I'm using a £1100 oppo pm1 (planar magnetic one) and to my ears it's on the same level with some 2-3K phones i've tried. Without blowing my own trumpet i played violin for over 10 years and my ears are sharp. The pm1 blows away some lower priced phones but not all. Quote from a fellow member on pm1 thread last July. Just bought an Oppo PM-1 on eBay. These headphones are really something else. In the past I've owned Focal Utopias, HD800, HD800S, etc. and I don't remember enjoying their sound signature like I do the PM-1's. On the well produced CDs e.g. Paul Simon's Greatest Hits, the instruments sound realistic & the subtle background percussions can be heard clearly. Best headphones I've heard. I also remember Rob using nighthawks which cost £500 with blu2/dave which costs £16,500. They were his favourites. Need i say more. I do fully agree with you however that tt2 owners should invest as much as possible into hi-end cans so i'm definitely not disagreeing with you there. When i save around 2K i'll go shopping for quality phones to compliment my pm1/tt2. No rush though. Of interest i'm hoping my pm1 will be a collectors item in the future as many are saying it will because oppo no longer make them.
