Hello LD crew. Thinking about pulling the trigger on a set of hifiman he560 cans, but wondering about compatabity with the LD mk iii. I've currently got some C3G's and 6SN7's in there right now, but being that the 560's are low impedance cans, I know they won't like the 6SN7's. I'd originally purchased and rolled my mk iii because I was thinking of going the Senn HD 800 route, but have since been semi redirected to the hifiman cans. My endgame amp will be a WA22, but I'm a year away from that still. Anyone have any insight into this? Thanks

Hi Michael, three ways to go with the Hifiman and beyond 6H30P/6N6P-IR power tubes: 1) 6080/6AS7G + power supply, 2) 5687 with adapter, 3) audiophile resistor cable and 6SN7.

Thanks so much. I'll poke around the web and see what is easiest. Sounds like it might be that audiophile cable with the 6sn7...

Edit: actually I think I have some 5687 and adapters already, so that might be my ticket. Thanks

Are there any downsides to using audiophile resister cables?

Yes, your wallet is much lighter...

I seem to remember that you built an impedance adapter to allow the use of low-Z headphones with your LD?  Granting that pre-built cables might be costly, practically speaking, is there a downside to using an impedance adapter to allow the use of low Z headphones with OTL amps?

Sorry I was thinking of something else.. Yes the little impedance adapter does cut the volume a bit but you just turn it up a little more. For my Low Z headphones it did remove the hum I was experiencing.
 
I was thinking about this bit of Snake Oil here...

I've used a impedance adapter with low Z cans with good results. My goal was to remove hum from the Lorenz c3g's, and it did. Not needed with the Siemens c3gs's though. Also I dont experience any distortion using 6sn7's with either my HE400i or the W1000X

You guys rock. Thanks a ton. Is there an impedance adapter you guys can recommend?

If you are handy with DIY, you can build your own. This one has a pair of 150Ω resistors in series with each chanel.

Any solution on the market? I would like to use my fidelio x2 with little dot, for now sound is very bad...

All Siemens branded ones seems to have gold pins.
 
I have several Siemens branded C3g tubes with pins that are not gold plated.

I use this http://www.ebay.com/itm/300453295797?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT
I got the 150ohm and the 300ohm version and the only difference between the two is that I have to turn the volume up further with the 300ohm adapter.

C3G questions.
 
So, I got my new adapter version made, using the NOS Amphenol sockets.  The sockets themselves are a lot nicer engaging the C3G pins, but I'll tell you what, soldering to the terminals was a beotch...by comparison, the Chinese "gold" spades took solder like a champ.  
 
Anyway, the issue that I thought was the cheapo Chinese sockets, seems like maybe it is one of the C3Gs after all.  (1) tubes seems to have a short, of sorts...needs to be messed with/sittting just right.   Also, I noticed it was picking up radio signals today!?
 
Any ideas/input???
 
Did you guys note the german C3G auction, that Mordy pointed out, ending at 300+ Euros...will end up being a good score for someone.

Epic. Was having trouble finding anything on the web. Probably should have just used the headfi search engine. Thanks bru.
