...here's my 2 bits:

SACD is evil. yep. Why you ask? ...because the DSD format removes (or severly curtails) any ability i previously had to digitally process the music. You see, digital signal processing likes to handle data in the PCM format... real numbers you can play with. But DSD is just a mash of 1-bit noise, and a good deal of DSP has to take place to extract useable data from that bitstream... so add more digital manipulations and some decent resolution loss if you want to do something digitally with this stuff.

Now here's something even funnier: SACD can dramatically reduce the cost of a CD player by moving all the digital filtering and delta-sigma modulation (normally done by chips inside your cd player) into the studio. So now, your CD player just has to spit out the bitstream to a very simple DAC chip. Say goodbye to audible differences between different DAC chips and digital filters, and say hello to higher-priced equipment. Of course, the manufacturers will say that the higher price is justified by the higher quality of output, but I know that the chipset will actually costs much less than a conventional CD player... (at least if SACD ever becomes the new standard).

This is just one example of a disturbing trend I have noticed where big companies are pulling the wool over consumer's eyes and selling less for more under the veil of "high tech". As we move into the age of sophisticated electronics, new products are consistently moving farther and farther beyond the comprehension of the consumer (and, notably, court judges...), and so it is increasingly easy for corporations to pull this kind of stunt whereby the consumer only sees the end result, and can be heavily influenced by marketing propoganda.

Thanks for tuning in.

Nice option, combining the DF1704with an analog volume control.
