Will definitely try out.<br /><br />Upsampling to 32/384 with digital filter off could certainly result in very interesting waveforms for the TEAC to play. Alas, I suspect my ears would be grossly embarrassed as to whether it would be able to hear differences :-).

As Frans put it, they don't trust measures nor graphs only their golden ears: "what do engineers know about sound anyway?".<br /><br />OTOH, HQPlayer is a very "different" kind of Anonymoushttps://www.blogger.com/profile/00068796379770931418noreply@blogger.comtag:blogger.com,1999:blog-4781727111866727703.post-40106621446877882402013-06-08T00:13:24.772-07:002013-06-08T00:13:24.772-07:00Thanks Javier.

F...Thanks Javier. I'll look into it in time...<br /><br />For now, working on some tests with Win 8 players and JPLAY like what I did with the Mac OS X players to see whether there are any surprises!<br />Archimagohttps://www.blogger.com/profile/08642574001287787545noreply@blogger.comtag:blogger.com,1999:blog-4781727111866727703.post-87611814349244843272013-06-08T00:05:47.740-07:002013-06-08T00:05:47.740-07:00Great article!
