Does it give enough power to drive fluently the Beyer 880 (600Ohm) ?

 

[nonogolf]

I got it today , yes it can move it .

I use it with DT990 600Ohm.  It drives them well and sounds great.

Great amp, you bought well! I still have it and use it often.

Thank you, i feel very satisfied with the choice, i just wish it could get here faster

I hope this thread stays alive, as I'm preparing to order mine today...
 
I was wondering from anyone who already owns this amp, do the instructions list the class/family tubes which are compatible with the 3322? I've found a few suggestions for tubes in this thread, but I can't seem to find any list of compatible tubes. This would help, as I'd like to research and possibly order some different tubes before the amp gets here!

 
Thanks in advance!
 
EDIT: Actually read this info in the review, skimmed through it and missed the tube info the first time around. Thanks, Godkin

Hey guys..quick question...does it do well with a he-500..as mine is 50ohm impedance and 89db sensity..thanks for ur help as i cant find any info about this combo. He500 needs 1watts and as far i can see the 3322 delivers that right? Or do i have to do something with the powertubes..stronger ones? Advice? Thanks

Got my answer myself..it wont pair well with my he500....sound is very thin..and the tremble is extreme grainy..the 337 actually did..so i bought the 337...it sounds heavely with those phones

Can any 3322 owners comment on what driver tubes they are using and if there is a lot of noise on the amp? I have been through several different brands/pairings of 6J1/5654 tubes and there is always a humming sound in all my headphones, ranging from somewhat quiet to unbearable depending on the tubes.
 
I'm just trying to figure out if there is anything wrong with my amp, or if I'm just getting crap tubes...Thanks!

I have the 332S and have tried dozens of different combinations, I finally settled on the Voskhod 6j1 with Svetlana power tubes.
Sounds like you have a problem as the background should be silent.
I did get a buzz with a few tubes when they were new particularly RCA Command and Sylvania Gold Brand but it gradually faded to nothing as the tubes warmed up.
Do you use a parts cleaner on the pins and sockets ? Even a small speck of dust could cause the problem you describe.

I dont have a 3322 but i had some kind of same experience with my 337 the other week..
I had to pull the tubes out for transportation to a Meet ..and when i got home my svetlana's hummed and gave noise from my headphones...just when i thought my amp was broken..i by accident changed both the driver tubes and the powertubes from left to right and wiggled them a bit carefuly while in..and damn..all noise was gone..dont know if it was because of not connecting well to the base or the change from left to right..but until now..perfect clean sound...maybe u can try that also?

question..did u get ur tubes from one seller only? Is it a reputable one? Try vacuumtubes.net.. Or tubemaze..both good companies to get ur tubes from imho.

Thanks for the replies, guys. I have tried changing the power tubes and driver tubes in all different ways, and the hum just travels from the left to right channel. I've tried contacting the seller of the amp, but have heard nothing. They are based in China, of course. But here's the strange thing; I just got my brand new HD650 today from Sennheiser, and hooked up to the 3322, they are dead silent. Meanwhile, my K550's still hum and my K702's hum, only much quieter than the K550. So now I'm wondering if it's an impedance issue? Someone in another thread suggesting trying an impedance adapter, which I had never even heard of before.
 
I used some Deoxit on the tubes and tube sockets on the amp, but that didn't do anything. Next I will try and blow the whole thing out with compressed air this weekend. The tubes came from eBay, but most of the sellers had 100-99% positive feedback so I assume they are reputable. My RCA 5 star tubes are relatively quiet, but the Vokshod tubes I just received hum so loudly in one channel on the K550/702, I can't even use them

OMG..pls dont use compressed air inside ur tube amp..it can damage the sensitive inside..google around to see whats best to clean inside..i never do it..a amp specialist does it for me regurarely..

And i am sorry to hear the hum still occurs..but its weird it doesnt hum on the senheiser...am sorry i cant help u with that..try the tuberolling thread here on headfi..they are pros in any thingies that can occur with tube amps..

Ok, thanks for the heads up on the compressed air. I use the stuff regularly on my PC, but I suppose the amp would have more fragile connections. I'll give the guys at the tube rolling thread a shout. It's not a deal breaker for me, still a great amp, just slightly annoying when I can hear that hum between songs.
