I need cables for my 2 channel system

I agree 100% w/david_ten’s advice. The Cable Co. has a database on cable for equipment (based on user info, I believe). Do give them a call.

At the same time, there will be brands that "fly" under The Cable Co. radar. You might want to at least research some of these. They represent high-value offerings and won’t break the bank.

Power (for DAC & Pre-Amp) - Shunyata Venom (Actually, The Cable Co. does carry this line and has good pricing right now). Pangea 14SE power cords. Not everyone is in love with the larger gauge Pangea 9xx series but I think, for sources, the 14xx series is very good.

USB to DAC - I’ve been very impressed with an Oyaide NEO d+ Class A cable (Class A, not Class B). Noticeably better than an all silver Pangea and an all copper Audioquest I have.

XLR - Mogami Gold Studio Neglex Quad Microphone Cable. You can spend more, but why? Let your ears be the judge. In my system, this holds its own in the company of Cardas Golden Ref., AQ Columbia, Harmonic Tech Pro Silway II & Cabledyne Copper Reference. A killer bargain by comparison.

Speaker Cable - Clear Day Double Shotgun cable. Very impressed with Paul’s wire and prefer it by a good margin over Morrow Audio SP-4 cable. Others that are well regarded but which I’ve not heard: Signal Cable and Audio Art.

No guarantee what sounds good with my gear (or to my ears) will work for you.  Just some ideas to check out.  ALSO - Opinions about cable are like a certain bodily orifice. Everybody’s got one. Good luck in your hunt.

Sorry Mayor!  I'm clueless about that Type C termination.  I had to look it up.  See link here.

That might be a question to post as a separate thread on A'gon and/or to ask about over on the Computer Audiophile site.  Before starting a new thread though, enter Type C USB in the "search discussions" box and see if it has come up here.  If so, I missed it but then I always was a "late adopter".  Good luck.

I entered Type C USB Cable in the search discussions box.  Got a bunch of hits.  Thought the discussion here might be relevant and helpful...

Mayor - a caution...
I've not had much success getting responses to emails sent to The Cable Co.  Maybe that is just me.  On the other hand, dialing in and talking direct to one of their sales people (Stephen, usually for me) has worked very well.  They've been very generous with their time.  Good luck.

"Call"...i.e., use your mobile device for something other than texting, Facebook, taking selfie’s and other nonsense. Use it as a telephone and engage in a real time, person-to-person, spoken conversation. Weird concept, I’m sure.

Yes, I get that I should contact the Cable Store, but they are incentivized to sell me expensive cables.

The used market is great for bargains but it requires knowing a bit about what will work for you (your gear & your ears). The Cable Company is another good resource for getting grounded in "cable lore". Contrary to your concern quoted above, I have not found them to promote cables that are way above my budget.

Just about all my conversations with Stephen at the Cable Company include him asking, early on, about associated gear and what I wanted to spend. He then makes a couple of suggestions in my price range. Will even tell me if something worth considering is available at Used Cable.com. Yes - he might suggest something that is just above my proposed spend, but not outrageously so. I’ve yet to encounter any strong-arm, pushy tactics with them.
