I'm sure you're right. But I bet that the good Dr. didn't want to deal with blown transducers of an HD800 or HE1000 or LCD-3, if the Liquid Carbon were to fail "dramatically"....

I originally had one of the last 20 units, but since they were delayed for so long Cavalli offered me another amp (serial number in the 300's). They said they inspected it before they shipped it. By the time I received it I had already decided to go with another amp instead so I immediately sold it without opening it.
Now the user who bought it from me is saying there is massive channel imbalance and after speaking to Cavalli they agree that the amp has an issue (they say a few other amps have had similar issues so they know what to fix already). So now the user has to send it back and wait to get the amp back. I'm curious as to why that wasn't noticed when they supposedly inspected it?
Anyway, I know none of this is technically Cavalli's fault but IMO he should never deal with this manufacturer again. He should either find a new one or stick to making amps in-house. All conjecture at this point though.

I had one of these problem units. The imbalance/distortion did not develop until several hours into burn in, so it's likely the unit was inspected fine at the time, and the problem revealed itself later. Good news is that the repaired unit sound ds great at 200 hours, and seems to be improving still.

It's upsetting when this happens in a private sale. I had it recently with a DAC I sold on unopened. The buyer found a tiny blemish on the front panel and rejected it, which meant a lot of wasted postage costs on both sides.
I think Cavalli has made fairly clear that he will be having no more dealings with this manufacturer. In fact, I wonder whether his recent silence on the matter might indicate that the relationship is now in the hands of lawyers.
I just hope that we don't suffer any longer term reliability problems with the 'good' amps. I've got to the stage where I'd miss mine badly if I had to return it for any repair

I have one of those amps with distortion on the volume knob. I e-mailed Alex and he promised to cover shipping both ways. He received the amp and has fixed it and I'm waiting for it to be sent back to me. Once I receive the amp, I'll burn it in again and see if the problem has gone away completely.
How do I find out if I have channel imbalance or distortion? I'm only able to use it single ended so I can't test it balanced yet. With 3x gain I hear the music very slightly with the volume on zero. With 1x gain I hear nothing on zero though.

I'd put this in the "if it sounds good, it is good" category. If I think there is a channel imbalance, I usually will listen to something mono-if the signal is off to one side or another, something could be off (mono should image dead center for all instruments/vocals).
This helpful post by Joe Bloggs has a more scientific way to evaluate this, I've downloaded the software, but haven't tried it myself (he was responding to by bellyaching about a ciem that has given me channel balance problems on The Discovery Thread).

You just need to pick up Sinegen and run sine sweeps with the CIEMs in your ear. Beats any external measurement system every time. Picks up your own fit issues as well as driver problems. (of course, the two would get conflated in the output, but fiddling with the fit yourself quickly rules out #1)

I also have channel imbalance . There is also a slight hum on no volume. Tried four pair of headphones and all the same
Will contact Cavalli and see what they say?
This is after 50-60?hours burn in. Wasn't there at the start.
Bummer this as really started to sound good.
Man that was quick. Just got email from Alex at Cavalli in under ten minutes. Talk about customer service. These guys could teach a lot of British company's a thing or two about keeping there customers happy.

Unless the volume of your left and right channels are way off it's unlikely that you have a channel imbalance.
It's not abnormal to hear some volume with the knob at zero with 3x gain on. IIRC, I believe the volume level at "0" with 3x gain active would be about 63db below full-blown source volume. It may help you to think of the volume knob as turning your source down as you turn from right to left.
If I understand correctly, the volume range goes something like this:
1X (no gain)
-78db from source volume TO about 98% of your source's volume output.
3X (+15db gain boost applied)
-63db from source volume TO about 98% of your source's output plus 15db.
I am the the buyer of Maconi's unopened LC....I do not blame Maconi he is a gentleman and Cavalli responded immediately to the situation and the amp is on the way back to him .......to describe the problem, when i listened to my balanced cans through the LC the sound was primarily coming through the right channel with the left channel barely audible and the music sounded completely off...it was as if i was only hearing a portion of the music and it was simply out of phase or balance being the best way to describe it....I went back and forth between the LC and the mojo without the LC and it was like night and day with the LC impossible to listen to.....immediately it was apparent there was something wrong and after i exhausted every possibility of cable or source or power cord issues i contacted Cavalli and hopefully when it is returned to me all is well......it is however quite frustrating
When I got mine it had distortion like white noise playing. I sent it back to get fixed and it sounded great. Then last night when I went to listen to music, apart from me even considering if there is channel imbalance I am getting this distortion throughout my unit. It sounds pretty bad. I am currently asking for a refund because I do not want to ship it back again if it messes up. I just want my funds back.
