As long as you're running balanced out, which it sounds like you are, you're losing little if anything by using SE in.

True.  I'm not expecting a huge difference.  But the balanced should be a hotter signal, once I verify that the attenuators are at 0 dB.  The specs in the manual don't list the balanced out voltage, but they do list the SE voltage out at 2vRMS. This should affect volume, if nothing else. I'm assuming balanced out is around 4 volts.
 
Besides...it's balanced!  I need to at least try it that way

Looking forward to what you hear but I didn't hear any volume change between SE and balanced.

I posted this in the other thread:


Just confirmed that the DAC-19's SE 2.5V output to the Liquid Carbon's SE input is the exact same volume as the HA-1's 4.6V balanced XLR output to the Liquid Carbon's balanced input listening to the Liquid Carbon's balanced output to my ETHER C. What sorcery is this? The wonderful phase splitter?

Set your phase(rs) on stun!! :eek:

Finally received my Carbon back from the repair center this week, and it's worse!
 
This amp is not only exhibiting the same problem, but now I am getting much more aggressive distortion in both channels (not just the left), and with all of my headphones, not just the Orthos. It sounded ok when I first started running it last night, but when I got home this evening (after running it for 20 hours straight), the distortion is really bad!

It doesn't matter how I am running it. Balanced out of my Emotiva DC-1, or directly out of my AK240, or iPhone 5C through the single-ended inputs. I tried my B&W P7s, HD800s, HE1000's….it doesn't matter. I also ran it directly out of my Meridian G08 and Esoteric DV-50 without a DAC. I used different power cords and different outlet in my home on different circuit breakers.

Ugh, that's unfortunate. I'm going to receive mine this coming week. Hoping that corners weren't cut just to ship amps out "on time."

Sucks, sorry, really frustrating (been there with other gear). Back to the shop.

I'm curious - what did the repair center state was the issue? And what fixes were applied?

Won't sore high on the old WAF scale (Wife Acceptance Factor), that's for sure! :)

I found this pic in the wild. The owner said they were by Dayton Audio. They look sexy!!!

I was also thinking of some rubber feet - something to keep it from sliding around.
I found an 8-pack of cabinet feet for $3.34, shipping included!
