does anyone know  who in USA can do repair work modifications on darkvoice 337 mine is doing crazy stuff

I'm  a little curious as to what head-fiers find more important.   Alright let's put it like this:   More on headphones = Your most expensive pair of headphones   More on source = Your most expensive DAC combo   So if you own 10 pairs of 100 dollar headphones, but have a 300 dollar DAC +...

I have a Darkvoice 337 and the dual volume knobs are pretty annoying. Anyone know any mods such as installing stepped attenuators?

I have a Darkvoice 337 for sale that I'm not using, and I just thought of using it as a preamp for my stereo, since it has preamp outputs. My setup is a JVC R-X500 1980s computer controlled stereo receiver, and a set of Polk Audio Monitor 10s.   I just read a thread on this and trouble with...

Hey All,   So I'm thinking of getting a yaqin integrated amp or something similar.  I'm wondering what to do, or how to use my Darkvoice 337 as I see that most of these do not have a line out?  I mainly listen to my turntable, so I'm wondering if I can use the DV as a turntable preamp?  I...

I am looking to make an amp upgrade for my various low impedance (current hungry) cans. The unfortunate truth of it all is that most OTL circuits just can't do anything below ~200 ohms.   Hours upon hours scouring through all the Skylab reviews and impressions have led me to these 3, and I...

If this thread already exists elsewhere, please point me in the proper direction (and I'll close this one). Otherwise, I thought it might be worthwhile to consolidate tube-rolling related discussion(s) on one, dedicated thread. : ) The 337 arrived for me just yesterday, having been shipped...

Hello, I am newbie at hi-fi world. Now i have Sennheiser HD 555 and its borring for me. I am ready to change for something new, I listen music at home and i need open headphones. For new head gear( Headphones, Amp, Dac) i can spend 1500-1600$ Max. Usually i listening Pop (90-2012years), Rock, I...

I just picked up some HD650's from Amazon and need an amp.   I know there are like six hundred and fifty billion threads about the HD650 and amps on here, and I think I've done a lot of digging and reading, but I keep getting confused about some things.   I'm looking to stay at or around...

I purchased a Darkvoice 3322 paired with my upgraded Zero dac and HD650 phones a while back and have been listening to my system with great enjoyment. Now, "upgratis" has set in. After looking through the forums, I see amp/dac pairing is very important rather than the quality of the individual...

In some ways, it has never been easier to buy a headphone amp: unlike years ago, there is no shortage of them on the market, with a bewildering number of different brands and designs available. This “bewildering number,” however, turns the choice of which new amp to buy into a difficult and time...

I'm looking for a good tube amp below $1000 and dont mind both balanced and single ended. Rather not get anything from woo audio though. Currently have a burson 160d. Will intend to use the amp with the Audeze LCD 2s, Hifima He5-le and Akg k701s. Am currently considering the Littledot mk6+ and...

Hey all, been lurking on this forum for almost a year now, but finally decided to join the community.  So here are some of the gear I have right now.   Desktop Setup Source:  HTR Music Streamer II+ USB DAC Amp:  Little Dot MkIII with M8100/CV4010 upgraded driver tubes, a pair of Voshod...

Hi, i recently got myself a Darkvoice 337, and im wondering what to upgrade next.... currently my setup is   PC(Coaxial S/PDIF) --> Maverick Audio Tubemagic D1 (RCA) --> Darkvoice 337 --> Sennheiser HD650   The S/PDIF I'm using are actually just the yellow video RCA cable, and im using...

I posted this review over on the LD site a few weeks ago and several folks have asked me to post it here as well. This review takes you from ordering through burn-in and tube rolling. You will see time breaks, these are from additional postings that updated the review as I went along. I freely...

I'm seriously considering a tube amp, but I'm having a difficult time finding one that can properly drive a 25 ohm headphone (D2000/D5000). Any suggestions? Thanks.

I own one of these amps, and it's nice. I've never actually heard it shine since I was stuck on Beyer DT770 Pro 80s, which focus on bass. The dual volume knobs have AWAYS aggravated me somewhat and just recently they have driven me crazy! Is there a way to balance the volume knobs perfectly, so...

I have a Darkvoice 337 with dual volume knobs (dual monaural), but it seems that no matter what I can't seem to balance the left and right. It seems that the right side is harder to drive than the left, because one twitch on the left equals 9 to 11 oclock on the right. Is it just me, or the amp...

I'm considering pulling the trigger on a pair of headphones, only the person selling them says that one ear sounds quieter than the other.   Is it possible to balance this out via software? How well does that work? Do unmatched volume levels point toward a malfunctioning driver?   in...

I currently have the DT770/80 Pros and they suck at rock and metal IMO, but I will darth them for hip hop. What are some good cans for rock for this amp? I know Grados are great for rock/metal, but do they pair well with the DV 337 well? If so, then I plan on getting the 325i's STAT.

hey guys, recently eyeing a Darkvoice 337, listen to a wide range of genres, any recommendations for a good all rounder <$500? P.S. i have 2 grados but figured there will probably be impedance mismatch.

Hey guys, some weeks i finally decided to get a tube amp, the Darkvoice 337, but right now my only headphones are a MS1000i and a AKG K240M that i'm selling soon, any recommendations for a good headphone <SGD500? i listen to most genres, but mostly classical and rock.    P.S. i'm getting a...

Hi, it seems like my tubes for the 337se are dead. What kind of tubes can be used for this amp? Thanks in advance.
