    Being a good father thread

    I really apologize for such the unconventional thread. However, I really respect the people that frequent head-fi, and I couldn't think of a better group of people to ask. I am very worried about being a good father. My wife and I were just married about a month ago and are looking to start...

    A note to newbies

    From a recent newbie to all of the current newbies who are feeling out the whole hi-fi headphone situation, I just want to give my unqualified advice.  I felt I was missing out on "hearing" the best I could, so I embarked on my journey of testing out hi-fi audio equipment.    I got a Zero...

    Is your computer secure against hackers/snoopers/thieves?

      Hi everyone.  I finally got around to doing an overhaul of my personal computer security policies.  Considering that I use my computer as a filing cabinet for all of my important and personal documents as well as doing my banking and many transactions over the computer, it is imperative that...

    Windows Media changes my music when it plays it

    I have a large archive of lossless music on my computer which I very much want to keep in original condition. Therefore I have taken several precautions, 1.) I back up my all my files locally and to an offsite drive 2.) I keep SFV (Simple File Verification) files for my archives to...

    I am giving up on hi-fi

    I am giving up on hi-fi. I just don't think I have the ears for it. My foray into audiophilia started when I realized I could not hear the difference between relatively low bit rate mp3 and lossless. I figured I needed better equiptment. So I got better IEMs, Sleek SA6, which I love and can...

    Anyone listen to podcasts?

    Anyone listen to podcasts? If so which ones. I don't have an Ipod but my ZVM has Zencast. I never really set it up but I was curious as to what I have been missing.

    Any good books to make me smarter? :):)

    Any one read any "must read" books lately that they learned a lot from? I am always looking to broaden my knowledge base. I am getting a PhD in mechanical engineering so I get plenty of technical training in math and science. Since I eventually will be working in industry, I want to...

    CX-300's pop when I insert/adjust them

    I had received a pair of CX-300's off of ebay that turned out to be fake. The right earpiece would pop loudly whenever I inserted or adjusted it, I assume pressure buildup caused the thin plastic film on the driver to suck in or out and make a crinkly popping sound. It would drive me crazy so I...

    Show us your IEM case

    Because I am obsessed with keeping my IEMs pistine (as well as everything else I own), I really needed a case that would prevent scratching. I made this case out of an Altoids tin and microfiber cloth from Walmart ($1.80). It is the same cloth I use on my high end optics (believe it or not) so I...

    Discussion on impedance and difficulty of driving

    What makes one headphone harder to drive than another headphone? I would imagine that lower impedance headphones are harder to drive because they draw more current (P=I^2*R) for the same output power and the am might be current limited. Alternatively I can see that high impedance headphones...

    Noise canceling add on for headphones?

    Does anyone know of a noise canceling add on for headphones. I noticed in my Gigabyte soundcard menu that they have a noise canceling feature. Unfortunately I don't have a mic to try it out but I am curious to how well it would work. Anyone know of anything else?

    Need help from Professional Audio or Electronics Person

    I am currently filing a dispute with my credit card company over a Zero that I purchased that was defective. Something is seriously wrong with the headphone amp on this Zero because it melted a pear of earbuds!! I measured a DC voltage of 12 volts on the headphone jack, clearly indicating...

    Can accidentally turning up the volume for seconds cause hearing damage?

    On my computer there is a delay in Foobar when you change the volume. The other day I accidentally turned it up way too high because it didn't kick in for a few seconds and when it did I had to pull off my headphones (DT770's out of my Zero). I have no idea how many dB it was and it couldn't...

    Does anyone understand the stock market?

    I just started trading stocks (I know, great timing) and therefore I am trying to learn everything I can about how the market works. First, aside form the IPO and the rare occurances when a company floats additional shares of stock (or the even rarer event a company will buy back some of...

    In response to Post Your Photography, how do you take a great photo

    I recently started in the hobby of digital photography and digital editing. I have a Canon Rebel Xti and an ok 17-85 mm Canon lens (not the kit lens) as well as a decent 50 mm prime. I do most of my editing in Photoshop and can do some of the more complicated actions like removing a background...

    Hearing damage from noisy car

    I have an old Jeep Cherokee and its noise insulation is pretty bad. I like to listen to audiobooks while I drive but once I hit about 50 I need to turn up my radio so loud (volume about 17) that I must be around or above 85 dB. I am worried about hearing damage. Anyone considered this a problem...

    Potentially good idea for improving sound out of cheaper headphones

    After reading about why electrostatic speakers and headphones sound better in certain areas being due to the lower inertia of the driver which translates into less severe artifacts of the driver such as resonances, quicker response, and quicker decay of energy. If you were to model your...

    Science behind burn in

    Coming from a very technical background I was fascinated by the concept that electronic equiptment would experience burn in. Does anyone know any definitive science behind this, which components (caps, inductors, transistors) are responsible for the supposed burnin in of amps. I am also a little...

    Can't hear soundstage

    So I didn't really know how to title this post but basically my question is what is required to hear good soundstage. I have Sleek SA6's IEM's and HD497's and I assume I should get some kind of soundstage out of them. But I don't even really know what to look for. Supposedly you should be able...

    Can't you just correct any problems in sound signature with EQ??

    Everyone compares headphone X to headphone Y and says that X is brighter, more emphasized mids, etc., I prefer using headphone X for classical and headphone Y for rock, etc. Well if a particular headphone does not emphasize the treble or does not emphasize the bass, can't you just "fix" this...

    How do you know if you are listening too loud

    I listen to music for almost 8 hours a day some days. I always have my Zen Vision M and Sleek SA6's on me through my day. After reading many articles about damaged hearing that our Ipod generation will be experiencing, I became paranoid. I have my volume set to between 8-10 (some times lower)...
