Hi there. So like the title, I'm looking for an LOD cable for micro USB plug (android), for my phone. I tried the search box, but the newest topic with the same problem was back in 2014, I think, so I thought I might give it a shot. So my phone is Redmi mi2 (old but good phone), and I...

  Strange, it could drive my HE-400 and AKG 701, which are a bit low in efficiency, with no problem at all. 

  Genalex is brand new/still in production, so amazon got them. Vokshod is vintage tube, so only tube stores (ebay or else) got them. Try googling for other tube stores. 

  Try the Vokshod or Voskhod. Despite being cheap, it got decent sound. Genalex gold lion also an option if you want fuller mid. 

  I see your point. And the brands do tend to not post enough information on the products. I mean, like if a headphone is rated at 64 ohms, well at what frequency? Usually it's measured at 1kHz, but because it's not really stated, they could claim, 'hey I never said that it's 64 ohms at 1kHz'...

  Not complaining about that one particular tube. I deemed that as a realistic and logical risk, that it can be broken along its way half the globe (Ukraine to Asia) and 1,5 month shipping time.   I'm also aware of ebay's protection. I think it was either keep the stuff and get partial...

  What I meant was that because the only viable option for me to get tubes is from ebay, there are big risks involved, even before the tube reach my hands.   For starter, the seller might be lying (not scamming) about the tube. For example, he/she posts good measurements of a tube, but send...

  Yea that kinda bugged me too. I mean, they (the brands) post all this measurement, but who's to say that they're not BS-ing? People like Tyler can double check with their exotic measuring equipment but most end users like me would just have to take their words for it, and probably got scammed...

  This is an example of a case where a DMM is a lifesaver (or rather sanity saver :) )   Use a DMM to test the closed loop between the TRS plug and the IEM connector's pins of the original cabling. Signal always +, ground always -. If it's inverted, I think it will still sound, but...

  Tubes are very fragile thing.If you buy used tubes, you don't know how much lifespan they have left.    Even new tubes are fragile. I had this brand new Genalex Gold Lion. 3 foot drop, and it's wrecked. No glass fractures, no loose connections visible inside, still wrecked....   An ideal...

  Powerful is not the same as good sounding. The T1's headphone amp part is actually a simple CMOY, if I'm not mistaken. It will surely do the job (of amplifying), but yeah, just standard stuff.      Strange. Theoretically it should be the same, because the decoding is done by the T1...

Oh, also a word of caution to fellow HE-400 owners (and maybe other hifiman models, as they're similar in design).   You know the hinges part between the headband and the yokes, right? The ones covered with blue, round cups with 'hifiman' markings on them? Well, the headband is metal, the...

  I don't know if it's been mentioned or not before (not fancy flipping through 1300+ of pages :p ), but HE-400 is what I call 'classic planar', meaning it's both low impedance and low efficiency, which is actually a 'nightmare' for small/portable amps. Low efficiency means it need more power...

Hiya all, found this particular topic through google. I have been to other headfi topics, but this is the 1st time (I think) I posted here :)   Well, anyway, read some of the posts/questions about the pads, and thought I'd share my personal experiences.    - the standard all pleather pad...

  Do you need real gold plated, or just gold color?   I got this cable from a local brick and mortar shop. It's copper, but kinda gold color:     I don't think the shop sells worldwide, but I found a similar (or better) one in ebay, in the past. The keyword was 'twisted copper wire' or...
