In regards to my question, it seems like you're saying that while a high damping factor is important, it does not impact sound quality as much as voltage. Due to its high output impedance, the Beyerdynamic A1 is not a good value headphone amplifier because of its limited usage with high...

So I read on NwAvGuy's blog: This statement seems to imply that lower output impedance on amps is better.   One of my acquaintances told me that a high impedance headphone must be paired with a high output impedance headphone amplifier, and he pointed to the Beyerdynamic T1 and A1 as an...

I like all kinds of music including bass-heavy music. (I listen to Rock, Classical, Jazz, Electronic, Hip-Hop, etc.) The reason I would prefer a description relating the JH-13 and JH-16 to other headphones is that many people have different bass preferences. For example, some people think the...

I am also having a bit of trouble deciding between the JH16 and JH13. How would you describe the sounds of both IEMs relative to other headphones?   Headphones I listened to include the Beyerdynamic DT 880, Sennheiser HD380, Ultimate Ears Triple.Fi IEM, and the Audio-Technica ATH-IM04 IEM.

I would also like to know the difference in quality between a dedicated DAC (like the Schiit Modi) versus an audio interface (like the Steinberg UR22). I currently own the UR22 and it is able to drive my DT880 250ohm headphones, but I am wondering if an additional investment in the Modi/Magni...

yacobx, is there a noticeable increase in sound quality when you plugged in your DT880s into the Schiit vs the Focusrite? I currently own a Steinberg UR22 audio interface and it can drive my 250 ohm DT880s just fine, but I am wondering if investing in the Schiit Modi/Magni is worth it for the...
