hey guys, I'm really new to cabling and would like to look for a cable for upcoming 1964EARS-Quads. Obviously am looking for something that will upgrade the sound quality, but am putting quite a bit of emphasis on cable size (not thick and bulky, I've seen pictures of the Null Audio Lune and it looks REALLY THICK), flexibility (I heard most custom cables like Twag were quite stiff), and if possible some color choice other than black or clear.
 
Apparently, the custom IEM itself has nearly drained my budget. Therefore, I went and set my budget to a max of about $150.
 
As I was browsing Unique Melody's website, I looked into their website and found those Beat Audio Cables. I saw their "Blues" and the "Supreme - Rose/Elegance/Sanity" cables and they physically look exactly like what I'd prefer, plus their price at about $99-139. However, I am oblivious of how they perform in term of sound quality and signatures. Searching in Head-fi didn't help much as well.
 
So, I'm just posting this in hopes that anyone out there would have had experience with these and perhaps can give me some valuable advice/suggestions on these cables.
 
How much of an upgrade are these cables over the stock cables that custom IEM brands usually give?
How do these cables sound in terms of sound signature? I believe you can compare them in terms of any universal IEM, I'll likely figure it out.
Is it worth the upgrade? or should I just stick with the stock cables and rather save the money unless I'm going for something like the Twag?
Are they really thin and flexible as how they look in the pictures on the website?
OR, is there some other cable brand or someone making DIY cables that may be a better choice than these?
 
Sorry for the big bunch of questions, but really am interested in these but not so sure whether they are worth the input or not. Thanks in advance though
