I use Mogami Studio Golds, which work well for me. Recommended. Have not compared them ABX to others, but I find that the touted clarity and low end impact of tbe D90/A90D come thru fine.

I am using the Hart Audio patch cable https://hartaudiocables.com/products/tc-1-3-pin-xlr-patch-cable
Other good options are:
Periapt
Worlds Best cables (search Amazon)
Thanks, of all the options recommended only the worlds best seems easy to buy in the UK from Amazon. Just purchased two of those.

I asked the Hart folks what they use for cabling and they told me
“We use oxygen free copper from Mogami for all of our cables. All of the connectors are gold-plated” so I think this is a great option, as none of the Mogami Studios are that short (they are really designed as mic cables and the shortest ones are adapted as interconnects— but for DAC-Amp connections the shorter the better).. The nice thing about Hart is if you need a particular length cable they will make it for you custom. They are GREAT folks- I had a cable with a loose connection recently that I sent back on warranty and they not only repaired the one I returned but gave me another one to boot. Can’t sing their praises highly enough!
Same experience for me with Hart Audio Cables... These guys are providing excellent products and customer services.

Hi everyone, and apologies in advance if my question is too basic, but I can't figure out what to do.
The volume is very low, even at 99. Has anyone experienced this? Any guidance you can provide?
I bought a Topping A90 Discrete a couple of weeks ago. I'm using a Macbook Pro or a Fiio M11Pro as the sources connected via RCA to the Amp. I tried multiple headphones, including an Azure LCD2C and the Hifiman Arya. I checked the volume of the sources, and they are at their max.
I don't know whether I'm doing something wrong or the unit is not working properly.
I have a Chord Mojo, and it works perfectly compared to the Topping A90D
Thank you in advance.

So we can help you, pls clarify
1) how are you connecting the cable from the sources into the A90D?
2) what are the settings of the A90D (gain, HP mode)?
3) are you using LineOut from your source devices - for MacBook, are you using the ‘headphone out’ (seems so, since you don’t mention a DAC between MacBook and A90D, the more typical setup would be MacBook -> USB out -> DAC -> RCA out-> A 90D.
4) how are you connecting the HPs to A90D?
I’m guessing either your gain is too low on A90D for your sources output power, or your connections are faulty somehow.

For ‘gain’ there are 3 levels -low, med, high. What is your gain on A90D (must be set in the settings menu, there is no gain switch). Some sources need higher or lower gain1) mini plug to RCA cable
2) HP
3) Headphone out, I tried lineout from my Fiio M11pro and got the same results.

I'm only able to switch between L and H. It's in H, volume is still low 
Thank you for your patience!

Have you been able to get normal volume out using ANY source? Is it the same out of all HP outs (4.4 mm balanced, 4-pin balanced, SE out?) there have been some issues with SE out on the HPs, but mostly with the unit turning itself off not too low volume- there is a firmware update that needs to be uploaded from your computer to the flash drive in A90D while the unit is turned off.I'm only able to switch between L and H. It's in H, volume is still low
Thank you for your patience!
HOWEVER
I would advise you to avoid plugging in expensive HPs at this point till you sort this out- see post https://www.head-fi.org/threads/topping-a90-discrete-aka-a90d.963858/page-16#post-17111288 on this thread- directions for firmware 2.4 update follow.

Thank you! I have not been able to get normal volume using any source. I have not tried BAL out. I'll check the firmware.
Check whether you are on volume curve 1. Mine came out of the box with volume curve 3.

From an ASR post on the subject
“By pressing "B" on the remote, you can change this curves, and I was finally able to listen… the user manual provided on the internet don't have this information and states that the "B" button on the remote is an "invalid button"...so if you happen to have the same problem, just use the "B" on the remote.”
