What's in the box!

If we’re talking about isolation from sound escaping from open-back headphones, I’d love to see the physics regarding how much that sound energy is cabable of moving a mass in the range of a dac or amplifier.

I mean, it’s the energy required to move a headphone diaphram compared to the mass of a dac or amplifier.

These are nice footers. Have several sets….Bronze and Graphite.

I don’t think that’s it, though. Electronics have their own vibrations, not to mention that I’m in a building in NYC with subways and cars driving by. Isolating each device from the others around it and the world around it is the main goal.

Glad to join the club! Indigo, and Graphite on back order.

Nope. That is negligible and likely unmeasurable.

My first exposure to audio dampening systems happened when visiting someone who was copying LP records to cassettes. I walked across the hardwood floor and was scolded: “The record will jump and make a ‘thump’ on the tape with every footstep.” So, I walked softly. Then, after a while I forgot and clomped my way across the room again. And I got scolded again…and just left the room because it was hard to be so still…

With my own tube amps, I sometimes hear tings and rings when I adjust the volume or touch the amp. It only takes a light finger tap. The Utopia is ridiculously sensitive to vibration, but the HD 800 S is also very sensitive. Those tings are masked when music is playing, but they surely have some impact. YMMV as to whether you notice or care.

Also, bookshelf speakers often generate muddy garbage unless isolated from a bookshelf or furniture. They work best on dedicated stands. I’m currently using foam pads because mine are on shelves, but until the pads arrived I used recycled padded mailing envelopes (which absolutely worked but looked awful).

Yeah. HVAC, fans, clothes washers and dryers, dishwashers, water running in pipes, public fountains, vehicles rumbling, airplanes and helicopters, sirens, trucks, honking, people playing bass-oriented music. Some urban locations are swamped by noise pollution.

Fair enough, not dealing with noise from headphones.

Thanks for the reply… they look great

Great headphones.

Careful with cable changes. Those HD 800 headphone pin ends get stuck, and if you force them out quick or with too much force, you can damage the outer foil adjacent to the cable jack…

Yup heard about that a lot so I put some deoxit gold on em and now they’re pretty easy to pull in and out. Expensive stuff but it works really well.

Sold my Spring Dac and picked up this Ayon Sigma that has a 6h30 tube output stage to it.
Over the years I have always favored tube output stages in Dacs. Always missed my old Lampizator and since then had such sellers regret that I had to pick another tube Dac up. (Specifically with a tube output as some don’t.)

This Dac is very similar to why I loved my lampi as it’s midrange is just so realistic (in the most unsterile way possible).
The vocals have an extra transparent musicality to it over the Spring and provides a much more magical holographic soundstage without giving up too much of the awesome smooth top end clarity I loved the spring for. This Ayon Dac projects/pushes sound out into the soundstage in a way that’s very hard to explain but definitely know it’s from the tubes. It blows up the music in the room where every human grows into a giant. I’ve only gots this from the Ayon and Lampi. I just can’t explain it well in the way I want. It’s like the soundstage is pressurized in a different way.

I’m slowing down considerably in buying gear now as I’m pretty happy with my setup after trying so many amps, headphones and Dacs in the last ten years. Cheers!

Inspired by these posts I tried something I have thought about doing, but just never got around to.

On my desk I have the Euforia and my computer. The 'puter is cooled by an AIO water cooling unit. It has a pump running constantly.

I have bought several input tubes for the Euforia, but have had trouble using some of them because of low level hum. For example the Ken-Rad VT-231 and Shuguang Black Treasure CV-181-Z.

I put Tack-it adhesive under the feet of the Euforia and the Ncase M1 chassis. I can’t think of a more low budget solution, but it worked. Unbelivable! I no longer have any hum from the more sensitive tubes.

So, yeah, isolation made a difference.

Looking good! That bookmark looks like it’s worth half the price of the Chu itself.

Only on day five with the Oor, but I love it so far. I’ve never heard the Ragnarok 2, so it’s hard for me to compare. I’ve also not listened to my Oor without the Hypsos. I was frustrated when doing my research at how few Oor + Hypsos owners had actually tried the Oor without the external PSU. Now I’m guilty of doing the same! But I’ll compare the two soon and let you know.

Ah, so that’s what it is, a bookmark.

I had no idea why they had included a wooden thingy with the Chu :smile:

I don’t think it’s a bookmark. East Asian traditional/religious sites often have memorial areas with little wooden plaques all over. They are prayers or reminders or souvenirs or something I don’t understand. If thin enough it could be a bookmark, but my guess is meant as an advertising hanger or retro poster.
