I vaguely remember a thread where someone mentioned that the ES10 had excellent filtering capabilities (unlike the ES20) -- that even if not using it directly to record anymore, it might be handy to use to pass through a signal that you want to record on the DVDR. I'm pretty fuzzy on those details -- does anyone remember that feature? It was an unadvertised capability of that particular model or vintage. The ES10 was a pretty inexpensive recorder, but I've been told it's worth hanging on to.
I have a really old E55 boxed up, too (my first Panny) that was put away when it started exhibiting recording problems when it got toward the end of the disc-- (I suspect it was in serious need of a cleaning). At work we have a barely used combo 35 that was quite a nice machine. Trying to hang on to that. Lately at home I've only left my EA38 hooked up, mostly for audio passthrough to headphones and occasionally dubbing to an external recorder (I dont like the dubbing feature). Even tho I'm not using them, it just doesn't feel right to let these older models go , especially when the old stuff was better made and more reliable than the new!
