Hey Matthew,
First of all, I want to say, all you people that like to give Matthew a hard time for changing gear should lay off. If he wants to change amps every week, what's it to you? Sheesh. Big deal. That's part of the fun.
Now, regarding the NAD C545, the build quality seems cheap to me. It's mainly the drawer mechanism that makes me say this. The drawer is cheap plastic (as are most CDPs), but the action is loud on mine and does not inspire confidence. Also, my first 545 broke and had to be replace. Now this new one is suffering from ejecting the disk while spinning into the tray, which can damage your CDs. However, I think I've found out how to avoid that by avoiding certain actions.
I will say that NAD cheerfully serviced my CDP and then replaced it without a problem, so the service was good and they are responsive to support issues.
I will also say that the C545 sounds fanstastic. Last week I purchased a rega apollo and after lots of listening, the apollo sounds closed in with rolled off highs compared to the open sound of the NAD. I'm trying to decide what to do. I definately like the NAD sound better than the apollo. Could be that the Apollo will get better with time though. I definately think the apollo's fit and finish is head and shoulders over the NAD. I really dig the top loading mechnanism and the door action is just plain sweeeeet.
Where I live you can buy 2 NAD C545s for the price of 1 Apollo. So I'd say, it might still be worth buying the NAD for the great sound quality even if the qaulity needs improvemen. Also, there are obviously many happy NAD owners with no problems. You might not get a lemon...
