I want to buy a good tube headphone amp for my HD600, DT880 and T1. Considering the Crack OTL, or Darkvoice 337se or LD MK IV, or Woo Audio or......   Appreciate comments and opinions.   Thanks.   Andy

Just wanted to ask anything has tried these two amps before and could post their thoughts on them? Currently I've just splurged like crazy on a used set of MKVII+, Matrix Mini dac and a HD650, wanting to try a balanced setup. Initial impressions seem promising as the HD650s seem slightly more...

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...

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.

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.

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 and the dual volume knobs are pretty annoying. Anyone know any mods such as installing stepped attenuators?

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 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...

My 337se has problem with the R/H channel, volume became very lower even I turn to max. it does have noise too. after turn on the power for a while, left side is heating up but right side still is cold. anyone know anybody able to fix this Amp around SF east bay area. any help will be...

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...

I recently acquired this amp and I am very impressed.  I am thinking about tube rolling and any other mods . I've looked at some threads on here but I'm not sure if all recommendations for the standard model are applicable to the SE. Could anyone suggest what I might try without spending too...
