Upsampling 16-bit / 44.1 Khz Music To Enhance It

Hi all, just found this site (very interesting !) and am quite pleased to be a new member.I am quite interested to try and up-sample my normal music files (AIFF/WAVE - 16 bit, 44.1 Khz) to higher specs eg. 24 bit, 96 Khz or 192 Khz using Mac OS X based software that is specialised to do this kind of stuff. Does anyone know of any really good up-sampling software for the Mac ?

Once I manage to upsample them, I can burn DVD-Audio discs and play them through my Denon DVD1940 player which is compliant with DVD-A and SACD discs, it has a 192 kHz / 24-Bit (Burr-Brown DSD1608) 8-channel Audio D/A converter. My DVD player is connected to my A/V receiver (Onkyo TX-SR606). This is a good receiver but has no sonic up-sampling ability like some of the higher end Receivers such as Cambridge Audio which have the Q5 up-sampling technology (Highly rated) by Anagram Technologies of Switzerland.

I am using full range KEF speakers and have spent quite a bit of money on getting decent interconnects to maintain good signal quality between devices in order to prevent any loss in sound quality.

So, all in all, my intention is to be able to up-sample all my music to 24 bit / 192 Khz using the best up-sampling software on the Mac.I could then burn the up-sampled files on DVD-Audio discs for play-back on my player.

Has anyone attempted this ? Any suggestions on good Sampling conversion software for the Mac ? - I came across "Sample Manager" by Audiofile Engineering. They use a sample converter made by Izotope which apparently is supposed to be very good. Does anyone know about this or have any experience with it ?

I know the fact that decent audio up-sampling technology does make a difference, I just need input from audio experts or enthusiasts.

Any advice and input will be appreciated.
