Not sure what the limits are, but I keep putting my Emotiva XPA-2 into protect mode.
Here's the setup:
Pioneer Elite DV-46AV (using as a CD/SACD player)
Dodd ELP pre
Simple enough right?
Using different source material, I can't get the Dodd's volume much more than 50% before the XPA's protection mode kicks in (scares the crap out of me everytime ). Usually on the right channel. Normal listening can be had around 25-30%.
I also had this happen at least twice with an ipod as a source, but the Dodd was up at about 75% while the iPod was about 75% as well.
It's pretty loud, but I think it should be able to go louder, or have I reached the LSi9's limits somehow? I left my SPL meter at work-I'll bring it home and see if I can get a reading for when it craps out.
I've changed my ICs, my speaker wire, and the tubes-no relevant changes. The amp is directly connected to an outlet via a 14awg basic power cord.
When I hook the iPod directly to the XPA-2 (no pre), I can't get enough volume to kill it.
I used Carried Underwood - Wasted, and I think even Floyd - DSOTM.
Other than that, a hum, and a high noise floor-it sounds BEAUTIFUL!!
I also have an XPA-5 that I can test with, but initially at least, I'd rather not haul either beast up or down a flight of steps (again). ;)
Thanks for any feedback.
