In case you didn't know...

...using that type of interface adds a lot of electrical interference inside the component:

-- There has to be a microprocessor running at all times to control the screen. This means a high speed digital clock is running at all times.

-- The display itself has multiplexing (switching the display elements on and off rapidly) or scanning. Either method creates high-frequency electrical noise.

-- The touchscreen sensor also has scanning, both vertically and horizontally. Again, more noise is generated

All of this creates a considerable amount of high-frequency noise. Some, but not all, of this noise can be filtered out. The remaining noise generally degrades the sonic performance of the audio circuitry. The degree of degradation is difficult for anybody but the manufacturer to determine, as you would need to listen to the same unit with and without the extra noise-generating circuitry.

But in the end, if you are happy with both the sound and the interface, then you should be happy indeed.
