Well every place is a tradeoff of some sort. Quiet and solitude isn't desireable to everyone. I'm sort of isolated and the area isn't a tropical paradise. This is a high desert area so in the summer it's hot during the day and cold at night. In the winter it's cold during the day and really cold at night. We do see sunshine about 300+ days a year, and even in winter it's warm on your back. It was -20 the last few mornings though.... Maybe if I got a 950 I could harness that to chill it....

[/B] Yes, but specifications _DO_ live in a vacuum - they are an _absolute_ measurement of the performance of a particular piece of equipment. Those specifications are published. The 950 does NOT meet those published specifications for noise. It can't get much more black and white than that! If Outlaw is having a hard time replicating the noise problem, I offer a simple 3 step procedure: 1) Walk to the warehouse. 2) Pull a 950 at random from stock. 3) Measure the noise.

This wide swing in noise floors points to poor design/manufacturing QC in my estimation.
Possibly some cheaper parts with >20% tolerances might be getting onto the PCBs. In certain units these tolerances add up to an optimized noise floor in others they just make the noise floor terrible.

SoundHound -
Just curious, when you measured the S/N on the 950, was the selected input shorted, floating, loaded w/ x ohms or....?
What is common practice?

What is common practice? I measured mine with shorted input, open input, and 10K ohm input termination. The results were pretty much the same. Standard practice varies between all these. Shorted input is fine if you take into consideration that the input will be driven by a low impedance source. I also measured with both wide bandwidth, and a 20Khz low pass filter, in order to sort out out-of-band noise like clock bleed etc.

Going off-topic for just a moment. ...or the soothing crackle of forest fires, and sometimes the cheerful sound of riots. Man, you triggered a memory. I was living in West LA during the Rodney King riots, and I'll never forget that constant burning smell in the air whenever I stepped outside my apartment. I don't remember ever smelling that with forest fires, no matter how close they got. Lena, here in Los Angeles we've had fires, mudslides, earthquakes, riots, and even a 200 car pile-up a couple of days ago. Waiting for plague and pestilence to complete the cycle. Best, Sanjay [This message has been edited by sdurani (edited November 05, 2002).]
