hi, so have the players now since about 4 weeks in use. Einwandfrei- can no m2ts! But that was it for now with the shortcomings! But it sounds as CD players very well! When I say this I do not mean = not bad, but it sounds really nice, I überlege- my Sony CD player completely eliminate, these plays Philips (connected via analog RCA) -almost on the same Level that means something. Have not determined the best ears, but experienced and also not the worst! mkv files = no problems, but absolutely great (in my opinion) is: it displays CD text, the display player without TV! I überhaubt not seen or heard it überhaubt a BD player can! This can not even to mention many CD players, DVD players. In addition: you create, for example. an audio CD and press play and it is music. Not only TV on and select the drive, but simply play class. Philips indicates max. Compatible External Hard Drive Size 160 GB !! Does my non-manages both a 2.5 achieved (500GB) and a 3,5er- (1.5 TB) properly, to ask! To image I'd write nothing- (CLASS) - which have other colleagues already done enough. Beautiful metal housing and high-quality appearance to a more than fair price. Having previously been some Philips products gehabt- (not all of them were great, but this is 7500 mk 2 tips device- a nice evening mfg John.
