AMR 77.1 cd player and your thoughts

I demoed a 77 version and I have on the wat a 77.1 version

Some questions for owners of this pce;

1. Anyone hear the two, if so what sonic differences did you hear between them.

The unit comes with a pair of IC's in rca configuration and power cable.

2. Do you just use these or have you done any comparison's trying other manufactures or xlr vs the rca sent for example, if so and what were the sonic differences.

3. What do have you placed under your unit for isolation and what were the sonic differences.

4. My unit is brand new so sonic wise during break-in what should I expect.

5. Does it sound good new right out of the box.

6. Any tips on break-in method.

7. Offers different filters, what do you find is your prefered setting while listening and why.

8. Hooking up an external pce such as an I-pad "which I would like to use" for example, what do I need to do and how does it sound in comparison to playing cd's. Taking into consideration I'm after best sonic results.

Thanks
