Look into the Mullard M8100 if you're thinking about a tube upgrade.

Yes from everything I have read those are very nice tubes. And they came with my USA version MK IV SE. I now have about 70 hours on it now and the sound keeps getting better and better.

btw for anybody buying a new tube amp from China make sure that who you are buying the amp from is a authorized dealer. My MK IV SE comes with a 2 year warranty but only if it is bought from a authorized dealer. I got my from David at little tube so in my case np.

Since this is a thread for DV332, I think I will post it here too.

Anyone who happen to own a "new" version of HD650 + Equinox cable , and the DV332, please tell me what you think about the synergy.

Referring to this thread, I found that my new version does not go so well with Equinox. With Equinox and DV332 (Svets and LM 403B's) I find that the phones sound too harsh and I can feel that bass is less impact and more muffled compared to my old version.

And more surprisingly, the phones sounded better when I removed the Equinox and put in a stock cable. With the new version, I clearly prefer that cheapo 12$ cable over a >300$ Equinox. I don't know what is to be blamed, the cable, the phones, the amp, or even myself.

Since many of us here own HD650, I believe someone in this thread would own a new version and the Equinox. Please let me know what you think.

I have the newer version 650s and the exact same tubage your using, and I found the Equinox opened the whole stage from floor to ceiling and wall to wall. I had been using the Cardas cable I got when I purchased the Senns, having put the OEm cable on my 600s. Technically, I know I can't compare SAA to stock Senn cable, but I know that Equinox ended any further tweaks or tube rolling...

Yeah bOUddha, I too can notice an improvement in soundstage, but I really can't stand those ear-piercing treble (especially sibilance), and the lack of quality bass (not quantity, of course).

Maybe I need to see if something went wrong in my setup.

 

[kendal3334]

any idea about 332 driving QP450?
i think tube amps would be fine for this phone, just wanna know if anyone used to try it

Doesn't sound like my rig in the slightest. I don't know that I would even investigate any options to improve what I'm hearing, and my source is mostly a Sony ST-J75 FM tuner (recently refurbed by Terry Dewickt). Mahvelous stuff...

What source are you using? Could there be an impedance mismatch? I have a couple of CD players that sound rough when played through the DV (so I don't).

My source are Rotel RCD-06 and Arcam DiVA CD73, and sometimes iPod Nano 3G. I don't know if it's the impedance but I don't have this problem at all with my old pair.

Additionally, yesterday I tried connecting the new phones with my NAD C372 stereo integrated amp, and the problem still persisted, so I highly suspect it's my headphone itself.

I just got a Darkvoice 332 amp, which I had taken off of Gradofan's hands, and wow, it's even better than I had imagined. Paired with my Diyeden SVDAC04 DAC and newly arrived HD650's, this is a killer combination.

Yeah...

And... if you're (any member) one of those with a DV332, who thinks you can do much better by upgrading to a more expensive amp... think again, before you sell your DV332!

You will not find an amp, that significantly betters it at 3 to 4 times the price - so don't bother trying.

You'll only regret you did.

Also... I should note... even though the tube selection for the DV332 is limited... the tubes that are available for the DV332 produce some of the best sound available from any tubes - so don't be lured into thinking other tubes will sound much better. Somehow the special combination / synergy between the Solen caps, with the tubes it uses, produce an exceptionally good sound quality.

By the way - DV made a big mistake by discontinuing this amp - they should have just upgraded the POT, the tube sockets, the RCA connections, the power supply, and the fuse, and left it in the their product lines. Replacing it with the DV3322 with wholly different components may well be "ruining a good thing" - perhaps they should have "left well enough alone." I doubt very much the DV3322 will sound as good, or better.

Maybe we will get lucky, and the 3322 will actually be just as good or better....
If so, I'm already thinking about one....

AudiophileChina reported to me the TingFeng is not identical in all respects to the DV332, and does not share all its parts. I think I recall it uses different caps, or resistors, or both, as follows:

Resistors: Dale (not the big military grade units of the DV332, which were proven)
Caps: Phillips Beyschlag Centralab (not the Solen, which were proven)
Diodes: Fuji
POT: ALPS-27 (may be same, might be better - should be Blue Velvet)
RCAS: CMC816u
Tubes: Same
Case: Appears to be lesser quality paint
Power: ~1 watt

I wouldn't buy one, unless it is identical, or with minor tweaks - you can't be certain it will sound as good, or will be as reliable.

Given it's lower price - I doubt it will.

If it is the "re-branded" DV332, they should just upgrade the POT, the tube sockets, the RCAs, the fuse, and possibly the resistors... and maintain the same high quality case - and the same, or slightly higher price. The original design and parts selection has a special synergy that is very difficult to improve upon - except through relatively minor tweaks.

They'd sell a lot of them, if they did. With lesser parts - I doubt they will, no matter what their price.

Gradofan its sounds like you are regretting you sale, You may be happier when your new amps arrive !!!!!!

 

[BigTony]

At the moment i'm regreting my purchase! My 332 developed a fault within a week, i spent 2 weeks fiddling changing valves, bending pins etc, and now its spent 2 weeks with an engineer who's still trying to find out the cause of the annoying sound.

Just my luck to get a dud.

[omegaman]

Hope you get it sorted Tony, That was one of my concerns when I bought the amp, China is a long way to send it back !!! but touch wood I've been problem free.
