for a couple weeks and learning all about the RioCar.

I plan on getting one but for reasons of my own I plan on keeping my current HU, at least for a while. (Sony C90 ES)

Anyways my real questions is for those who have used the XA-300 or XA-107 to connect the Empeg via the Unilink input.  

1) Does this unit degrade SQ?
2) Any downfalls I should look into?
3) You still can control the Empeg Unit regularly and aren't limited to CD changer interface right?  
4) It should act just like I had a Line Level Aux In correct?
5) Anything else I should know?

Thanks in advance for the help?

I am Truely  impressed by the amount of information this site holds.  And it makes me very eager to buy one of these units.  I love tinkering with things and from the sounds of it there is a world of adjustability with the Empeg/Rio car.

Also where is the best place to purchase these units from?  Also is there any way to buy a HD'less unit and add a HD of my own?
this seems to be the cheapest place I have found thus far:

Thanks again
