I have done quite a few times. Audio civilians always prefer the SACD layer, 100% of the time. And they had never heard of SACD or DSD until I told them and had no technical knowledge of electronics/loudspeakers.If you haven't already, (just for fun) you might try "testing" one with the other on yourself and others and see if anyone can tell the difference. Again, I would not be surprised if certain CDs sound as good or even better than certain SACDs due to the nature of the music and/or the quality of the recording.
OK, I'm up for this. Although I have my preconceptions. It would be nice if we could paste the links into your post on this thread. But that would mean all examples would have to be MP3 format. I'm not sure if the MP3 bitrate or sampling rate is fixed here on HUG for the embedded player, but I suppose 48k 320kB (or more?) may conceivably play. Thus far, all MP3s have been at 44k. Worth a try?...that I can convert any hi-res material down to 16/44 and, under blind conditions, you will not be able to tell them apart with any kind of statistically valid consistency.
The whole point of the exercise is that we reduce the hi-res to the lowest common denominator; 16/44.If the HiRes files are 24/96 wouldn't it be more appropriate to make the LoRes files 16/48 rather than 16/44.1?
Already considered...read message #12 in this thread!You also need to consider that the true 24/96 file is likely to have considerable content above 20kHz. Anyone with a file editor can load them up and take a peek. So a great idea so long as there is some basic blind test housekeeping
And it isn't just cables. To my ears ( and to the benefit of my wallet!), I also now find that even external DACs are of no audible value. One of things I needed to do in my systems was to connect the mac to the Denon. I was busy researching - which USB DAC is best etc etc - when I thought I should first just run a 8 GBP analog wire from the mac's headphone socket to the RCA aux inputs on the Denon amp. With the mac not injecting any static or hum into the signal, I find that to my ears, it sounds just as good as a CD played in the Denon. There is a reduced volume of sound, I suspect that the current from the mac out is a little lower than usual, but the denon amp has enough head room for my needs in the room to take care of that. It is once that is done that I do not realise the difference between the two sources of course. Another feature of this connection is that the volume can be controlled at the mac as well, though this has its downsides as well.I'm not surpirsed. I think you've nailed it on the head. Cables need to be decent not exotic / expensive (i.e., they need to be undamaged, of appropriate gauge, and designed satisfactorily to get their jobs done).
Speaker placement and room acoustics are vastly more important IMO and experience.
