So could HiRez downloads sound as good as SACD?

I'm not a computer-based audio person, just an SACD fan.
Is this possible or is it already around in some fashion?
What kind of hardware or software is needed?

I thought this lossless stuff was just meant to replicate redbook CDs, not to be at the DSD level. Am I wrong?
Thanks.

I did a little format shootout using high rez files from the 2L label. They sell SACD / BR Audio 2 disc packages and have the same material downloadable in 96/24 and 192/24. So using the exact same source material, I played:

96/24 flac into bridge / perfectwave DAC
192/24 flac into bridge / perfectwave DAC
SACD on Marantz ud9004 universal player
High rez 2 channel PCM on the Blu Ray disc (not sure if it is 192/24 or 96/24)

Although the Perfectwave DAC is a better DAC than the ud9004, I consistently prefered both SACD and PCM on the ud9004 over the flacs. SACD and PCM was a toss up. However, the differences are all fairly small.

To me, the quantum leap comes from going multi channel. No comparison with 2 channel, whatever resolution. Exact same content, I prefer the MCH SACD over the Blu Ray.

The format that gets me closest to the live experience is MCH SACD. Try Chick Corea's RendezVous in New York MCH SACD. To die for.

Edorr - you are comparing apples to oranges. Your SACD player versus the PW DAC. Not the same as comparing the two formats.

If your SACD player had a DAC in it with external inputs that could be driven from a good USB converter, this would be a better comparison, but still not quite apples to apples.

A better comparison would be a 44.1 track ripped from a CD and played on the PW DAC compared to the CD played back from the transport feeding the PW DAC.

Steve, I agree. There are a lot of variables here making true apples to apples difficult. The closest I can think of is to get the Ayre Universal which plays all formats on silver discs AND had an asynchronous USB input, and then do the expirement I did. This would take hardware differences out of the equation. All I can say is this. To me MCH SACD is closest to the musical truth I have expienced. In fact, I am listening to Michel Camillo SACD "live at the blue note" as I am typing this up. Sheer delight.

Differences between high rez formats are small, and still tend to favor
