Hello, I am designing a tube amplifier for headphones and am stuck trying to design a cathode follower. I am not looking for any tips or rules of thumb. The output of my amp is the cathode of a double triode and i used both a resistor network to ground and a 220 uF cap off of the cathode for...

Hello everyone. This is a comparison review between the esw9 and esw10, as they are both currently in my possession. The test equipment was: hooray for pictures: headphones: Audio-technica ATH-ESW9 (almost a year of moderate use), Audio-technica ATH-ESW10 (almost a day of...

Hello everyone. After searching the forums for recommendations, I see that no one has really cared about surround headphones for a few years (perhaps this should tell me something). Anyways, I am doing a research paper on the potential advantages and disadvantages of mixing music for 5.1...

Hello headfi'ers. I don't know if you guys know about knol, the google answer to wikipedia. Well, I decided to take it upon myself to get an article for headphones going. I thought I would start this thread for people to give any ideas or anything they feel should be involved. I intend to be...

So I was wondering, does this community know of any DAPs (cdp, mp3, whatever) with high quality DACs? I know through Red Wine Audio that the 4th and 5th gen Ipods had one, I'm not sure of the quality of the one in my A2, but are there any others? I ask this because I am trying to find other...

Hi there amp guys. I want to design and build a quality tube amplifier for my master's thesis. I have a bachelors degree in electrical engineering and have built some simple, solid-state headphone amps. I want to step it up a bit and do a high quality tube amp now. What I am hoping to get...

So before I start, I am mixing my newer music for headphone listening, so don't give me that "oh well, you should really be mixing with speakers" line. I have heard that the now-discontinued AKG K240 are great headphones for mixing. can anyone here comment on that? what about the newer AKG...

my friend is thinking of buying a pair of the Bang and Olufsen A8 earphones and i was wondering what you guys think of them. After the search I did on google all i got were good reviews of them. not trusting the mass internet media, i searched this website and got only a couple useful threads...

so i have a pair of the Alessandro MS-2s (not the new ones) and a pair of woody/silver recabled SR-225's. I decided I don't need two pairs of sweet grados, just one. So i was wondering, if i sell them both, do you think i'll have enough money from the sale to buy a pair of new of like-new RS-1's...

is there a true line-out (like the sik-din for the ipod) in existance for the Rio Nitrus? I built an amp for a friend who has a nitrus, and i've scoured the web for a line out for that thing but had no luck. can anyone tell me where to find one, or if i am not going to find one? thanks a lot...

my friend bought this CD player from a want-ad seller for 500 dollars american. it is in a supposedly unopened box and is brand new. from what i can tell he got a good deal (it looks pretty awesome but we he hasn't openned it yet). anyways, does anyone here know what the retail price of it is...

Im just bored and curious as to what people think the best looking headphones are. I'd have to say either the Ms-2, the HD-595, and the ATH-W1000. Any other opinions? note: credit for the MS-2 picture goes to either thefinder or Shang-Ti Chen, i can't tell who took it, but they are off...

I use an SR 71 for my amp and it has a 1/8" input jack. my 225's have an 1/8" inch plug. i have the grado 1/4 to 1/8 and everythings fine (no sound quality loss, as far as i can tell) for now. Im wondering that when my phones come back from being recabled (with higher quality cable) will the...

I don't know where else to ask this, but I want to buy a pair of headphones from a headfi member in In The Netherlands. I live in the US. Neither of us really know how to deal with international shipping, duties, insurance, customs etc. could anyone here explain this stuff to me? i know it's...

go to APC's website click "music" then "listen" then the song. I like it... i don't know, anyone else?

where can i get good adapters described in the title? anyone know?

...And all its ampy goodness. sorry, just expressing my love for my amp. IS THAT SO WRONG!?

I was wondering if the headphile.com "woody" modification for the grado 225's was worth the extra $265 for paduak or $300 for the bubinga or purple heart, i mean in terms of sound quality. They sure look amazing (I emailed Larry for a full size picture and i have it as my background. If you want...

Has anyone else heard it yet? I don't know if it's released yet, but that's not the point. I'm listening to the title track "IM The Supervisor" with my SR-71'ed 225's, getting assaulted by bass and loving every minute of it. You can get clips here. I can't wait.

I want to get a new pair of headphones but there is so much out there and i keep finding more and more options. first i was going to get grado 225's, then i found out about the allesandro ms-2's and decided on those. then i got ety ER4S's and returned them after realizing the in-ear thing was...

Im buying a new sound card with a max price in the 80 USD range. My only requirements are quality sound and can support front and rear speakers (4.1 i guess) please please please can someone give me some recommendations? thanks -AJ

Does anyone know of a website that is basically a database of headphone specs? it may not exist, but i'm curious. I know you can't really just look at specs and know exactly what each pair will sound like, but numbers are useful, nonetheless. Wouldn't it be great if you could just select a pair...

I was hoping someone could recommend me some good piano music on the soft side. preferably no vocals either. All i have in that catagory is "the Frail" by Nine inch nails of the CD "the fragile" and the piano solo in that remix of Clubbed to death by rob dougan on the matrix soundtrack. any help...

could anyone please recommend me a decent sounding amplifier that i could buy or build that is also portable? by portable i mean fits-in-a-backpack-and-leaves-space-for-some-other-things. I use a Rio discman and grado SR60s which are soon to be upgraded to MS-2's. As always, any help from the...

Hello people. I have been a Grado fan for a while and after visiting their website, they have 2 series listed, The RS and the SR. After looking at KR...'s "Headphone Lust Museum" photo album (which is pretty awesome, good job man) I've seen that they have other series such as the HP, alessandro...
