How come there is no thread on the RealityCheck?

Kana813,
When you refer to "jitter" in the following statement,

"the unit is powered by a switch mode power supply. The noise level on these supplies can increase jitter in digital equipment"

are you referring to mechanical vibration or to clocking problems?

Exlibris-

Yes, the high level of ripple noise from these supplies can increase jitter on the clock generators. Power supply noise can also effect the disk read functions.

...I'm simply protecting unknowing folks from shills pushing bogus and marginal products. Consider it a service from a concerned ombudsman. Thank you.

I'll opt for self-service.

Kana813,
Thank you; I'll ask my technician to replace the stock power supply with a battery PS.

Exlibris, I assume a rechargable battery supply. I would be very interested in what you find to be the differences.
