great help, thank youbeerchug.gif

of course.but i not put the new cable now.

i want to think well before about my headphones

The SMC connectors in the Hifiman headphone are the same used in RF application - 30 ohm.

what does this mean?sorry my ignorance frown.gif

It means that if you remove the connector (hardwire), the impedance will drop. But to measure the impedance of a headphone requires specialized and expensive equipment, which I doubt any cable vendor have in house.

 

So unless you/your vendor send a hardwired pair to somewhere with a Prism dScope for example, we will never know what the resistance of a hardwired pair is.

Great! So, the impedance does drop, making the cans easier to drive. This is what my dealer suggested, making it easier to drive with more options.

It isn't that hard to drive to begin with. One thing is that if an amplifier clips with the normal He-6, it will still clip with the hardwired 6 tongue_smile.gif

 

If anything, lowering the impedance makes the volume louder, but it strains the amp even more.

then, reasoning on the contrary, if an amp has no problems, we will act less on the pot?

It isn't that clear cut actually. The best explanation I can give without going in to lengthy technical debate is that if the amp has no problem with the He-6, yes it mostly will not have any problem with a hardwired one. On the other hand, if it clips/distorts with the normal He-6, it will still clip/distort (maybe even more) with a hardwired He-6.

 

Now the other thing to mention is the removal of the connectors. The main reason one wants to remove the connector is that best connector = no connector. Depends on the (resolving) level of your equipments, removing the connectors may change the sound, or make no difference.

 

The thing that people usually overlook is that changes =/= better, and the intended design may very well be the best performing ones. I remember back when I first started, I read about how the Dt990, and other high impedance headphones (hd600/650, dt880/770) are designed to IEC standards - which requires a 120 ohm output. I did commission some modification to  several headamps from 0 to 100 and 120 ohm. The results are underwhelming to say the least; bass is wooly, and the sound becomes "fuzzier". If that was the intended design, I would never buy any of them.

 

Back to the He-6, I do think there will be improvements with removing the connector, especially knowing Robert - as he will trace and replace the internal wiring as short as possible too. The only possible downside to that is you can no longer toy with various wires tongue_smile.gif. I'm thinking of trying speaker wires, although some of the larger bi-wire stuff may have too large capacitance and roll off the treble.

ALL that said, I've got iron to satisfy the '6'; never been my problem. Yet, hardwiring will open up more options. Further, I'm not interested in rolling cables - don't like the connectors (less is better sometimes) either. And in addition to his personal pair, he's cranked a good sample of them out with satisfaction.

 

In other words, I am sold. wink.gif

I still need to try out some wire types (silver/gold litz comes to mind). After that I'd hardwire the 6 too, not sure if I'm brave enough to trace wire as aggressively as Robert. Worst case I'd send them over to Toxic cables.

Also post pics of the Sansui beerchug.gif

Wait... you mean the same Sansui I'm trying to get my grubby little hands on?! dt880smile.png I'm at the classic repair shop - a few sales staff and the lone Tech repair person. With a backlog of electronics. And as they're tagging your vintage amp, you're asked "You want it back when?"

 

I set aside an ample amount of cash in advance to cover the unexpected. Have reached over and spent this cash twice already. If I'm not careful blink.gif...

 

I thought you may have already seen pix of my iron last moon... er, last month. Trust me, I'll be so excited, gonna shoot it all over again.
