Headphone Amplification

They look pretty neat. Here is a link to the site in Japanese, but it shows a bunch of pics: [url=http://www.soundhouse.co.jp/shop/SearchList.asp?i_type=m&s_maker_cd=1617]IZO

Hello! Please let me know which you would prefer and why: 1) The CIAudio VDA-2 DAC and VHP-2 headphone amp, both with VAC1 power supplies. OR 2) The HeadRoom Balanced Desktop. This model is now only available with the Home Modules and Home DAC. I will be feeding the DAC's optical inputs via a SqueezeBox Classic. Headphone suggestions welcome. Is going balanced worth the hassle of recabling headphones? Music preferences: Primarily Rock and Acoustical. E.g. Rush, Pink Floyd, Jose Gonzalez, Dire Straits. Channel Islands Audio HeadRoom Balanced Desktop Amp @ HeadRoom - Right Between Your Ears Thanks for your feedback!

Hello all, First a little background: I recently switched to cranking my GS-X up to high gain and then a buddy came over with Edt. 9s I heard hiss (even when the volume is set to zero). I checked and I can't hear the hiss with my HD650, D5000s or SA5000s. I tried my Shure SE530s and the hiss was there with them too. I did all these checks after disconnecting it from my DAC3 at the back of the amp. On medium gain the hiss is inaudible with the Edt. 9s and slightly audible with the SE530s. On low gain the hiss is barely audible with the Shures when the amp is cranked. This all makes sense since the gain switch is in the feedback loop on the amp so it should drop gain …

Can someone lead me to more info on the subject? I googled what I hoped would be some good keywords to get me to a thread or something... no luck

I'm seriously considering purchasing one of these, and as of right now, is the only amp on my list. I've gone through and done "research" on many other amps close to this price, and the GS-1 seems to be extremely flexible with the headphones used (ie wide variety) and seems to be a top-notch amp. The GS-X, despite how badly I want it, can't afford it. Maybe I missed one, that you guys can recommend. And what's your opinion on this amp, for those who have listened or owned it. Any other recommendations on amps at/very close to $1,000? I'm not totally set on which HP I want, but am considering both the RS-1 and Senn 650 w/upgraded cable, or SR100's w/HP1000 drivers. A…

Anyone else notice this? hmmm.... ALO Double M3 amp - Head-Fi: Covering Headphones, Earphones and Portable Audio

It's been a while since Justin mentioned the new modules... I know he has been having trouble sourcing some of the parts. Has anybody heard the new modules yet? Also, are they being used in the GS-X as well?

AFAIR, there is a diode after each 9v battery, and two sets of caps between V+ and ground and V- and ground each. There is a series resistor inside each 9V rechargeable lithium battery, as I recall, but I can't figure out why they won't work with the SR-71. Any ideas why?

I am looking for a compact amp with a line out for my desk at work, so I can keep my crappy powered speakers plugged in too. Source is an iPhone 3g dock, headphones are most likely k271's, if not them, either DT770's or DT250's (I need to hear the k271 first). So, assuming I go with the k271, I am guessing I'll want to err on the warm side of neutral, and I'd really prefer something with a small case and wall wart as "desk" and "office" are really words too strong to use for what they give us. My understanding of the mini3 is that it isn't easily modified for a lineout (but I would be happy to be wrong - I love the mini3). Battery functionality isn't important, but …

i found some internal pic of this portable amp, and posted in the headfi thread. http://www.head-fi.org/forums/f105/rudistor-xj-03-a-347133/ some1 pm me asking me to remove it. was there something wrong i did posting internal pic to be share with other? anyway,what do guys think of this amp? some1 in headfi reckon it's better then the pico, it look like a ra-1 to me?

Please post a picture of your SR71a completely immersed in water. Does it refract light differently than the Predator?

Hi, I am not sure if this is right sub section for this and this is my first post a head case My requirement is following: I need to be able to share my music with my gf. So, the main question here is, can I use a y splitter with any amplifier. Lets say with a pico? Or do I need to go only for units with 2 headphone outs. I need a single unit as my UAB DAC/Headphone amp for convenience of moving it around. I am ready to shell out around $1k for the unit apart from headphones. My choices with 2 headphone outs: 1. Meier Audio Opera/ Symphony - Symphony is really costly and for Opera I am getting only the 0,120 ohm versions. Shouldn't I need both h/p outs as 0 ohms 2…

I'm thinking about upgrading my headphone amp, and since I'm using my Nuforce Icon for headphones right now I might as well upgrade my speaker amp at the same time. I've heard good things about the 840A, but not much about its headphone amp. Anyone have any experience?

