    Clarification: OTL VS transformer coupled specs

    Just noticed on Woo Audio's website, that all the OTL amps have a better spec versus transformer-coupled amps for signal-to-noise and THD. http://wooaudio.com/products/wa6se.html http://wooaudio.com/products/wa2.html   S/N is 95 for transformer coupled and OTL is 98 similarly THD for...

    Custom Bottlehead Crack, assembled by "hifibuilderguy"

    Greetings!  I wanted to post some initial impressions of the custom Bottlehead Crack that Shawn Phelps (aka hifibuilderguy) recently completed for me.  After owning many of the TOTL headphones available, I kept finding myself drawn back to the venerable HD600 and HD650 for their combination of...

    [Review] Ortofon HD-Q7

    This little powerhouse is almost unheard of here on headfi, which is a shame. Reviews online are practically nil*, and to the best of my knowledge ALO Audio is the only distributor in North America. edit: Headfonia posted a review a couple weeks ago: http://www.headfonia.com/ortofon-hd-q7/  ...

    Tube amp with low impedance Headphones

    Is it a bad idea to use a Tube Amp with low impedance headphones? I currently have a Glow Audio Amp one, and I'm looking at purchasing the Audio Technica ATH-AD700 phones, that I believe only have 38 ohm impedance or so.

    Poll: List of Amps for HD650

    I know there are tons and tons of threads on this topic, believe me I'm reading a lot of them. I thought something more current might help some newer head-fier's out.   (ahem, me for starters i guess)   To keep the thread respectable, there's a given list of what two amps (users can...

    Most powerful headphone amp?

    Not being an electrical engineer I don't know about voltages and current and the like, so when I say 'powerful' I just mean which headphone amp can drive the **** out of notoriously hard to drive 'phones like the K701 with the volume knob at about 9 'o' clock (ie. without even trying)?   Can...

    Can any one compare the Bottle Head Sex amp (and low impedance head phones) with the Crack OTL amp (and high impedance phones)?

    And, or have you ever listened to the Bottle Head Crack amp with K701s?

    Which setup for $600? DT880s/600ohm?

    Edit: I know how boring a wall of text can be in a thread, so I cut some things out and bolded the important parts just to make it a little easier. Also I changed the title to hopefully make it a little more interesting. Thanks!    Hi, all,     First of all, this is a really informative...

    HELP with W1000x

    Just got my W1000X today.   Is my head too small or it just fit loose on your head, I can't move freely....is there anything I can do to fix this problem.   My other questions is, it sounds to me that the mid range is kind of laid back, is that how it supposed to be? Or could be a...

    Crack;Bottlehead OTL

    Maybe the subject heading is a little confusing for folks that aren't used to Doc Bottlehead's tendency for naming his DIY kits a little differently than the run of the mill audio company. Doc's just announced a new OTL headphone kit called "Crack". If you've ever been interested in...

    AKG Q701/Matrix M Stage vs HD600/Bottlehead Crack

    Anyone ever has had a chance to listen both would give a suggestion. I heard the HD650 with Bottlehead crack, and they sound amazing. They were very warm, smooth, marvelous sounding, but i never have a chance to demo HD600. AKG Q701 that I have now sounds super phenomenal, very clear, detail and...

    What DAC should I get to pair with Bottlehead Crack (under $300)?

    I have never heard music come through a DAC.  I have just purchased the HD 650's and the Bottlehead Crack kit.  That's already a bunch of money.  Can I get by with something inexpensive like the Fiio E10?  Or would I notice a huge difference with something more expensive?  If so, what would you...

    ALO Pan Am vs Bottlehead Crack and HRT MusicStreamer II +

    I had been planning to buy a HRT Music Streamer II + and build a Bottlehead Crack, but ALO is selling the Pan Am at a discount today and I am very conflicted. If any if you have seen my previous threads, I was looking for a transportable amp for my HD650s, and...well...I just wasn't able to...
