You are lucky, or better at handling the X1. Mine is literally falling apart, the 2.5 socket Copper ring decided to fall off, it actually broke off its plastic body.
I'm super careful with the Onkyo X1, I use a 2.5mm dangle pretty much permanently plugged in. And I connect my headphones to this dangle, so not to unplug, and plug in another plug. This, of course, is insane. A head phone socket of any smartphone today can be plugged in, or unplugged without having to worry.
I'm going to say it now, as far as hardware, the X1 is an absolute joke of a device. A complete disaster, given that there's ZERO customer service on Onkyo's part. If I was in Japan, Onkyo would have replaced my X1 three times by now. Apparenty Onkyo replaces their defective units, no questions asked. If you bought from Japanese dealer. I didn't.
They are all defective. If yours still in tact, give it some time!
But I'm not Japanese. I'm stuck with their defective product. No replacement, no warranty socket replacement. In fact no reply from Onkyo Japan lol. This is unheard of.
So I kept s 2.5mm dangle plugged in permanently
But since last week, after rewiring every headphone cable to TRRS 2.5mm plug, I started to unplug and plug in different headsets, all of them with 2.5mm balanced plug.
Guess what, yesterday the Copper ring that covers Onkyo's output socket just dislogged. It was dark in my room, and in the morning I discovered there's an input socket staring at me, but Copper ring is gone lol.
I found it later that night, it was resting peacefully on my bed sheet.
Here it is, the little "Copper" ring, that really turned out to be piece of thin, brittle plastic, and it broke off. Not by abuse on my part, plugging and unplugging headphone plug is what this socket should be able to take 10 years, my 2003 iPod 10Gb FireWire connector still in tact.
This is what Onkyo X1 Copper ring at 2.5 Out looks like. I'm just gonna glue it back in place with Crazy Glue. With any other manufacturer I'd ask for repairs, or replacement, with Onkyo this is tricky, their corporate policy is ignore email for customer service.
Onkyo, hire me as consultsnt when you're designing your next device. Free! No cost to you! I will simply list you the basics of what a Walkman requires as a MUST. Being 25 year veteran of pocket devices, I know what fails, what attention needs to be paid to! (For example, physical lock to disable all physical controls if the player, something your X1 doesn't have)
Howdy, what kills me, Onkyo DP X1 beats both iBasso 200, and Fiio X7 II, in my opinion.
As long as Onkyo works. Unfortunately not very long, 2.5mm fails first, 3.5 quickly follows.
Onkyo X1 is a strange device. It's top of the game, best DAP I've auditioned, it beats DAPs priced $3000, grossly, obsinely, INSULTINGLY overpriced products.
Machined Aluminium DAPs, costing several thousand $ are a joke. It's time to put cards on the table, and stop deceiving less informed customers! A good, well made, all metal DAP should not cost more than $500 USD.
There is no reason for a DAP to cost more, unless machined from previous metal.
Onkyo, hire 2 or 3 people, and call them Customer Service. Novel concept for you, sure, but try it! Works well in long term!
