Anyone HEARD the qol 'signal completion' device?

Koestner, creative thinking; I like that. I suggest you do that experiment. Let us know if you fry out anything in the signal path! :)

I don't have one, let alone two of them. I would think one of these dealers could do this. I also don't see the risk of "frying" anything by hooking up two line level devices, that reportably have no gain, in series. But, you never know, so whoever does this should wear a fire suit.

I will be posting my impression of the Qol this weekend.

Kclone those are all options for placement of qol unit. Just choose the one that works for you best. For me after the pre-amp was better. If you put it before amp you will only have qol working for that one source. after pre-amp all sources have option for qol.

I finally took some time and listened to the mono set of the Beatles on cd through the qol unit. I set ARC pre-amp to mono and qol to mono. The improvement is just as profound as with stereo. You have to hear it to believe it.
