    Sennheiser HD 620S Headphone Review

    Having a lot of discomfort with the 620S, I realized that the internal height 70mm and width 48mm is too much for my smaller head and the pad ends up touching my jaw, causing pain and temporary tinnitus. I tried bending the metal extenders a bit outwards to reduce the clamping force, It...

    Can headphones played at normal volume cause hearing damage?

    I used to get tinnitus when using closed-back headphones. IEM is even worse. "Sound waves have nowhere to go but bounce around inside your ear. This creates a lot of pressure on your cilia and eardrums and wears them out very fast." (source here).

    Help me pick a pair of headphones and a DAC-AMP for it

    A bit late, but If you don't need a closed-back headphone to higher isolation, a (original) Koss PortaPro is what you are/were looking for. I'm also very sensitive to many headphone's factors and I can listen this PortaPro for many hours without listening fatigue. If you need a closed-back...

    Shure SRH440A and SRH840A

    I’m thinking about It lately. How can I say If a headphone has or not these holes? For example, HD 620s or Fiio FT1? I tried in the past some headphones that I couldn’t keep in the ears for too long: Sony MDR-1A and Sennheiser HD-25. They were painful to me. Maybe something to do with these holes.

    Shure SRH440A and SRH840A

    Thank you all. Actually, I don’t really need a noise cancelling, wired with good passive isolation is fine to me. But Creative was really disappointing in isolation. My reference is a cheaper Anker that passive isolation (without ANC On) was good as expected for a closed-back. DT770 with passive...

    Shure SRH440A and SRH840A

    I have a question. I saw on diyaudioheaven that the isolation of the SRH-840 is "pretty decent", while the SRH-840A is just "decent" (same for the Creative Aurvana Live! SE). And in the Summary It says more "The isolation is not great for a closed headphone, but there is some attenuation of...

    Audiophile music player for Windows/Mac and your opinion...

    Not an issue, a characteristic. Whether it's important or not for some is something personal.

    Audiophile music player for Windows/Mac and your opinion...

    XMPlay with xmp-wasapi.dll, without any DSP. Kind of ugly at first, but with WMP11Skin It adopts a very minimalist look that is in tune with its extremely low resource usage.

    Can different CD *transports* sound different - when fed into the same DAC?

    I don´t have too, but I read in the test done by amirm of the Cayin Mini-CD MKII CD transport: "it is odd harmonics which tells me a bit is being toggled. From this, I am pretty sure the Cayin's digital output is NOT bit exact!!! It is literally producing different digital samples" "And if my...

    Is there any objective way to determine whether the Apple dongle is capable of powering a headphone to 100% capability?

    I mean, it's certainly loud, but it lacks punch, the music is a bit anemic. Couldn't it be the low mW supplied? It's the USA model, used on an iphone, apple music, any music.

    Is there any objective way to determine whether the Apple dongle is capable of powering a headphone to 100% capability?

    My Koss Portapro was very quiet with this apple dongle. I thought about getting a lightweight dongle amplifier to use with it, but I couldn't find one.

    Rega Planar 1 vs Audio Technica LPW30. Integrated amp vs amp and preamp?

    The HiViNyws channel made some videos that proved how a Rega P1 is very capable, even against a more expensive Pro-Jects. The problem is that they don´t have anti-skating adjustment tu use with other cartridges, but there´s a tweak showed in this video. I had an Audio Technica with some of these...

    Lossless stream with an iPhone (apple music)?

    Yes, tested and a cheap good solution. Do that, a new DAC will be a good investment at this point. You need a program like UAPP in Android to play bit-perfect audio, and It only works with Qobuz and Tidal right now.

    Serious Question: How can DAC's have a SOUND SIGNATURE if they measure as transparent? Are that many confused?

    A lot of music was mastered before the existence of a DAC. Mastered not only with the technology of the time, but also assuming the popular equipments of that time would be used to reproduce it.

    Serious Question: How can DAC's have a SOUND SIGNATURE if they measure as transparent? Are that many confused?

    I have a hypothesis that tries to reconcile objectivism with subjectivism, and I haven't seen anyone delve into It. The songs are mastered in studios with the equipment available at the time in mind. Two DACs with the same SINAD/measurements will sound identical. Some music (some 80's heavy...

    Topping L50 Review (Headphone Amp)

    Crystal clear. Back to my original question, this leap from 250mW/32Ω to the 2.8W/32Ω of the L50 is the same phenomenon as increasing the gain from low gain to medium gain? Or are they different concepts? As I experienced that my headphones didn’t work well with higher gain in CD6006, I wanna...

    Topping L50 Review (Headphone Amp)

    Topping L50 Review (Headphone Amp)

    Just to make sure, I also have a Marantz CD6006 CD player that has a headphone output with gains: Low, Medium and High. The manual doesn't say anything about this, only that it should be adjusted according to the impedance. The sound is bad when set to Medium/High. More specifically, is this...

    Topping L50 Review (Headphone Amp)

    I'm considering this headamp and I have a question about input impedance, wattage and headphone matching. I currently use a V-CAN II which has the following in specifications: input 25KΩ and 250mW/32Ω. Headphone is a Grado SR225i (32Ω 98dB). 1) What would that 25KΩ input be? I saw that Schiit...
