Thanks for your kind reply.
I'm now considering asking them to do 4 pin instead.
As one who has used the 4 pin connector on my JH13, I don’t recommend it. The 7 pin is a lot better, solid connector that doesn’t come loose. It’s also strictly sweat proof.
Not sure about sound upgrade, maybe but the 7 pin connector is really a lot better.
My personal advise is to get the 7 pin, wait for upgrade cables later. Your mileage on cables isn’t as big as a good DAP, DAC or amp. Since you are already using the flagship AK Sp2000, you already have quite a good setup.
If I remember correctly, the good cable upgrade would be the Effect Audio Leonidas II Octa but that’s would set you back more than $1 grand I think.
My priority of investment would always be:
1. The headphone / earphone
2. Amp or solid DAC amp or DAP
3. DAC
4. Cables
My ideal setup would be transporter (iPhone) —> Hugo 2 —> headphone or Hugo 2 —> dedicated amp —> headphones.
Cables might be last on my list
But that’s just me and my 2 cents worth.
