Hi all, as the title says, dumb question. I'm running a JTV-69 into a HD500x into an Alesis Alpha 112 powered speaker ("500w continuous, 1000w peak"). After a while I wondered how much clean headroom I really had and ran the right 1/4" out from the HD500 into my old Drive G120 (120 watt) combo amp. So at that point, HD500 left 1/4" out into passive DOD A/B box, into Alesis, and HD500 right 1/4" into A/B box, into Drive combo amp. A/B'ing the Alesis vs. the Drive combo, it seems like the combo amp has a ton more headroom than the Alesis. Obviously I'm not much of a gearhead. Any opinions? Notes: -I don't have any complaints about the HD500x into the Alesis, other than that the Alesis is hissy and I'm going to return it and get an Alto or JBL etc instead. Normally I run the HD500x XLR out into the Alesis XLR in. -I had the Alesis a few days before I saw on the interwebs that the Alesis XLR/line input volume knob is misleading in that it's intended to only go up to "5" for line input before risk of blown speaker, but the XLR volume can go up to 10 theoretically. In my trials with the HD500x into the Alesis I am watching the clip light and clipping is not a factor for either the Alesis or the Drive.
