I don't have an LCD-3 or a Noble K10. You can find my full AF180 review on InnerFidelity, though: http://www.innerfidelity.com/content/audiofly-af180-ear-monitor-reviewed#WgxC36rHiFbDJiQp.97 Someone asked this fairly recently. I think we settled on the Philips Fidelio S1/S2 and Havi B3 Pro I being good options to avoid hiss with such sources. They're a little more neutral compared to the warmer PortaPros, but not vastly different, and hiss shouldn't be a problem at all.
