I know it's not the kind of thing that you usually try during a test drive, but has anyone sampled the standard audio system?
There's a massive difference in power output between that and the Meridian, so I suspect that standard might be a bit feeble,
I've driven an XE with the default audio, and wasn't impressed. I currently drive an Audi with the Audi Sound System (also an upgrade), and must admit that sounded a lot better than the XE system.
Glad I ordered the Meridian
