    New HTC One M8 audio review

    Hello. I have a simple question. What is M8's headphone jack's output impedance? Thanks.

    O2 AMP + ODAC

    I did order from them 3 or 4 times and got taxed only once. The only way to avoid taxes is to get lucky.

    Audeze LCD-2 Impressions Thread

    I remember some guy here listening to he500 on x20 gain and claiming that it's not loud enough. Other time some guy said he sold his hd800 because they were open and he was waking up people next room even when doors were closed. My setup is hd600 (300ohm headphones), odac (set to 50% volume)...

    Millett "Starving Student" hybrid amp

    Looks like I will have to replace them with 63V ones. Anyway, what are C7 and C8 caps used for? I don't have them in my build.

    Millett "Starving Student" hybrid amp

    I wonder one thing. Why C3/C3a/C5/C5a is said to be 63V or even more? There is no more than 12/19VDC on that line. I used 25V capacitors and they're doing the job. Nothing has exploded yet.

    Quote:   I replaced these capacitors with 1000uF, 25V ones. Here is the result.     Thanks. Are there any other recommended modifications that I can make to my student? This is how it looks right now:       And one more thing. I would like to make a linear 48V power...

    O2 AMP + ODAC

    I heard every headphones you named on Odac and o2 and they all do very well. For mainstreamam music i think I will recommend hd650 for you. Lcd2 are also a great choice of you can spend more money. I don't think you will like hd800. About he500... I just don't like these headphones... Remember...

    Millett "Starving Student" hybrid amp

    Can't say much about the pot except that it is 50k stereo. I think that the crosstalk may be caused  by the cable mess in the case.

    Millett "Starving Student" hybrid amp

    I have a question to everyone that built a student. Has anyone tried to measure a crosstalk? I am getting quite bad result:       The lowest my sound card is able to measure is about -75db so I don't think that it's a problem in here.

    O2 AMP + ODAC

    I had a chance to listen to t1 (600ohm) from my Odac + o2. As far as I remember with 2.5x gain and volume control at 12 they were quite loud. I was listening to them in loud environment so for everyday use I would probably keep to 1x.

    London Head-Fi Meet April 2013

    There is not much to say. Very well organised meeting, nice people and great hardware.   I took few photos to share with you but they ended up terrible so I will upload the only one that is decent.

    I still would like to know if it's ok to bring a camera with me. I would like to know it as I need to know what to pack tonight.

    O2 AMP + ODAC

    Thanks. I will have a read later.   I'm not a big fan or eq nor heavy bass. I think I will just try to do some proper blind test between 80% and 100%. Hope I was wrong.

    O2 AMP + ODAC

    I always had my ODAC set to 24/44.1KHz. I feel like any volume level below 100% has a bit less punchy bass. It might be just a placebo effect but my friend felt the same.

    Few questions about CMOY

    So my cmoy can work on 12v without a problem? Do I need to disconnect batteries when connecting power supply?

    Few questions about CMOY

    Sorry, I already changed R3 to 7.5K. I have another question. I don't have any 9-10V DC power supply and I don't want to spend money on it. I happen to have 12DC 500mA power supply. I guess I need to put some resistor in series to drop it to about 9,5V. My question is what resistor do I need?

    Few questions about CMOY

    Just replaced with 7.5K resistor and it's great. I also noticed that output impedance dropped from 0.51Ω to 0.13Ω.   If I will ever have more questions about my CMOY I will post in this thread.

    Few questions about CMOY

    Hello. I just finished my first CMOY using this guide. The only modification that I made was that I used 2 batteries and LME49720HA opamp.   Q1. What will happen when batteries will run low? Would the amp just stop playing? Q2. The amp is a bit too loud for my liking. How can I lower the...

    Maybe you can get these to, or something similar:   Link 1 Link 2   I don't think you will find short 3.5mm to 3.5mm cable.
