There are many relatively inexpensive scientific instrument versions with 50 ohm outputs. I could find none with a 75 ohm output, as needed for optimal impedance match with 75 ohm digital audio input as used on the Esoterics. Through a web search I found posts and screen shots by an engineer who measured a degraded 10Mhz waveform caused by reflections between mismatched 50 & 75 ohm BNC impedances. That was enough for me to pony up the added $$$ for the SRS.
Rubidium Clock
Can anyone advise whether an Esoteric Rubidium clock would improve the sound on my Esoteric X-01/D2 player? I have been told "not much since it is a one box." But the reviews have seemed to indicate that the upgrade in sound quality is quite apparent. I am aware that some upgrades are very small in their ability to be heard, others are like a whole new piece of gear.
Any advice is appreciated.
