I just got a Quantum 2626 and regrettably it doesn't come with a TB3 cable.
Now my Quantum 2626 will be at least 1,5 m away from my Mac so I'll probably need a 2M TB3 cable. and as ya'll know, those are quite expensive.

Will a 20 Gbps TB3 cable suffice, or do I really need to shelf out €90 for a 40 Gbps TB3 cable?

I just rode a long support train with Sweetwater and PreSonus on this, and I'm going to give it you in a nutshell. I have had a Quantum 2626 for a couple of months now. At least once a day, it would randomly fall into fault mode and freeze up (froze up my iMac on several occasions, too). All the front panel input LEDs would suddenly glow solid red for 5 seconds, and then the unit would be effectively dead. Only a restart would bring it back. Ultimately, the problem was determined to be the cable. I was using the StarTech 2-meter passive 20 Gbit/sec cable that Sweetwater bundled with the Quantum. On the direction of PreSonus, I swapped that cable out for an Apple 0.8-meter active 40 Gbit/sec Thunderbolt 3 cable, and all my issues vanished. The cable, as it turns out, is a critical component in the use of an interface like the Quantum 2626. Find a way to get your 2626 closer to your Mac, spend the 40 bucks, and get that cable.

It's not the cable you want, it's the cable you need.

Hey there!

I have a 2014 Mac Mini with my 2626 12 feet behind me in a rack. I am using the 5.5 meter Corning TB Cable and it works like a charm! A lil pricey but it was the only cable available that runs that length and longer. There is a link on the webpage where to buy them.

Good Luck!

It is Fxxxxxin absurd that this doesn't include the correct cable in the box.

I'll be returning it in disgust.

PreSonus, I had to wait a month and a half for my Quantum 2626 because it had been on backorder, so when it arrived I was that much more eager to use it. I was extremely disappointed that a Thunderbolt 3 cable was not included. Charge a little more if you have to, but you really should include everything needed to get started right away. A set of screws to rack it would have been helpful as well. If not, then at least inform your resellers to set their customers' expectations accordingly. Thank you.

Yes, it is very dissapointing that Quantum comes with no TB3 cable. It's a bit like a car seller would sell cars with empty tank. And you would have to come to a dealer with own gasoline canister.

Shame on you PreSonus! After 2 weeks of waiting for your interface now I have to wait another few days for my cable to arrive.

At least write it loud and clear somwhere on your page that you are skaters and do not add cable - so that every buyer can prepare properly!

Strange, and very unfortunate. That sounds like the usual problem you would have with stingy, and arrogant Apple wanting to take your 1st born for a unrefundable deposit. Has PreSonus fixed the problem yet? I was interested in the 2626 down the road, but I wanted to find out if they can be paired with the Fader8. Can anyone answer that here? Thanks.
