Headphone Amplification

Well, I had to send in the red hat proto to craig to fix. Unfortunately, it is deemed "unfixable" and Craig refunded back my money. So I'm ampless. I will probably end up getting the balance discrete he is coming out with, but he gave me a time frame of late January. Knowing craig it will probably be a couple of months after. So in looking for somewhat affordable options that I can use now and sell later when its time to get the balancing act from EC, i thought of woo audio. Affordable and KG has had nice things to say. The woo audio 6 is a transformer coupled amp that uses the 6DE7 tubes for driver/power and a 5ar4 for tube rectification. The only question would be ho…

is this worthy of consideration as an all-in-one dac/head-amp option for low-impedance single-ended headphones? https://www.bursonaudio.com/products/conductor-v2-plus/

This probably dives me more insane than anything else about this hobby/obsession. So I finally make the switch and have all my music into a 5g iPod 60gb, I get the awesome Turbodock II for the line out and am using my fully burned in Hornet. The Hornet sounds awesome... nice texture, black background, good weight/depth, etc. So why did I put it on eBay... I miss the crossfeed and bassboost from my SM for some of my music. Damn I hate this! I wish I could keep both but without the parametric EQ some of the music I listen to sounds slightly too dry with this amp, which is frustrating because I'll switch to a different album and it's bliss! So off I go to sell and on…

As usual I'm at a disadvantage as I never seem to be in the right place to hear the gear I'm interested in. I've pretty much ruled out tube amps (yes, they sound wonderful) due to the placement of the amp in conjunction with where i sit. It's a heat issue. So solid state it is. Wondering if anyone here has has the pleasure of listening to both of these fine amps and can share their respective strengths/weaknesses. YES, I know the GSX can accomodate balanced cans. Yep, I realize alot of folks have not heard the P1. If it matters I'll be feeding it with the Bel Canto Dac3. Any other options I should be considering at this price point? BTW, I know I can order bo…

Does anyone here know/remember the specs on the Moth EC2a3? Trying to determine the headphone and speaker output impedance.

Hi, I’m going to use 6SN7 in my 006Ts and would like to choose something modern; going through tube specs from Psvane and Linlai it is not clear if their 6SN7 (and CV181… as here they declare only 600mA for filament that is quite strange) can work up to 330V that is the value inside the 006 in their spec (when available) we have Ua (static) … 250V Ua (maximum)…. 450V here is an example … http://www.psvane.com/en/hifiseries/327.html is there anybody that have experience about? are modern tubes suitable for use inside 006 (and similar)? any suggestion about which one should/could be choose? thks 🙂

This is my fist posting for this forum. I hope it’s to your liking ! Apart from the audio qualities, I am also interested in the technical qualities of equipment. So my posts sometimes will be a bit technical. Just skip the uninteresting bits. If that is almost all: so much the better. That way you have more time left for enjoying the music ;-) Quite recently I finally managed to obtain a Stax SRA-12S pre-amplifier with built-in ES headphone amplifier. According to the previous (first) owner the amp got very hot. Well, since it is supposed to run quite hot, I was not alarmed and bought the SRA-12S unseen (well…. just a photo). Unfortunately one channel of the …

I finally picked it up and it doesn't disappoint... Jesus this is bad and one funny thing, the surface coating on the chassis is very different from the CarbonX. Same quality parts, ZWEE output socket and the "legendary" SANNI volume control i.e. crappy Alps clone. Now the chassis is the same one as the CX but much better surface finish. The other one scratches very easily (as in I've already scratched it) but this one seems more resilient. One funny thing though, the hole for the tube doesn't quite line up. I tried to take a picture of it but it might not be as apparent as in real life. The space on the right is quite a bit bigger than on the left... N…

Hey folks, what are your thoughts on the new high end stuff like the B52, the PPX3 XLR and such like that? I've heard that the B52 will cost in the 5-6000 range, anyone hear anything directly from Ray or otherweise know anything about it? It's made the rounds at a few meets now (most recently the Boston Meet), but things seem really tight lipped about the thing. What is it exactly? A headphone amp that also has preamp functionality? A preamp that is also a good headamp? (yah yah a headamp is basically a specialized preamp, but you guys know what I mean)... Any ideas on the tube complement? The 5687s x 4 seem to have been identified, but what about the other 4? they se…

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.

