Got my Tung Sol 6SJ7GT mesh plate tubes in. Pre burn in, they seemed to add a bit more smoothness and definition to the high end than the stock Chinese tubes. The RCA 6AS7G gave more smoothness overall than the stock Chinese tubes but with the same overall sound profile. I think the thicker sound of the RCAs (probably described by most as being a bit more bass/mid heavy, which I like) with the more balanced, maybe even higher frequency emphasis of the Tung Sol really makes for a well balanced combination with emphasis in all the right areas and in all the right ways. Granted these are my first two tubes so there may be better, but for now I haven't heard it =D

What are the best replacement tubes for darkvoice 337 ever produced? thank you

 

[Skylab]

For the driver tubes, I think the Tung- Sol 6SJ7GT with the mesh shield are the best by far. As for the power tubes, I liked the GEC 6AS7G/A1834 and the Tung-Sol 5998 best.

Those GECs are almost impossible to source.

 

[Skylab]

Indeed, sadly. I see them on EBay from time to time, but they are pretty rare. The 5998 is getting harder to get too, but there are more of them than the GEC, for sure.

Dear Darkvoice 337 owners:
 
I have some very nice 6SJ7GT tubes I want to give away free.  Please PM me if interested.  Thanks.

Agreed I own a Darkvoice 337 and it is pretty awesome However just wanted to ask how do the Denon D2000s/D5000s when paired up with the Darkvoice? Compared to the DT990s 250ohms version which would have a better sound signature ( in regards to bass ). I would prefer more bass extension, sort of like the bass will reverberate around your head, but not so much that it overshadows the vocals or covers detail. Anyone heard this pairing before and could tell me his/her experiences?

 

[pataburd]

From my experience, the 337 DOES NOT drive the Denons well--at all.  The D5000 sounded very brittle, edgy and closed in with the 337.  This was the ultimate reason for my selling the Darkvoice.
 
A good--even a half-way decent--solid state amp really makes the Denons shine, though.    

 

[voodoohao]

oh damn, was hoping that the Denons synergize well with the Darkvoice. What if a decent DAC was added to the mix?

Pataburd is right, and a DAC isn't going to help.  The 337 is simply not technically a good match for low impedance dynamic-driver headphones like the Denons.  You need a transformer coupled tube amp to drive low impedance headphones like that, generally speaking.

 

[Aanta]

I concur with what Skylab and what pataburd said.  These headphone amps should not be mated with any low impedance cans at all.
 
I went the other way and parted from the 701's and got myself the 250 ohm AKG 601's and the Darkvoice now perform as good as I could ever have expected.

 

[fhuang]

i didn't like my 337 with low impedance cans.  from hfi780 to k501 to gs1000i.  hf2 sound ok though.  by the way k601 is not 250 ohm and i didn't like my k601 with 337

Hmmm is there any headphones with similar bass qualities to the D5000 and at roughly the same prices? Which would pair well with the Darkvoice. Currently I'm using DT990s and I feel that although the bass impact is excellent it is more of a hard hitting kind of bass, rather than one that reverberates (vibrates?) around your head. I guess I would call it having a more punchy bass, while I've auditioned the D2000s and feel that they have a deeper bass extension, and the D5000s apparently trumps them in bass from what I've read. However I'm unable to audition the Denons with a Darkvoice amp cause the shop I go to does not stock Darkvoices, thus I would not be able to hear what the Denons sound like until I actually buy them, which is a bit risky. So hope you guys can help me out. My emphasis would not only be on music but on gaming and movie watching as well, so would like a set of cans with excellent immersion and good soundstage as well.
