Hifiman HE-6 with portable DAC and double portable amps?

post #1 of 6
Thread Starter 

Until recently I've been pushing a pair of HE-6's using a Cypherlabs Algorhythm Solo -dB, an Alo Audio Rx Mk3-B+,  and an iFi iTube. It sounded great! I move around alot, and bought a battery to power the iTube to be able to take the setup wherever I wanted.

 

I've just toasted the iTube by plugging it into a 220w socket, unfortunately. Any ideas on another way to be able to push the HE-6's on the go?

 

Is there another preamp like the iTube, but with an internal battery?

Could I use a second Rx Mk3-B+ to produce enough power? Perhaps my current Rx along with a Cypher Duet? Everything wired with balanced cables?

What other possibilities are there?

 

I'd much rather find a solution to portably amp the HE-6's, than invest in another set of over or in-ears or a desktop amp.

 

Thanks for any responses!

You could go with an iBasso Pb2, with about 2.5w with the balanced out and a nice form factor it's pretty damned powerful. It should do the trick. RSA audio also has some Balanced amps

 

I do actually own the HE 4, mine arrives today. I'll let you know how the Pb2 drives it 

 

seeing as the HE 4 is most likely among the headphones that are "about as" hard to drive as the HE 6

Thanks Mshenay! I'll look into that amp.

 

So can I run two amps after my DAC to get the power I'm looking for? Seeing as the Rx with Solo is pushing them adequately, could I pipe in a second Rx to be able to run the HE-6's well?

 

The iTube combined with the Rx and Solo really did the trick, it was really just too bulky to carry around with the extra battery.

 

This is a setup that I swap between a desktop computer, media player, and tablet PC, so I'm really trying to dodge investing in any desktop stuff.

 

I'm not getting the reverb I loved without the tube element in the setup anymore, though I'm not sure if that is because there is no tube anymore, or I just can't reach the volume I used to.

 

Even with the sound getting amped by the Rx and iTube, I still have to set Foobar on my desktop to a +20db volume setting to get the sound I'm looking for, and with this Crapple Ipod, I had to unlock the volume AND increase the volume further in iTunes just to almost get the volume I was looking for.

 

These headphones are MONSTERS! Had I know before I bought them, I probably wouldn't have. But now that I know how beautiful they sound, I don't want to let them go!

Yea they are nasty hard to drive, you need a lot of Voltage and current to run them, I 'm not sure double amping will increase the power... even with let's say 1000 mW in a second amp can't... output more than it's maxium rating is, you  may wind up with too much voltage and no current... I'd try and find your self as powerful an amp as you can that's the size you want!

If the iTube worked, there must be something else that can. I'm not currently in the U.S., so I'll have to stop by an audiophile store and give a lot of devices a go in a few months once I'm back. I can just go back to the iTube solution I suppose if I don't find anything.

 

I'll contact the iBasso folks and see what they can tell me.

 

Thanks for the advice! I just got into this hobby, so there's a lot I still don't know.

 

I would post a picture of the rig, but I'm still too new of a member!

I found a store with the Alo Continental tube amp available for audition! I'll let you know how things go! Fingers are crossed.