I thought it was about time my cheap ass got a cheap headphone amp (I wouldn't be so cheap if I wasn't so broke ) and due to the overabundance of orthodynamics in my collection I need something with a good bit of powah, so far the only ones I've found that are both cheap and powerful seem to be the Darkvoice amps @1w. I'm thinking the little Figaro or 336. I've heard and liked the 336 but heard not the Figaro and that one is cheaper and looks less vulnerable to my clumsy ways. Anyone here heard one and have an opinion of it as a smallish and cheap workaday amp or others similarly priced ($200 inc shipping) with enough juice to run orthos?

Well here is some fresh meat for the peanut gallery. I got this off our resident gear whore Tyrion a while back in a gear swap. The Berendsen IPA 80 is from Germany and retails for about $2000 but they recently pulled out of the US market. From the website and visually there are three transformers one for the pre and one for each side of the amp. They talk about the power of the amp coming from ring emitter transistors ( I have no idea what the fuck that is). I will say this cleanly slays the Krell 400xi I owned briefly and thought sucked. The main bonus this amp presents in a killer headphone amp that is so ergonomically challenged it has me questioning the designers…

I just unpacked a box from our last move in 2005. I found my HPA V. 1.0 but no power supply. When I packed it to move it was acting up so I just want to get workable power supply to see if it actually works. I believe the basic power supply for the HPA was 12V and 800 mA. Can someone confirm or refute this. Also if you know the dimensions of the power supply tip that would be helpful. Thanks.

Written in Sam Tellig's column in September 2008 issue of Stereophile. (The October issue just hit my mailbox so I'd say this is open to post now.) Musical Fidelity X-CAN V8 tube headphone amplifier...and line stage? If a local dealer has Musical Fidelity's new X-CAN V8 headphone amplifier ($550), by all means audition it. This is easy to do. All you need are your ears, the space between them (plenty in my case, according to David Janszen), and your headphones. There was never an X-CAN V4, V5, V6, or V7. The previous model was the V3. The implied improvement is as if the X-CAN has leapt five generations, from V3 to V8. It's easily the best X-CAN yet from Musical …

I have some experience with the DIY. This project looks quite easy and using cheap parts ( that is important, cause i am used to burn them a lot lol). But do you think the Amp will perform better in balanced configuration. I have HD650 and will use balanced source.

-=Hey Guys=- I have my 880s and 650s in another room and was wondering if my 701s can be powered by my Woo3, without distortion, if volumes are kept low. I understand the problems the "3" has with low impedance headphones, but I'm wondering if it's a volume issue, where more power is called for, or it just won't perform at any volume level because the volume control is an attenuator? Thanks USG

I'd like to get a longer USB cable for my Pico so that I can sit on a couch probably about 10 to 15 feet away from where my computer is. I know I could get a headphone extension cable but I like to be able to control the volume and a longer USB cable would minimize the extra connections an extension would add to the mix. So my questions are, is there a maximum length for USB? If a longer cable is possible does anyone know where to get them in such a length because they're not available round these parts?

the Rawsonte First Watt F5 clone off Agon. He immediately removed the listing as soon as I paid, so I don't have a photo, but I can't believe I caught his ad exactly when he put it up and got it I plan to drive various things with this 25 watter, including HE Audio He1.2b electrostats, Sennheiser HE60, and my various speakers.

So I'd like to get a small desktop amp to power my SR-44 setup from my laptop and I was wondering what other options aside from a T-Amp might be out there? Budget (Sub $100 would be preferable) or something along the lines of the Starving Student Millet for speakers would be awesome if such a thing exists.

Someone in my country is selling one of these for 1000 euros + shipping in a quite good condition. It has separate power supply (as every Gilmore Reference I guess) with oversized trannie, Blackgates internal Vampire wire and is fully balanced with separate RCA and XLR inputs and also SE and balanced outs with a switch in the back to chose either RCA or XLR, and separated stepped attenuators for each channel. I'd be thankful if anyone could tell me what was the original price for this amp, whether in your opinion it's worth trying it at that used price, and some technical specs, which I haven't found at the Headamp page. Considering I already own a RPX-100 and a H…

One of these just came and went on Agon for $845. Looks like a whole lot of happiness for the money. Anyone know anything about the builder? 807 Tube Stereo Amplifier

I figured I would start a thread on the above amp I just picked up. A real beauty and sounds gorgeous. I believe this is the exact model that Kurt owned, Saint1 owns (from James3toe who got it from a user "Bob"), and Nightfall. One of only 5 that Craig built that was supposed to develop into an actual EC 2a3 line with the top of the line black rose being at the top of the lineage. By far the si2a3/45H is the best sounding of the different moth 2a3 iterations and may be slightly better than the ec2a3 version due to the external power transformer and inductor chassis. Power supply is all film caps as well, same output transformers. Now I …
