Not sure why the upsample sounds better to me... My thought was that it was more due to the nature of the upsample being done beforehand vs. in realtime. Similar to the idea of why (in general) ripped redbook sounds better from a PC hard drive vs. a CD player. I dont really think the dbpoweramp algorithm is the best (SSRC). I have switched to soX using foobar. It seems to be better, and it tests a bit better. The algorithm fascination of late is more academic than anything else, although its surprising that math makes a noticeable difference. I was trying to get some discussion generated about the upsample phenomenon in regards to the Transporter - hence the "advice you give all the time" about it. From the limited feedback I have gotten so far, it appears there is some agreement to upsampling redbook to 24/96. Thanks for the info! I havent looked at the data sheets yet. Do that tonight over a couple of beers and some music!
