Added the Hifiman Serenade.

I had a chance to audition it on multiple occasions and enjoyed it, as well. I think my personal tastes lean towards the clean and clinical. I've tried to enjoy more "coloured" amps but must admit that I prefer analytical amps, overall. If I want to change the sound, I rather EQ or just swap out...

I've had pretty decent results with the Stealth and the ifi Gryphon. Xbass helps a lot with this combo and for a transportable setup it works great in a library or hotel room.

I've owned the Stealth for a couple of months and can't get over how amazingly "neutral" it sounds to my ears. Don't get me wrong, I love musical headphones and enjoy my other cans, which include a modified HD580 that I've owned for over two decades now, as well as the VCs and recently obtained...

Great to hear that you're enjoying them!

Lately, it's been the Blessing 3 and ifi Go Blu. In combination with double-flanged tips, I find this fixes the bass issues with the Blessing 3. It easily beats multi-thousand-dollar IEMs with this combo IMHO.

Let us know how you like them. I'm curious about a pair for myself, too.

Haven't heard them myself, but I read that the Drop + Ultrasone Signature X is made for bassheads. It also fits your budget with some change left over.

lol... Yeah it's a bit of steel... Not that I know what to do with them all. Although I do use almost all of them... To cut open knife delivery boxes 😆

Got the folders together for a family photo.

I don't own one but would love to audition with you. DM when you are in town!

The devices you listed in the OP should have switching power supplies. Might want to check as you may not need a stepdown adapter, just a regular plug converter. Let me know if you're up for a beer when you're in SG. Happy to share my listening station!

Anyone know the dimensions of the Silver fox? Thanks!

So tempting...

Interested in hearing your impressions. Almost pulled the trigger on the Mini C until I learned that the O2 was on-ear. Was looking for a PX100 replacement and I'm not disappointed. I've been listening to more music on the O2 and it does almost everything better than the PX100, except for mids...

Just got my O2 a few days ago and it's been really great so far. Using it mostly for gaming but listening to a bit of music, too. For an on-ear it's pretty comfortable as it's cool on the head and light on the clamping force. Build-wise it's decent for 3D printing, but the headband and gimbal...

Rupert Neve Fidelice Precision DAC added.

That I'm not sure of as every setup is different, with different variables.

You can use a USB switch like @chezzer suggested, or go full on KVM switch.

From the manual: This seems like an odd recommendation. Is this a typo or mistranslation? Or do they mean that one may use multiple headphones simultaneously?

Added and thanks!

I have no doubt that it should be on the list. Excited to read some listening impressions and eventually trying one out for myself.

Nice suggestion but it doesn't have analog inputs, which means it can't be used as a stand-alone amp, missing one of the criteria to be on the list. Looks like a pretty versatile unit tho. Maybe we need another list for end-game, all-in-one units?
