I am a user of K01 too. But I don't think the K01 XLR is a must.
I have the K01 connect both XLR and RCA, XLR with +6DB connected on headphone amp and RCA for speaker amp. The XLR pair are stealth sakra v10. And RCA pair...
Of cos no water on it. salt or un salt.
I am even run it near by my bed and have air cond on.
but it is true that Hong Kong have a wet weather, but not in my bed room. And bhse is the only amp I have fail in this 2 years.
