Audio-Technica Ath-cks5tw in this case. 10mm DD, amplification, BT receiver, microphone, 3.7v li-ion battery. What kind of driver and electronics do you use to get 15hrs at 10 grams/each? 🤔

Here is my contribution. A Sony Ericsson W995 from 2009. Around 20 hrs of music listening. Decent sound quality. Phone included 🙂 Design++ Good music player software for it's time Drawbacks Only support 16gb memory cards Uses the now rare Sony Memorystick M2 micro

Hi, it would be nice to view not only the high-end stuff, but also the vintage source gear that are still in use, while commuting, excercising or doing something else.. It's a good reminder where we all come from and how far development has moved since. Portable MP3 Roots might be a fitting theme..

Well, at least Harman seems to be involved in the audio bits. Other than that, it has an e-ink display, 1900mah battery, plays FLAC and has a price worthy an Apple product. Strange times. https://mudita.com/products/pure/specs/

Very good and precise clarification. Thank you!

Yep, I agree with all of the above. As I understand, Tidal is the only streaming service that actually uses LUFS for loudness normalisation. Spotify uses ReplayGain, Apple some proprietary software and the rest a mystery. All streaming services seems to be pretty consistent, with tidal at the...

Interesting stuff. With veteran sound engineer Alan Silverman. Video starts around 3min 50s. Future of mastering

Tomorrow I'm borrowing a Aune X1s + xp1. Interesting to try with the Quad. Will report back.

Yep. Like the Sony WM1Z. Or the A&R Ultima SP1000. But atm I'm quite happy with my A&K jr. Except the laggy UI. But.. thats manageable..

Thats interesting! I have not that many hours with them yet, but I noticed that the difference between the 2 supplied pairs are quite noticable. But I think it would be an easy job to 3d print the plastic part that holds the ear pads to the frame and attach anything you like.

...but my g** they reveal bad recordings and faults :scream:

Fully enjoying Dvorak and Mahler on dsd recordings through the Quad Era-1 :k701smile: Really something else compared to the B&W.. Got two sets of ear pads. Think I prefer the leather ones a bit more, at least for the classical music. Now off to some Genesis, Gentle Giant, Yes and Rush! :L3000:

How about the sensitivity of the Quads? Are they fairly easy to drive? A friend is making a buzz about Tidal Masters, and I'm going to try it out for a month or two. Is the Audioquest Black with 1.2vrms output good enough to drive the Quads from my phone?

I have the P5. Enjoyable in their own way, but got the Quads instead of the P9. Although very Good (P9) I want to move away from b&ws sound signature to something else.

So... After much research and thought I ordered the Quad Era-1 today. Have a Astell&Kern Dap I will pair them with. Will probably bild a "Whammy" headamp from PassLabs later this summer. My well used B&W headphones will be demoted to commuting gear.

Hi, I have had the AKG 172HD for 10y or so, but they have not been used for a good while because of two cable breaks, one is close to the cans (8-9 inches) the other one is further down. Going to replace the cable, thinking of cutting it and solder a 3.5mm (1/8") female connector and use a...

I dug up some interesting facts.. Theoretical dynamic range 16-bit = 96 dB 24-bit = 144 dB 32-bit = 192 dB 64-bit = 384 dB More interesting facts: Human voice dynamic range 96 db Human hearing pain threshold sound level 120 db Best microphones dynamic range 170 db 194 db equals to 1...

No, UltraHD seems to refer to the 32 bit depth. Supposedly the highest depth resolution available, advantages claimed to be highest possible dynamic range and lowest possible noisefloor. Conversion to 24 or 16 bit ofc needed for disc output, never heard of a commercial available DAC that reads...

Found this great site.. It explains the differences between Mastering systems and audio discs.. http://www.firstimpressionmusic.com/Articles.asp?ID=134

Hi all, Actually I didn't know where to start this thread, but I guess it's closest relationship is in the source cathegory.. Anyway, the other day I found a music disc with a mysterious "Ultra HD" printed on it. After some googeling I found this site, with interesting reading...

Thank you!   I dont think the K172 necessarily has a better separation or a higher level of details than K242, its just different. Since the K172 is closed, it gives you a more direct, compact and forward sound, while the K242 is more relaxed and open. If the K172 takes you very close to the...

pearlfact: The 242s are very good headphones, but they are rather big and are hungry for power. Bass didnt come out great from my Iphone on higher listening volumes.   danneq:  Interesting, didnt notice that. Im sure they will improve a lot by removing the foam. Main reason why I did not go...

sumathias: Yes; I have listened to the K701, but not at this occasion. From what I remember sound is similar to the semiopen K142 and K242. From the sub 100$ headphones there is a huge difference up to the K701 of course, but im very impressed of the the sound you get from AKDs HD series, well...
