Beyerdynamic T 5 P is different class to Fostex TH 900
with Fostex Hp P 1 sound quality with Sony PHA 1 more fuller sound , more detail and more clarity and has better bass detail .
overall TH 900 more enjoyable than T 5 P
Thanks Rudi. Here in Australia not too far from you I think, T5p is currently half the price of TH900! Maybe T5p is closer to TH600? All the best to enjoy your head-fi gear.
