So essentially i can hard wire the switch part and use a normal 6 pin pot right?The extra space is for the rotary switch is side the pot.

Oh shit. Thanks a lot. That really helped.Yes, looking from the datasheet it's just a plain switch (but to be sure you could email JDSLabs)
Thanks, it's the El8 Titanium, i'm waiting for it to ship.. In that site cannot be identified the EL8's, anyway it's 98dB at 1mW, infos online says even 100 or 102dB x1mW, but it's only 98 Audeze says.. So it's 122dB in low gain, it should quite enought even if i listen very loudly sometime, but it says it requires 2,75 Volts rms, in Low gain Atom generate 250mW but i don't know how much Vrms.. I try to avoid High Gain on Atom because amirm on the review says on H gain the results were not as low gain, he didn't show us so i guess he don't wanna show the results Also paired with Topping d50 the total SINAD were 109, and cutted to 106dB (Don't ask me why! amirm says that), so i don't know if i would benefit at all the low gain instead of high..You would get 122 dbSPL if the headphones are rated 98dB at 1mW. If the headphone rating is 98 dB at 1 V RMS the max output would be 106.75 dBSPL.
[EDIT] I ran the numbers using a spreadsheet I have. Looking at your link I see that the website tool has a selection to identify the units. Which 30 Ohm headphones are planning to use?
Use the gain setting as low as possible. There is no such thing as headroom when it comes to gain setting. Headroom is set by the supply rail and the components themselves. You can have 6vrms input and output 6vrms at 0db gain setting. That's all depending on the input. In real life you use only about 1mw and hardly 10mw. The sinad of all frequencies at 1mw and 10mw is what's important. Don't be blinded by the numbers.Thanks, it's the El8 Titanium, i'm waiting for it to ship..

http://ohm-image.net/data/audio/rmaa-onkyo-dp-x1-24-bitAnyone here using a DAP with their Atom? I am thinking of using my Onkyo DP-X1 with the Atom .. Onkyo headphone out to Atom 3.5mm input. The Onkyo by itself has a hard time driving the Senn HD6XX. Does this sound feasible? Thanks!
I wouldn't worry about how you power it down....Newbie question:
What would be the proper procedure to shut down the Atom or any other amp using power-off button/switch? Would it be okay to relay the power line to the switch and back to the board or should there be any additional safety circuits to power down it gently?
Can someone help me, how much volume i can reach in dB with my headphone according to https://www.headphonesty.com/headphone-power-calculator/ With a 30 Ohm 98db in sensitivity with Low Gain? Looks like ATOM in Low Gain can reach max 250mw in Amirm measurements, (Tell me if i'm wrong) and i don't get the Vrms story, so don't know.. Maybe 122 dbSPL?
Well even with he6 or k1000, the power is enough. 2vrms at the input is good enough for both at 0db gain setting. And you can output more at higher gain or higher input. And distortion under such load will be low too.So unless you have new he-6se or old he-6, maybe akg k1000 - forget about anything else regarding power reserve. .

At the technical standpoint, where the atom amp falls short is the high frequency distortion(over 2khz) when using low impedance load(16ohm and less) and outputting high current. That's the limitation of circuits using lme49600. neurochrome hp-1 can be better but still will measure much worse than under high impedance load condition.
In real world, unless you are using 16ohm k1000 or to power an 8ohm speaker, you are free from any distortion.
Tho it will still has characteristic due to relatively high distortion with low impedance load like aeon flow, final e4000, the sound can be a bit bright, not much but still.
I guess you missed the point. The whole point was the ability of atom. Atom has 8vrms voltage output, and 200+ma current output. It's always the case no matter the gain setting is. Whether it's loud enough when listening to actual music, it's irrelevant. Of course you need to set higher gain when it's not loud enough while you cranking the volume to max.Forget about your 2 Vrms from the DAC during normal, nicely recorded tracks.
"The second percentage reflects the normalization adjustment being used. This is the amount by which the playback volume of the clip has been turned down to prevent users being blasted by sudden changes in volume in comparison to everything else. The value scales in proportion with the Volume slider setting.
The final value is the “content loudness” value, and indicates the difference between YouTube’s estimate of the loudness and their reference playback level. This value is fixed for each clip, and isn’t affected by the Volume slider.
So for example a reading of 6dB means your video is 6dB louder than YouTube’s reference level, and a 50% normalization adjustment (-6dB) will be applied to compensate. Whereas a negative reading of -3dB, say, means it’s 3 dB lower in level than YouTube’s reference, and no normalization will be applied, so the normalization percentage will always be 100% of the Volume slider’s value – YouTube doesn’t turn up quieter videos."

It is extremely relevant - this determines usability of certain kind of headphones with the amp.Whether it's loud enough when listening to actual music, it's irrelevant.
