If there is balanced 3.5 cable is it much better than 4.4?
4.4mm is better. There is nothing superior on 3.5mm balanced. The 3.5mm balanced was not mandated by any organizations, unlike 4.4mm
Obviously! Why can’t companies just fixed it to a specific size. How many cables and termination they want me to have
The 4.4mm is different. It is not Sony to invent it, but they adopted it first out of the newest Walkman and signature system. The 4.4mm is adopted and mandated by JAITA, audio standard by Japan engineering or so. Everyone who uses the 4.4mm have to follow the mandated standard of the terminations and so on. Unlike 2.5mm balanced, or 3.5mm balanced, these 2 have different ways to configure cables.
Simply put, 4.4mm is here to stay, and will be mandated with it 1 single cables termination just like XLR-3/4 standard or RCA and so on
*why 4.4mm is important ?*. It can fit (large wires) up to 18-20 Awg wire sizes. Everything within the chassis (internal pcb or wirings) on any desktop equipments ranging from 20-22AWg, and in the while the pcb tracings and wirings on portable is 26-30AWG. Especially A&K, they use the 2.5mm balanced because it can fit 26awg, but their internal pcb traces are around 30AWG sizes (even ribbon cables). So they adopted it. Ibasso dx200 amp modules are about 28Awg or so. The largest I have seen on Portable device is Sony Walkman 1A/Z, it is a whooping 20-23AWG from pcb tracing into wires, toward 4.4mm.
In a senses, 4.4mm is satisfying for even desktop usages. It can also fit on portable players, even smartphones is possible as the 5th ring can be used for microphone and the rest can be connected into balanced audio out. The 4.4mm is universally genius and can be applied onto everything.
There won’t be anything newer than this. Anything larger or bigger need, there is Mini XLR. Then standard XLR, then Speakon....etc.....
In conclusion, 4.4mm is here to stay worldwide and will be seen more often just like RCA, XLR...etc....
Dx200+amp4s is really something else. After burn-in in, the sounds became even more smooth and musical. My HD800S synergize well with it (yes, soundstage, and yes bass.) It is the best amp module I have had by far from (1-3-4 and 4S)
