-So dear Dan: For Lavry da12: Please supply remote with abillity to switch between inputs Hi, Thanks for your feedback. Regards Dan Lavry

Quote: Originally Posted by jkeny This is one area where I believe Mr. Lavry is wrong - reflections are caused by impedance mismatches usually at both ends of the cable (where transmitter & receiver reside) so BOTH short & long cables will have reflections (it has nothing to do with...

5 nsec of jitter is terrible! First on a very basic level: For a 16 bit system, you have a "quantization grid" of 65563 levels. For a say +/- 1V signal, each quantization level is 2V/65536 = 30.5uV (micro volts). The fastest analog signal within 44.1KHz system is 22KHz full scale sine...
