Pass Aleph-3 questions

david, as we've prewiously discussed, both here and *off* a-gon, i tink perhaps rogue's claim of 100 ohms output impedence for their 99 preamp is a bit optomistic. and, yer speeks' efficiency of 92db means that the aleph-3, which should be able to handle lo-impedence loads, will be able to drive *sustained* 107db levels w/o clipping. pretty loud, imho - especially in a real-world-sized room, where it may be even 3-6db louder. as we discussed off-list, assuming the pre's output impedence *isn't* the problem, perhaps yer speeks are hardening/compressing at these loud levels...

defeating the speaker outs w/the headfone input doesn't necesarily indicate a problem w/output impedence imho - it could yust be a conwenience thing - when yure listening to headfones, it could be assumed that not wanting to disturb others is a possible motivation for the headfone-listening, & therefore ewe woodn't want the speakers active when listening thru the headfone yacks...