I kid you not: http://www.monoprice.com/Product?c_id=120&cp_id=12008&cs_id=1200801&p_id=11567&seq=1&format=2 Looks like a candidate for the Inner Fidelity test bench.

Now that this amp has been released and we finally have an internal pic, it is time for a dedicated thread. Here is some info about the launch event: http://hifilounge.tumblr.com/post/162193518708/trilogy-h1-energiser-for-stax-earspeakers-launch So 5000UKP... and nothing else which is relevant at all. The usual HF retards claiming this was the second coming and all that BS but here are the internals...enjoy: Not the best quality but good enough to know what is going on. In before Jim and yup...this looks a lot like an SRX. Some Russian dual triodes for the input and those look a lot like 6N6pi's to me. Two plate resistors as well. So over a…

I've got two bad 6sn7s. What do you personally do with your tubes once they go badly microphonic? Do you just throw them away? Is it worth it to try to open the tube up so maybe I can check out the insides, as an educational experiment?

Hi guys. I've owned to Xin amps (Supermini III and Supermacro LE) and I don't think very highly of them. On Headfi, Xin receives a lot of praise, especially for the Supermicro and the Reference. After my experience with the other two models, I'm not very keen on trying either. Has anyone had experience with Xin? What do you think of his work?

Earlier today I came across the pictures from ETF '07. http://www.dhtrob.com/etf/index.php?start=23 This is a picture of a totally out there headphone amplifier using transmitting tubes. Those tubes are around 7" tall, and the plate dissipation is up to 100W. For a pair of headphones. And though it's not a headphone amp, this is just stunning.

Hey Kevin: how is this amp progressing? Last I read you had build a proto and seemed happy with it. Was that last board layout tested? I'd like to give a hand testing if needed.

I know these are both DIY amps and they all have different sounds depending on how theyre built, but I'm looking for a warmish SS amp with a good amount of bass for my 225s that delivers enough current to open the phones up. I'm trying to spend as little as possible (under $300 but hopefully around $200) and usually DIY beats commercial amps in terms of bang per buck. So which amp should I get?

I'm debating which amp I should get. Right now, I have a home based Pimeta. I would like something warmer though. Which of these amps should I get? I only use Grado headphones (sr225 and sr100) thanks

Currently just a pic on the home page, but looks like Craig's getting into the 'stat amp market: http://www.eddiecurrent.com/ Edit: OK, so google points to discussion about it on the other site including (as would be expected) some of the usual suspects here, so to the stool in the corner with a pointy hat for me and a note to self to check the other place before posting startling revelations that everyone already knows about.

Removed due to wrong board post, please delete the thread

Do you like stepped attenuators in your amps? I had one in my Corda HA-2 MKII SE which I've since sold, and find myself missing it. I never really had the problem of finding the "right" volume level that other listeners have. Right now, I think I will definitely have one in my next amp. So, what is it for you?

So the amp arrived today. I got it set up, turned it on and no sound. I then noticed that the 6C33C tubes were not lit up. I shut it down and turned it on again and slowly the tubes came to life. i had it playing for about an hour and the sound slowly faded as the 6C33C tubes shut down. Any idea on the cause. I am waiting to hear back from the seller and I'm guessing I will need to send it to Craig to repair.

Ok, am wanting the SR-L700 model and am TOTALLY confused as to which damn amp to get, we have the SRM 006ts, 353x and 727 mk 2 . Are tbere any other brands that can be better suited up to this price ceiling?

I guess dCS decided that headphone-based systems are now worthy of their time: https://shop.dcsaudio.com/products/lina-system Figured most people would be interested in the amplifier so I put it in this section: DAC includes crossfeed EQ (didn't look into whether it was software/hardware), compute module on the side for either Roon or whatever dCS decides to do in-house. Looks like a scaled down version of their ubiquitous Ring DAC External clock lets you use the DAC with OCXO's instead: Full system cost seems to total 29,150 USD. Price aside I think the casework is pretty cool, I saw esoteric do similar things with some of their new …
