It is very on topic. Since the OP Roofles might want to know the what and why of things. It helps understand why the audio nuts mentions things. When he makes his purchase, he will know why he bought it.
When it comes to ogg. Anything past 128 is ok for medium sized players. Once you start moving past 128 you eat up space. So if you do not care about the top most your ears get. With a trade off of a smidge larger files. Do not worry about it. 191.7bit files will show as 192... I have ogg that are 190 and sound just fine.. Some players will round and show odd results. Go by your ear and file size. The 190 show as 192 in one of my players and Windows. Linux shows the true bitrate.
When I am at home with no cars, busses and folks talking loud. I want FLAC. On the go. The SQ is not all that and it matters more for how many I can skip past or select.
