The proof that more drivers don't mean best sound quality (3 BA EM3 VS JH 16 for example).... to say "600 USD for a 2 BA IEM'" is a shortcut... all I can say is that I am happy with them and that for me, they are mor natural than all the Iems that I owned and also the W4, (that I also own at this moment), with better treble energy and timbre, better precision, with better "sub" bass, better depth and dynamics...
With the PFE 232, a free pair of PFE 022 is given... sell it 100 USD and the final price of the PFE 232 will be closer to the new W4R's price...for me that I live in Switzerland (also for those living in Europe), no shipping fees, no customs taxes...
