Soundhound,

Have you measured the S/N? If so, what does the S/N ratio measure on your modified 950? You measured the S/N to be worse on my unmodified red dot 950 than on yours. But the hiss was louder in your 950-based system because your speakers are horns and are more efficient than mine which are direct radiators. Anyway, I hope the modified 950's have consistent S/N readings rather than some being measurably better than others. I'm no expert in these matters though.
