    DIY Headphones - I need your opinion and advice on drivers.

I have an issue with drivers, as I will not use donor drivers from Superlux headphones anymore, instead I will buy new drivers because I want something a bit better.   Obviously, first choice is aliexpress, as...

    Asus Xonar D1 is very impressive

    I got this card recently for my media PC to use it for the optical output, but damn, the thing is very good. I mean, I've got plenty of other much more expensive DAC's, and I've used the Essence ST in my main PC for a long time, but to be honest, I think D1 is virtually indistinguishable from it...

    Professional grade headphone amps

    I've been wondering for quite some time now...are any of those professional wide profile (meant for use in studio racks) headphone amps with multiple outputs any good? I see loads of them on pro audio gear web shops...stuff like Behringer, Presonus, Samson, SM Audio, Rolls, Art Headamp, etc. ...

    Measuring headphone output levels and the topic of channel imbalance

    For reasons explained in this post, I'd like to ask you to take a listen to this 30 second video and tell me where exactly do you hear tones from left, right and center channel. https://www.youtube.com/watch?v=_Rlnp7wRnKs   Is any of the tones obviously louder than others, is the left or...

    Beyerdynamic T1 - disappointing performance in my setup

    I've recently bought the T1's and I'm currently using them with a Nuforce HDP dac/amp.  I know this is not a perfect combo, but the DAC section seems pretty decent with the AKG K701, and there's enough power for T1 to get them way too loud nowhere near 100% on the volume knob.  But, the thing...

    Which one is "it"? T90, D600 or M4U2

    So, quite a weird list I have here with three completely different headphones.   The thing is...I'm looking for a upper mid - high end can, so not quite HD800 / T1 / LCD2 level, but above DT880 / HD600-650 / K701.     What I don't care about AT ALL is sound neutrality. I don't care if...

    Onkyo A-5VL - A game changer

    I want to spend a few words about the device I bought today after thorough testing (3 hours in a silent room in the shop) against three obvious DAC/headamp combos between 500 and 700$. First let me say that before I entered the store, I didn't even know this device existed.  I went in to return...

    Need help with chosing an integrated amp

    So, what I'm looking for is an integrated amplifier for speakers, which would run some small bookshelf speakers, and it also needs to have a great headphone output.  Its for a setup that would be used 50% for speakers, 50% for headphone listening.   I used my HD650's today on a NAD C326 (the...

    How to make sure if the DAC is working?

    So, I have a weird question.  How to make sure that my standalone DAC is doing the sound processing, and not just sending the signal that it receives from the PC to my amplifier unchanged?   My chain looks like this:    PC -----coaxial--->  Musical Fidelity M1DAC    -----rca-----> amp  ...

    Samsung Galaxy S vs. Musical Fidelity M1DAC - unbelievable, does my DAC work?

    Let me start off by saying that this comparison was made totally by accident, it was not meant in the first place to compare the DAC's in my phone and in my 800$ standalone DAC praised by many as one of the best best on the market, but what I found after just being curious about how the phone...

    Matrix M-stage vs Bellario HA540

    So...it's tube vs SS.   What would you choose for use with several different headphones of different sound signatures and impedances, fed by Musical Fidelity M1DAC?   It's a must for me to be able to adjust the sound signature of the amp, so that's why I want to be able to change either...

    Asus Essence One vs. Musical Fidelity M1-DAC+ AudioGD C-2.2

    So, I'm upgrading from my current Asus Xonar STX + Little Dot MkV setup to something more high end.   Which DAC or DAC/amp combo up to about 600-700 dollars would you recommend? I can get a used M1-DAC for 300 dollars, which is why its included in this comparison, otherwise it would be too...
