Headphone Amplification

Well, my problems with the Val E10 continue. After 5 days with it I'm done. At this point I'm really tired of messing with this. It has taken up way to much of my time. I got the replacement tube yesterday, and of course I still have the same problem of a buzz and no music after about an hour or so. I think instead of wasting anymore time I'm just going to order the WOOAudio 3plus. I don't think it will have any trouble with my K701's, and I should easily be able to get tubes, and repairs for it. Do you know anything about these amps? The 3 plus was beefed up to handle the K701's better. If you have any info on this amp let me know. I'll be ready to pull the trigger in a…

Is this true? Has anyone opened up the HPA-1? And are there schematics for the HPA-1? Danke

Has anyone heard this amp with AKG K701's? Does the amp have enough output to drive them to decent listening levels? Looks well built. How does it sound?

Hi all, First post here. I was wondering if the 6922 has less gain than a 6n2 tube, and are they roughly interchangable? Thanks.

My MPX3 in the toaster variety isn't turning on. Any suggestions?

Just ranting aimlessly. So I have a GCHA now. At first it sounded exhillirating; the amazing soundstage that is. But after listening to it for a while, my music just sounds so slim and uninspiring. I'm sort of a quiet listener, but it still sounds lean even when I turn up the volume. Maybe I'm just realizing the true nature of the K701 I'm using. (I also purchased the K701 recently and haven't tried it out of an amp other than the GCHA before.) Maybe I should have gone with a tube amplifier in the end after all despite having always thought I was a SS guy myself (high speed and punch). Female vocals are totally dry but I guess that is expected from a SS amp. However, I h…

link Comments?

I saw this pic and I thought this could be something new and interesting to try out. But then I saw these posts from the Tube Asylums and this unit sounds like a build quality/ customer service nightmare! http://db.audioasylum.com/cgi/m.mpl?forum=tubes&n=190381&highlight=frihed89&r=&session= http://db.audioasylum.com/cgi/m.mpl?forum=tubediy&n=116589&highlight=frihed89&r=&session= http://db.audioasylum.com/cgi/m.mpl?forum=tubes&n=190718&highlight=frihed89&r=&session= http://www.audioasylum.com/forums/tubediy/messages/116891.html I know Phil sent his McAlister amp back for some changes. I hope he is having…

and so the amp parade begins A bit of a disclaimer I am NOT an audiophile and will never claim to have "golden ears". I am just getting into this world of headphones. Right now I have the Senn HD-650 and AKG K-701. I have had one amp for a few years now a Headroom Coda Amp LE so that is my frame of reference. The few things I don't like 8-) about the P1 is that the top and bottom seem to have been coated with some oil and grease magnet ( the PSP has nothing on the P1 as far as revealing any and all contact with the top and bottom) the side however have a narrowly spaced ribbing that I rather like. Its not really something I didn't like but something that may b…

Per a ravenous consumer on HF, Justin is making an upgrade version of the BH - any clues? Justin, would you comment?

Well my new SinglePower amp arrived today. It has two gain stages and uses some nice powerful tubes as the output tubes. Here's a bunch of pics:

Wow, a few minutes at this site is like a slap in the face after spending a lot of time at head-fi. Apparently I own the ultimate "hella shitty" amp, the PA2V2. I always thought of this as a temporary solution, necessitated by my purchase of an ALO dock connector (also apparently crap), and for $60, why not? It seems that there is some consensus here that portable amps are kind of silly, and do nothing to improve SQ, esp. if your source is a DAP. As my source will be either a laptop or iPod (maybe iMod?) for the foreseeable future, and I need my gear to be portable (out-of-the-reach-of-children portable, room to room and home to office portable, not walking around…

Hello It occurs to me that the Cary 300sei is selling mostly under 2K on A'gon. which gives me the impression that maybe i can start thinking about trading in my ZD.... anyone have any idea about how these compare?

