DACs used were Schiit Wyrd + Gungnir gen5 USB, Schiit Modi Multibit, Schiit Fulla2, and Mojo. Bluetooth sounds bad but if you can use network receiver like raspberry pi with Volumio, you can stream from SR15 via wifi.

USB compatibility of SR15 using audioquest Dragontail OTG adapter, both in and out is very bad in my experience. I compared it to SA700, AP80Pro, iPhone. It works in some DACs, but some DAC recognizes but doesn’t sound, some DAC works if you half pull out the connector. And what is really bad...

That should be just same as the rated spec. You can calculate to watts if necessary.

Yggdrasil OG is fully Multibit DAC but not 100% R2R. Go and see datasheet of AD5791. It is hybrid of R2R (14bits) and string DAC (6bits), which are both Multibit but having different architecture. String DAC is complicated but better than R2R? LiM and MiL are full R2R if my understanding is correct.

Burn-in clears it a little bit, but in my opinion JJ has really colored tuby sound, it might be good or bad depending on your preference and system synergy though. Tung-Sol sounds clear and I love them.

Thanks. I always thought that metal sliders? were much more stretched out on HD580 compared to HD650 (very old one). But thinking that due to larger radius (smaller bent, probably I bent looser?) on HD580 headband. And your phots looks just like mine and surprised to know that the length seems...

final is saying that black and clear sounds different due to some material for coloring added in black ones. Probably you can find it somewhere on the web. I don’t remember what they said precisely about the sound but in my vague memory it was bass volume due to different contact to your ear canal.

I don't have Stealth, but have Ether2. Many people says it lacks dynamics and compressed, but to me it is not. But, yes, I sometimes feels Ether2 (original pad) too modest, or slightly lacking of presence/treble region, or you can say it bit boring, and I think that is what many people say...

Yeah, metal is the most similar genre to modern/contemporary classical music. I can't bear listening to some types of classical rock, but metal (especially progressive metal?) feels just really familiar to me who grown up with classical music including playing flute in amateur orchestra. Heavy...

From the spec sheet, R5 Sabre outputs 1040mW@16ohms, and around 30mW for SR15 in 16ohms, so, power wise, quite different in 16ohms. Could be more different or less but still must be big difference in 10ohms. However, both shall play LOUD, and sound wise, you have to audition to know if it sounds...

No, I think it is wrong. Your calculation is just theoretical output calculation for 2V and 4V to 32ohms, but actual current hits limit in low ohms and voltage gets down. V=IR I = V/R = 2.0/32 = 0.0625A (or 62.5mA) W =IV = I*I*R = 0.0625 * 0.0625 * 32 = 0.125W = 125mW (your calculation) This is...

That is for infinite impedance. It significantly drops in low ohms such as 16 ohms.

Every digital transport makes difference in sound. It depends on gear. In my opinion, digital out of AP80 Pro Copper using audioquest Dragontail is not bad but my 8 years old MacBook Pro retina sounds way better to me as a digital transport. A&K SA700 sounds better than AP80ProCP as well both...

I have FI-BA-SS and have auditioned A8000 at the final HQ. A8000 is ultimate clarity/transparency and positioning. Just as what final say “Transparent sound”. To my surprise, FI-BA-SS felt dull compared to A8000.

Yes I agree. SE sound more stronger center to me, while BAL better separation and holographic sound, and way better defined bass. If you prefer more in-your-face vocal presentation, SE might be better. I prefer the better separation and controlled bass so only using XLR if possible. Only rough...

No, in most case no. There could be power issue, but besides the power, oppo HA-2 is one of the RARE DAC that could be connected from iPhone with standard charging cable. oppo HA-2 has USB A receptacles (big flat rectangular one on old PCs) , but most DAC has USB B receptacles (Full size or...

I agree. I often wanted slight more treble on original pads and finally got the perforated pads after hearing the perforated pads got standard pads. The perforated pads sounds more like ordinary headphones to me in both good and bad meaning. And I don't remember if it was a big cup feeling or...

Genuine leather case from A&K is good as well. I think it is only sold in Japan, but exactly the same shape as artificial leather version, but made of real leather to match Japanese original color version SR15. There are white and military green, but white one has bright blue stitch and maybe...

Okay, it past 150 hours. Tonality wise, it passed acceptable level to me, but I think it is still changing and could be better. Bass had tightened up significantly (still expect to be better though), and vocal/melody-instrument became alive (expect be a bit better though), congestion got mostly...

Looks like this is a written review by same gal in e-earphone Nagoya. it just showed now in my iPad in chrome suggestion. (in Japanese. You can use google translation?) https://e-earphone.blog/?p=1362265

Thanks for sharing the video. It is a live streaming video of e-earphone Nagoya. She is saying that A3000 sounds like upgraded version of E1000. (Rather than the sound signature of E3000) Also saying that A4000 has sound dispersing outwards while A3000 has sound coming to you like jellyfish...

Burning in P2 since last Saturday. Yeah, first impression was terrible. Muddy overwhelming bass, lifeless submerged vocal/melody, and congested sound. Now nearly 100 hours and getting significantly better, but still not good. Just getting near to "acceptable" level to me. Well, it is still...

Output of AK players significantly drops in low impedance. My SA700 which has same output power as SR25 doesn’t drive ETHER2 well even in balanced output. And Aeon has even lower impedance which means more current required. Way cheaper Hidizs AP80 pro Copper in balanced output drives ETHER2 way...

Hi, Jason, I know I have already reported Amazon Music HD always show LED in blue what ever bit rate you play, but Apple Music always shows LED in red as it should. JFYI.

Thank you for the clarification.
