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...

What a good amp that isnt too expensive for the dt990 600ohm?

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...

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/  ...

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.

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...

Hi, I'm looking for my first pair of headphones AND Amplifier. My use will be strictly for home. I have a desktop with only on board sound. My budget is $500 Canadian and I am only looking for a amp (not portable but not too big either something easy to carry when moving because I am a student)...

Just won one of these on ebay.. wondering how does it sound... anyone know about them? Seems kind of old though...

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...

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

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...

Edits 2012/03/21: Added new analyses 2012/03/20: Added Bottlehead Smack 2011/02/12: Added Speedball Crack with 5998A tube in audio analyses, modified the headphone analyses to add the new measures. 2011/02/11: EHHA vs Castanet with the Grado HF-2, audio analysis for the k601 and...

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...

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...

What’s that?  You’d like a review of the smallest fully balanced portable amp in the world?  Why I’d be happy to, here you are my friend.         But before the write up, I must offer special thanks to Ray Samuals for asking me to review his latest amp.   Ray has been a strong...

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...

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...

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...
