Don't use a splitter cable. You need a DAC with multiple outputs or something in between that gets you another output, like a preamp (which the Magni 3 has, so you could go DAC -> Magni 3 -> preamp out to Little Dot MK2). Although with this setup you would not be able to listen to headphones out of the Magni 3 and Little Dot simultaneously.

I also used splitters and plugged RCA cables into them:

This gets two amps (tried MCTH, EC, ECP) working with the same DAC simultaneously.

Okay quick update, I've experimented with a few setups and I'm not certain the Y-splitters are going to work.
I have tried two different Y-splitters connecting the Topping D30 to the Schitt Magni 3 and the Little Dot MK2 and then driving AKG K7xx's. The Little Dot MK2 has no issue with this setup, I can't tell any audible difference between it being split or not. The Schitt Magni 3 is the one that has the issue with it. When I do direct RCA from the DAC to the Magni, it drives the K7xx's easy on low gain. When I split it, it struggles to drive them which results in the audio quality being less than ideal.
I'm new to this so someone who is educated in this realm could probably explain why but I cannot. Here are the two products I've tried:
Splitters:

https://www.amazon.com/gp/product/B01CT68CRU/ref=oh_aui_detailpage_o07_s00?ie=UTF8&psc=1
RCA Cables (I tried different ones to see if there is a difference, I couldn't hear any)

What I am saying is that I have tested in a few ways... I've used the two different y-splitters switching them out without touching the volume knob. Using 2 different RCA's and Y splitters. The volume is lower and the audio quality seems impacted. I would say it's not as vivid as when compared to when I have the RCA going straight from the DAC to the Magni 3. Now we are not talking drastic and you're right, I can just kick it to high and there would be no issue. My concern is that I don't want to ruin my equipment if something is going wrong.

So my solution is that I've ordered some more Y-splitters and RCA cables, and will try it again when they get here.

Don’t use a y-splitter. There’s risk of interference and amplitude drop. If you’re going for a true A/B comparison, grab a sescom switch. They make the for all types of I/O.
I also would advise against using a mixer as it will add quite a number of variables into your signal before it goes to your headphone amp. If you need simultaneous play, get an active audio splitter.

I wanted to recommend that one, but I didn't like that each output had its own control (also note that the control is volume not gain / they may have mislabeled it). If the idea is to have simultaneous copies of the same signal, like the original request, I would advise against it. But, if you need the flexibility of controlling each output independently then that definitely will work. Like if you needed to go out into a pre-amp, you would probably turn the gain down (although that signal flow could introduce more noise)

Y-splitter.
Just be certain that your splitter cables are lower impedance, as in large gauge and equal gauge to each amp so that you have good electron flow to each.
I have a rig set up so that I can listen to my speakers and my headphones,(open-backed), simultaneously, which can be an absolute nirvana experience.
It's kind of amazing.

Sadly it doesn't seem to be working for me... See my other post for an update. The Little Dot has no issue with this setup but the Magni 3 doesn't like it.

has anyone suggested a schitt sys ? use the output as an input, then you have 2 outputs. http://www.schiit.com/products/sys

coltblueYeah but that's a switch which wouldn't allow me to listen on two amps simultaneously

Like others have said, y-splitters are fine. Just be aware that one amp can interfere with the other one(s) it shares the connection with. Some amps short their inputs when turned off, which can cause severe distortion in the other amp. Generally most amps are well behaved, but if you do run into that issue one solution would be to use a switch to swap between two outputs. I do this for my Cavalli Liquid Carbon X which seems to distort the other amps in the chain.

I had the same dillemma with pretty much the same equipment as yours as well as headphone choices.
(But using a schiit modi multibit and no k7xx.... 6xx and 4xx not yet shipped, so using my old hd25-1-11)
I used this:
and so now I only need to plug and unplug headphones to hear different amps.

Hiroyuki_SawanoGoogle rca y splitter (image search show plenty of these)
https://www.musicdirect.com/connector-upgrades/audioquest-hard-y-adapter-rca-splitter-1x-male-to-2x-female
They seem to have better looking and different angled ones than the ones I'm using.

Looking for a gaming/content audio setup
Hello! I'm looking for recommendations on audio setups. I'd be planning on using it mostly for gaming. Preferably I'd like a pair of large closed back headphones since I have a big head and jaw. I'd also like to hear myself through my mic with mic monitoring. As far as budget goes, I don't really have one. But under 600$ would be nice. I can go higher if needed. The audio setup would be connected to a high performance PC. Thank you in advance for any recommendations!

What would be a good portable Dac/Amp to use with my HD6xx and Sony Xperia 1 V cell phone?
I am new to this hobby. I purchased a HD6XX and plan to use it with my Sony Xperia 1 V cell phone, that has a 3.5mm jack. I was wondering if I needed a portable dac/amp or just a portable amp and if so what would one recommend? Any assistance one could provide, would be greatly appreciated. Kind regards, Haz

Invest in Balancing my HD6xx headphones?
Hi... I'm a songwriter/producer. I have Drop Senn HD6xx HPs. I just bought a Topping L30 II SE HP amp to enhance my monitoring. It honestly sounds pretty good. The audio interface I'm using (an Audient iD22) has balanced outs. For those of you who've listened to the HD6xx using balanced amps and cables, do you think I should invest in that kind of setup to take advantage of the Senns potential?

Should I exchange the PC38X for better headphones?
I bought the PC38X headphones FOR GAMING and they are great, but I have NO use for a Microphone since I don't do competitive gaming and I was wondering if there were better headphone options at a similar price without a headphone, where (presumably) more of the cost was put into making it sound better. I also find that my PC38X don't get quite as loud as I would like and I was wondering if a cheap amp like the iFi Go link would draw a little more volume out of my phones. https://www.amazon.com/dp/B0BN6MM822?psc=1&ref=ppx_yo2ov_dt_b_product_details I went with the PC38X since it was considered the best bang for buck headphones. I care most about using spatial apps like DOlby Atmos and DTS Headphone:X. Suggestions are welcome.

Hello, I just joined, primarily for the audiophile products. Looking at purchasing the NHT C3 speakers for our new living room. Space is about 15 feet wide by 33 long and they will fire long ways. Space is just for general listening, music room with all equipment is downstairs, so hoping they will fill it with sound nicely. Cheers.
