Awesome to see people rocking the iPod Classic! Absolutely love mine! :)

Coming from a fellow Metalhead!   One thing I have learnt from my many headphones and setups, is too much bass ruins the track (imo)!    For me, out of those two, I would go for the Momentum 2.0 or the V-Moda XS like mentioned above.   The V-Moda M-100 are just too bassy for me, and in my...

Out of that list, I'd go for the Fiio X7.   No need for the DP-X1 unless you really need the dual DAC & AMP chips plus the balanced output.   I would also look at Pioneer XDP-100R, basically the little brother to the DP-X1.

Personally for me, Hi-Res is something to get somewhat excited about but not something to buy new gear for.   In all honesty, I would personally say that you demo a few Digital Audio Players like Fiio & Sony with Hi-Res music files with CD FLAC & MP3 320Kbps versions of the same files and see...

Well CIEM's are custom molded to the shape of your outer ear and ear canal, that is why they do not require the use of ear tips as the mold of CIEM will fit deep into your ear canal.   Short answer is, no. You won't be able to fit some kind of ear tip to the end of the CIEM for someone else to...

I tried using the X-Dap Link software but even once I managed to get it going, it was simply a lot easier to drag & drop via Windows Explorer.    I would suggest just sticking with that and leave the software.

I would probably suggest going onto the Manufacturer's website and downloading the latest drivers for the dongle, I wouldn't use the CD as most likely the drivers that are on the CD are out of date to what is online.

No worries, glad we could help!   Good luck :)

Don't forget that if we listen to something for long enough we tend to think that it sounds best and it isn't until we listen to something that is better, that we realise how better sound can be.   So yeah I would say give it some time for you to get used to the sound.   Honestly if you have...

Sometimes old amps have the ability to add remote IR units to them via a port on the back but unfortunately your receiver does not have this ability and most likely, as you've said, due to its age.   My only solution is do get a new receiver with an IR blaster built into the unit and an...

Firstly, welcome! :)   Your theory and idea of what you want to do is correct, a Multi Input DAC will do exactly what you want it to do. You will be able to input multiple sources into the DAC, connect the DAC to a single set of speakers/headphones and then be able to switch between sources on...

No problem :)   Glad I could help.

As long as the dongle has Bluetooth 4.0 or higher than you should be fine.    I would simply go for the one with the best reviews + highest bluetooth standard + Perhaps have AptX onboard as well.

Personally, I don't really believe a "burn-in" effects the sound signature or quality.   For me I found the Fidue A83 highs to be harsh initially and to this day they are still as harsh as they were when I first heard them but I have personally become use to the harsh/sparkly highs and like it...

This has been fixed by firmware update.
