The legendary pre-ringing is something that should be a non-issue with DACs that work correctly. Once there were some false implemented hardware that caused intermodulation of the pre-ringing into the audible band. This is no problem anymore. Unfortunately it is easy to show as fancy picture that even can be "improved" with magic filtering. This is audiophile tuning at its best. A graph that shows anomalities that dispaear when filtered. This must be better... Also remember that this ringing normaly happens above 21kHz and there are several reasons it shouldn´t be a problem. Even think about that many tweeters don´t produce much content there. In reality nearly all non-linear filters will cause lots of time smearing even starting at frequencies around 10kHz that surely change the audible signal but look soo good for thbe pre-ringing picture. I seldom take marketing writings but this is what Benchmark thinks about it and i think they are right: http://www.benchmarkmedia.com/discuss/forum/general-conversation/apodizing-filters I doubt you can produce some signal that causes your Transporter to It should be possible to produce a file with a huge amount of pre-ringing with a "maximum phase" filter to do some abx. If you like i may have a looky how to produce such a file. ------------------------------------------------------------------------ Wombat's Profile: http://forums.slimdevices.com/member.php?userid=4113 View this thread: http://forums.slimdevices.com/showthread.php?t=96098
