Hi
I have a AKG K340 headphone. I drive its with a heavly modded T-am (ALPS pot, Black gate capacitors, new case); obviously I've modified signal cable (now mono and not ever stereo). T-amp is suitable for listening of Internet Radio but not for music. The question: Could C-Moy BB of JDS lab be suitable amplifier for this high impedance headphone?
thank you

no you need a very power amp, coupled with a dedicated source component. ie a dac of some sort and a headphone amp like a DV 337. They are hard to drive and a lot of people struggle building a system around them because of their intolerance of low end components.

Depends on the specs an output power/impedance of those amps. You might want to try the S·Amp or the Presonus HP4. Both are made for lower impedance cans, and the presonus one can even act as a pre-amp for speakers.

I owned both stock and modded K340s and no portable amp will drive them even semi-well, and many desktop amps struggle. A good budget choice is the Darkvoice 336, which I believe can still be purchased for around $300 or less. I also liked the 340s with a Heed CanAmp, which is a bit pricier, but you might be able to find one used, saving some money. Though I've no experience in this area, I believe some folks awhile back got lucky with using the headphone out of some old integrated amps or receivers they picked up for $100 in thrift stores, but that's really hit or miss.

The Darkvoice amps seem to have the best reputation for K340s I've seen - I still want to get one when I have the money to spare, I think my PPX3 just doesn't have enough power to drive them.

re: k340

I started using mine with a Corda Prehead MkII and often found myself with the volume knob at 3:00 or more................more oomph needed......though I could have tried upping the gain on the Prehead.

So, got a Ming Da MC 84c07, and put some NOS tubes into it (orig. Mullard EL84, an Amperex 6HU6, and a pair of Raytheon 5751/winemill). This works wonderfully with k340 and also the best I heard with beyer dt990/600.

Less will definitely NOT work.

I used K340 with Aspen 823 OTL and the match was perfect, plenty of power as well...
