Hello i like to say i am a complete beginner at this and im wondering if i can connect
PC --------> usb/dual optical spdif splitter --------> to 2 kali using each optical in, OR xlr between the kali's first than optical from one of the kali to the usb optical. All this exercise is because i have buzz noise interference coming from the kalis when using rca to 3.5mm into green jack in the back of the motherboard i don't get the noise when using the same jack with my headphones only with the speakers so it might be the cheap rca to 3.5mm cable. Audio is onboard alc897 if it matters. The noise changes when i scroll and watch youtube and becomes unbearable when playing games like CoD. I am open to any other alternatives.

Hi @toni1v9! Welcome to ASR.

As per the MM-6 user manual, I would do PC->Toslink->Left MM-6->XLR->Right MM-6.

i see how does UT23 stack against AIYIMA DAC A2 the aiyima has its own power doesn't use the usb so its less likely to pick up interference noise or it doesn't matter ? just wondering since its in the same price range

usb/dual optical spdif splitter
Cool! I didn't even know they existed. I think it can be connected as you described above with two Toslink optical cables, each to one MM-6 speaker. Unfortunately, then the volume control with the remote control will be separate for each speaker - so you have to press twice :)

I'm using the UR23 for measurements and it's been great.
I confirm, very good quality and probably the cheapest for this type of use. Although the usb/dual optical spdif splitter is very similarly priced and does almost exactly the same thing.

I asked the same question directly to Kali previously. Here are excerpts from the e-mail conversation.

ME: I am interested in buying a pair of Kali MM-6. It has digital inputs like SPDIF and Toslink. I am thinking about the following set up and I would like to know if this works.

Toslink output from streamer => Toslink splitter (1 in / 2 outs) => Optical cable to Left and Right units => Set dip switch so that left and right channels are assigned correctly to separate left and right channels

My question is; does a remote work to mute and control volume on both speakers when they are both connected with Toslink input?

KALI: Thanks so much for reaching out! When you use the digital input (such as optical in your case), you only need to send it to your primary speaker. That unit will then split into L and R and send the second stereo signal to it's partner speaker via XLR. You won't need a splitter, basically. The remote will control the primary speaker, which in turn, will then decrease the volume or mute the partner speaker as well.

ME: Thanks for your answer. I am aware of the connection method you described below. However, I’d like to avoid Analog-to-Digial and Digital-to-Analogue conversions as much as possible. That’s why I’d like to feed both speakers with TOSLINK instead of daisy chaining the secondary speaker with XLR connection. So, my question is; if I have two identical optical signals in TOSLINK and feed both speakers, can I control the volume and mute on both speakers with remote?

KALI:
Understood. The Toslink setup you're describing should work, but it would be an unsupported use case as this was not specifically tested during the design process. Also, the remotes are speaker-agnostic (and the speakers are, I suppose, remote-agnostic,) but have a fairly narrow dispersion pattern. So it's possible that you'd turn one speaker up/down but not the other. Which has the potential to be a real pain.

I understand the desire to eliminate as much latency from DAC/ADC as possible, but I will say that users have thus far been very pleased with the performance they get out of the system with setups outlined in the user's guide.

Topping D10s outputs via Toslink and SPDIF at the same time with USB input. So, one can connect toslink to one side and spdif to the other side. It can serve as a USB to Optical/COAX converter.
