I received my Atom amp two weeks ago. I measured the cups with a db meter and pink noise yesterday.
There is no channel imbalance on my unit.
This is maybe not as good then measuring with a voltmeter, but i cant hear a channel imbalance either.
For what its worth.

That's one of the benefits of hand-matching parts, or using higher grade components, why some of the Alps pots are so expensive. Better yet, go to the ultimate volume knob, a stepped attenuator, giving perfect channel balance and lower noise at every position....
To be more precise, it is volume potmeter component dependent.
There is a considerable difference between individual potmeters.
So much so that Jeremy (garage 1217) has to bin about 30% of all potmeters he buys for his amps as they vary too much in value in the lower part of the adjustment range. He built a simple test device to check for this.
It has to do with manufacturing tolerances of this relatively small mechanical part.

The look the same as my measurements. The line shows deviation from 0 dB (ideal). Volume is at max and then reduced step by step. I don't know how the steps represent actual volume control position.

However, nobody should expect that in a $100 amp. The Atom's volume pot is not bad, especially for the price. It has a poor/cheap feel to it, not liquid smooth, but it is well balanced from 8:00 all the way to max. I've seen analog volume knobs on $1000 amps that were worse.

I had to fashion a very short extension for the potentiometer though.
Would you elaborate on how you did it? I'd like to "upgrade" the knob too
Give it a whack. . . .seriously. The relay is sticky. JDS suggested this. If it continues to stick, then contact JDS.I have missed the last 20 pages or so of the thread but I am wondering about the Atom not turning off that was mentioned towards the early part of the thread. Is that still a case with anyone?
It happened to me once after a couple of days of owning the amp but didn't happen again until today. Now it doesn't turn off at all, the knob click to off position but the relay doesn't turn off. If I remove power it obviously powers down but powers on as soon as power is reinstated.
I am just wondering if anyone has a fix?
(I am in EU and the amp was delivered to me by a colleague, so I can't send it in to JDS).
Because the price of something does not determine its performance. The Atom is built with plastic housing, etc., thus it is less expensive than the O2. But, it outperforms the O2 on objective measurement tests. In fact, it outperforms amps 3-4x more expensive. So, are you suggesting that JDS charge more for the Atom than the O2 as to justify its performance level?JDS Atom vs o2
Why is the jds atom amp cheaper than the o2 when everyone says that the o2 is obsolete and that the atom is better in every way?
What is better in quality? NwAvGuy described in detail all the steps that led him to the development of O2, so I personally have more confidence in him than jdslabs
If jdslabs had the same detailed development blog, there would be more trust.
Mr. PorchSong, you did not pay attention to the second part of my questionBecause the price of something does not determine its performance.
