Amarra for iTunes at RMAF...

You never know. Changes to a PC's BIOS are claimed to have a burn in time. I have better things to test than that one. But when I first tried Amarra, I heard it as different, but was not convinced it was better. It seems more like an EQ difference at first. The more I tweaked the whole Mac thing, the more it became clear to me that it was indeed better at capturing the full harmonics of an instrument or voice - and without it the harmonics were slightly grayed-out and flattened. I think this was due to me improving the performance of the Mac, but hey, there may have been some burn in, maybe...

I worked at one time for the pc board manufacturer American Megatrends on bios systems, the burn they are speaking of is a hardware burn in to make sure that there are no hardware failures within a certain period of say 24 or 48 hours of intense tests being performed on the board.

Well, again I agree with your comments. I too first thought it sounded like maybe some EQ tricks were going on. I am not fully convinced yet, but I just ordered (this morning) 4GB of mem for my mac mini Core2Duo and I will be doing further tests after the mem arrives. I am beginning to think it may be more than just an EQ change taking place, further listening sessions are required.

The BIOS burn in comments I was referring to have been made by guys making CMP PCs, and their claim is that to assess a BIOS change you need to make the change and then let it burn in. This is after the hardware burn in you refer to.

Just saw that Amarra 1.1 is out. The readme says it supports Apple Lossless but not the ones generated from Max. Well, I am bummed since most of my hi-res tracks are just that. I was going to place an order as soon as Apple Lossless support is in but now I guess I am going to wait some more.