I have posted some over on head-fi about this amp so I thought I would start a thread here too. The Extreme is THE AMP under< $1000 from my experiences. This amp is so good for such a modest price I am still trying to comprehend how good. Every positive characteristic you can identify seems to be present in copious amounts .... soundstaging, tone, dynamics, bass slam, "midrange magic" etc... This amp particularly elevates the 580/600, and the power of this amp has my Alessandro M2Si rocking along, in addition to giving the M2Si a soundstage well beyond what I have heard from any Grado headphone previously .... even using senn yellow 19545 pads. For you guys wanting an …

Good Day, I'm wondering if you'd be so kind as to reply to some questions I have. I am just getting into this hifi headphone world. I want to hear your thoughts good, bad or otherwise. here we go, I'll start with what I have. Senn HD-650's and have a cardas audio cable coming in the mail atm. I have a headroom coda amp le ( It just don't seem to cut the mustard) therefore my endeavor for better stuff. The more I look around and research the more overwhelmed I get with the seemingly endless list of choices. I try to take anything I read on forums with a grain of salt as I know that most posters push the products that they own as being the best, as it helps…

Relatively new around this forum, Ive lurked before but thats chnging now. Looking to OP amp roll my PPA. Its running with a 24V ELPAC. Would it benefit from a better P/S? What are some BASSY, open sounding OP amps for it? I have some OPA2107s, can those just drop in? thanks!! Garrett

Complete noob needs more advice please. I need a budget stationary headphone setup for my home exercise bike. I need isolation as the bike is very loud and I already have some mild high frequency hearing loss. I'm thinking of getting an oppo DV-970 HD universal DVD player for a source. And etymotic ER-4P In Ear Monitors for their isolation. What should I use for amplification? Does the line out jack have enough power that I would need an attenuator instead of an amplifier? What about a Cmoy type amp, on ebay, with the builder optimizing a low gain for the ER-4Ps? Or do I need a real amp, like a headroom Micro amp? If I bought the Headroom, do I really need…

Hello everyone, I'm new to the forums and was hoping that you guys could help me out. About four years ago, I went out and bought a pair of Sony MDR-V600 'phones for $100. Although far from audiophile quality, they gave me a taste of what I'd been missing out on. Well, I'm now 18 and have a steady flow of pure spending money coming from work, and I'd like to step it up a notch (or several notches at that) and get the 'phones of my dreams. I've got my sights set on the Sennheiser 600's (possibly 650's if I can find 'em cheap enough), but now I am at a loss of what sort of amplifier I should purchase along with the 'phones. I will be using a CD player a lot with them, so…

http://www.head-fi.org/forums/showthread.php?t=215264 <GE> suppose he paid for any of that <GE> that stupid dock is going to break his ipod good seriously, the review makes no fucking sense at all. just another example of shameless headfi marketing. i am willing to bet 10 bucks that the UE-10 pros sound best straight out of the ipod.

Hey guys, wanted to ask you for some advice. I'm about to make an amp purchase and I've always wanted to hear some of Justin's amps. However now I'm stuck in one of those am I making the right decision by spending this much money for the source that I have. What's my lame source? An iPod with Lossless codecs going through line out. I know its not the greatest source but it's also very hard to match the convenience of an iPod. This is mainly for office use so I'm not in the market for a portable amp anymore. I'd rather invest the money into something a little more solid. So I guess my main question is... Is the GS-1 overkill for the iPod or should I just stick …

Do I need to do anything to run balanced headphones out of the XLR outputs on the Lavry? Can I simply get someone to recable the headphones terminated in female XLRs or do I need to do something different? I currently have the jumpers in the Lavry set on balanced output mode.

I only have a rough daswing at present.

Right, another one of my "x vs. y" threads... I've been going back and forth with a guy on head-fi about buying his SLAM SE, and it seems he's not really interested in selling it anymore (after I sold off my whole rig ). I have a WTB ad up there (and here), but it got me thinking about whether it was worth buying used. Anyway, I fired off an e-mail to Mikhail about it, but I think I'll probably end up with a used amp, since I'd need it by January to take advantage of the fact that my dad will be in PA for a couple of weeks (no tax makes a HUGE difference!). While I was considering that, something that's always been in the back of my mind came up. I've always been cu…
