Yes, better sound quality. Lower end audio-gd, like nfb12 or 11, should be avoided with hd800.

I used to have audio-gd nfb12 (supposed to be slightly warmer version to nfb11), and there are other products better it in similar price range for hd800. Schiit Vali better it for amp only (combine with modi multibit maybe, for dac/amp). Or for single dac/amp, geek out v2a or v2+ better it as well

Maybe also try Maxx134 Version 2.5 MODs at the other site, which IMO further improve he1k further. It offer slightly better treble, less laid back, better impact and similar staging. When I compared to he1k v2 at the store, I did prefer modded he1k v1, since v2 staging was still slightly more...

Maybe because he auditioned a cold demo unit? I can't listened to my almost a year yggy from cold. Sound hard and metallic on its timbre. Usually need about 3-4 days after if my house had a power outage (which happened 4 weeks ago) But maybe it's preferance as well. Metrum Pavane is a great dac.

Yes, I had the SD mod installed already for about two months. It was quite easy to install and take them off. I had tried the original mod which based on shure tips, but didn't like it unfortunately. And yes, you may try mine. Maybe we could follow this on pm

I bought my hd800 about 3-4 years ago, after listening them with a ZD. A ZD is truly an amazing amp with hd800! I think you should consider to investigate a SuperDupont mod by sorrodje to further improve its performance. It was truly an awesome mod!   And if you happen to be in SouthEast...

Interestingly, I currently enjoy the tubes combo which previously I liked with he1000, U52- TJ Full Music/SE. Shuguang Natural C-T still quite good, but it's a bit too rich with SD Mod, while Sophia Princess is a bit too wet. It will be interesting to try KR 2a3. Hopefully, I can find a pair...

It's been almost 2 months since I run my hd800 with the new mod SuperDupont, invented by sorrodje. I like it a lot. Previously, I had my hd800 modded using rug liners only. Now, SD mod and dust cover only. This mod brought a new height to hd800-Stratus pairing! Highly recommended! It made me...

On additional note, the hum from input tube tend to follow the volume pot. IME, if the input tube start to go wrong, the noise will increase and decrease when volume pot turned up and down.    While if 2a3 tube which go bad, they do tend to follow the swap between left and right, and seem to...

Yup, and some even prefer hd800 series to all those phones in the synergized setup :-)

In my setup, the warmest input tube was 6bq7 RCA. And my favorite was cheap Gold 6N1P-VI. I bought 4pcs for $18 shipped to AUS last year. They seem more balance than 6n1p-ev (being bright) and 6bq7. I use it for both he1k and hd800.

I used to have Sonicweld Diverter, using iUSB and LPS from my custom music server with LPS. When I had my previous dac, audio-gd ref7, I prefer those setup to everything from JKspdif mk3, Ciunas and AP with battery and/or with LPS. During break-in of yggy, still prefer Sonicweld Diverter setup...

A few weeks ago, I managed to go back to my local shop auditioning new headphone (bringing my modded hd800). It's quite interesting when I managed to listen to their he1k, I also spotted this slightly rough treble compare to hd800. While at home, I didn't notice this issue with my he1k (to my...

Yeah, same here with globe TJ Full Music 2a3/SE and U52 rectifier combo. I hardly listened to hd800 currently. Listened to fresh lcd4 at store using wa5, but still prefer he1k. Maybe it need more burn-in
