Hi, from what has been said I deduce that if you happen to play 24 bit material and turn the volume down by 48db on the tp digital regulation you loose exactly the detail that a 24 bit recording has and a 16bit doesn't. You will end up with the quality of a 16 bit pcm well and off you go. Enjoy!

Andy I always imagined that by dumping the bits frame by frame into a buffer and then reading them out aysnchronously but with a very high-rez/low jitter clock, the end result would be good. Provided that the buffer never underruns then I see no reason why this wouldn't work. Since the sampling

I must be missing something...the ORIGINAL sampling frequency is a given...let's say it's 44.1 kHz. So all you need to do is read those frames out at that frequency. Why exactly is that so hard? Assuming you never run out of frames to read. As far as I can understand things, the whole clocking
