Ditto on the SACD, really still the best format for HD sound anywhere.
I occasionally try formats, but nothing seems to match-up with SACD

None of these work well for me

Arcsoft does not work with Windows XP x64
WinDVD does not work with windows XP x64

PowerDVD does work with Windows XP x64, but to upgrade from the OEM version included with the drive and actually take advantage of the new features they want another $85.00 beyond what you already paid for the drive. This reminds me of the bait and switch days where the promise one thing but you get another.

"For a small fee..."

I tried the upgraded version from PowerDVD, but fail to see anypoint in upgrading. The video looks identical (as in perfect picture) and the sound options still seem fail to impress me at all and they just give you surrond sound which has been out for years. So, still not sure why I should pay another $85.00.

"I'd love to listen to hi-fi recordings on blu-ray. Seems to be more practical than SACD (dsd issues, expensive players) or DVD-A (dead format"

Listen should be the key word. It's about the music. Can't say how much more practical Blu-Ray is than SACD. Expensive Blu-Ray players, more expensive discs, sounds like the same song.

I have never heard a TrueHD, DTS-Master audio or Dolby TrueHD music cd...anybody? So how would I know it's more practical or even better than
SACD?

DSD issues have been player related. You can buy amplifiers that support DSD via HDMI now (Yamaha RX-V663 for instance). Best deal on A DSD capable player..OPPO 980H DSD via HDMI $170.

So the only thing we are really missing is a Blu_Ray player that does what the OPPO 980H does plus the Blu-Ray side of it. Somebody needs to build me one of these so I can actually compare all the all the HD audio formats to SACD.

Know of any Artists that have a disc in all these formats?
