REVIEW: DARKVOICE 3322 - Page 28

post #406 of 490
Has anyone bought the La Figaro 332S yet ?
post #407 of 490
Is DV 3322 an otl tube amp or transformer-coupled tube amp? I am thinking it for use with my k702 and I know these phones don't like otl amps. I can't figure DV 3322 belong which type of them from pictures. Yes, somebody says it's great with k70x but these are wery relative suggestions. Thinking of price and huge shipping costs, I have only one shot to find best solution. Btw I don't think ss amp which I already tryed with canamp. They drive k702 well but I realy miss tube sound which I taste before with Ld Mk2. Any advice?

The 3322 is an OTL design. Conventional wisdom says these amps are not great with low impedance cans, and I'm sure in most cases this is true. I've tried the 3322 with 32ohm SUPERLUX HD681s and it sounded fine, maybe not as good as the SENNHEISER HD650s but not as bad as I thought it would be.

I also have a YARLAND P100 with a transformer coupled output stage and impedance selector switch. Setting the switch to 32ohms, I plugged in the HD681s and the sound was pretty awful: the treble was ear-splitting sharp. The 3322, an OTL amp supposedly designed for high impedance headphones, was superior to an transformer coupled one with an impedance selector switch.

Who'd have thought that!

May be output type is not only effective think in this issue. Weird indeed

Bought the amp used, and it is my first tube amp... Maybe you can help me out!?

The tubes have

"6C19N-B"
"VIII 70"
*DIAMOND* "13"
*CIRCLE* "OTK 5"

and on the box

"Ia=93mA"
"S=7.7mA/V"

Looks like you have Svetlana power tubes - 6C19P which are 6S19P in English. You're option for this tube is a Ulyanov 6C19P. The Ulyanov is marked with an arrow. Other than that there is a Chinese variant. Everybody around here seems to think they are teh suck. I think they are decent.

Your other tube I think is a Russian variant on the 6AK5, 5654, 403B, EF96, CV4010 tubes. They are all the same type of tube but are the Western variants from a whole slew of manufacturers. Apparently, the Ericsson 403Bs and Western Electric 403Bs are the best of breed. The Mullard CV4010s are popular as well. I haven't listened to them yet. I'm still burning in my stock tubes on my La Figaro 332c so I won't comment on what is best. Your best bet is to try the different variants and see what you like best. That's what I plan on doing once I get about 100 hours on this amp.

Those marks on the tubes are standard on all Russian NOS tubes: just quality control checks, year of manufacture, etc. But you've the good tubes there - the 6C19N-B or in English 6S19P-V, which are the ruggedised, military spec verion of the 6C19N or 6S19P.

Check the logos on the tube: if it's a winged "C" then it's a SVETLANA made tube, if it an stylised arrow pointing upwards, it's a ULYANOVSK made tube.

Anyone using the 3322 with the JVC DX1000's? Any comments? I was originally looking at the DV 337 but it's way too big and heavy for me...

You do realise it's not a portable amp.

LOL I am just afraid that my small table might not be able to support the weight

I'd say it'd be good with the JVC DX1000s. The jury's still out on whether the 3322 and low impedance cans are the perfect match. Some say they're great, others not so good. I tried mine with a pair of 32ohm SUPERLUXs, and was pleasantly surprised by the sound: not as good as the high impedance HD650s, but better than I expected.
