I finally just picked up a pair of EML 300b's, Frank I digs them, and a pair of RCA 5U4G's for my WA5!  Finally upgrading my Shuguang 300b-98's.  Man, this hobby is expensive.  I didn't tell my wife how much I spent on the tubes she would be mad! Loved Dubstep Girl's rectifier shootout. Didn't...

Glad to know the WA5 can do the deep bass.  I am looking to upgrade from the HD 650's to a pair of LCD 2/3 or a pair of Hifiman HE-6.  I have seen people lovin' the K1000 jack for the for the HE-6's.  Like Dubstep Girl I listen to trance/electronic music and need some good deep bass performance...

Anyone ever buy from www.thetubeco.com? The prices are cheaper than The Tube Depot or the Tube Store, but something tells me that we may be getting the domestic "seconds" not meant for export. 

I just purchased a pair of LCD-2's, coming in a few days.  Anyone try their's on a woo wa5?  I hear they like a lot of juice, anyone try them in the K1000 jack?

Just purchased a pair of Shuguang 300bc's for my WA5, and a pair of "Preferred Series" 247's for the rectifiers (although I am not expecting a major change with the 247's).  I'll let ya'll know if they are any good, as I have not seen anyone rate these tubes yet.  I was gonna buy the Psvane...

Quote: Congratulations on your upcoming addition to your system, Frank!  I have had my Wa5 for just 3 months now, it is the best headphone sound I have ever heard.   It has finally settled in (Blackgates and v-caps took a while to open).  I still have the stock tubs, although I am...

Quote: I have the stock tube combination in my wa5, hopefully this is the reason the system sounds thin.  Nobody seems to like the Ultrasone brand with wa5, I agree.   I am about to pull the trigger on the EML 300b or the Sophia mesh 300b power tubes and the EML mesh 5u4g or the Sophia 247b...

Quote: Thanks!  Wow, the EAT's are expensive! I have never seen anyone, in all my hours surfing head-fi rate the Genalex golden Lion 300b's in the wa5, any comments?.  They are available on TubeDepot for $330.  My headphones are the Sennie HD 650's, which I think they are a little thin and...

Whew!  Buring in an amp for 500 hours is a long time, darned black gate caps!  This thing is quite an upgrade from my ASL mg-head OTL III.  Anyhow, looking for tube recommendations.  After combing head-fi, I have come up with a short list.  Man, Head-fi is a great resource.  I could use a little...

Quote:   Well did a little research online.  I read that many diy'ers have had trouble with the JJ 5ar4/gz34, arcing then failing.  I pray that the Shuguang was just ripe to fail with loose parts, from the start, and the JJ's, despite being pulled from working gear (a Primaluna prologue 3...

Grrrr!  My NEW wa-5 is now broken!  One day, the right rectifier tube, the stock Shuguang 247b, sparked upon startup, but thereafter worked fine, but developed a slight rattle during operation.  I think I may have not waited long enough after shut down before rebooting in the speaker selection...

Finally hook up my WA-5 to an old pair of Acoustic Research HO 308 bookshelf speakers.     The specs are as follows: 1” Aerofoam Dome Tweeter, 5 1/4” Midrange Driver. 8” Long Throw Woofer. Frequency Response: 40Hz – 20KHz +/- 2 db. Sensitivity: 92 db @ 2.83 Volts/Meter. Nominal Impedance: 8...

Quote: Great responses Head-fi'ers to my question  .  I had done some research on v-caps, they need up to 400(!) hours, so my current 150 hours is not even half way there.  I will probably need to upgrade the tubes.  The ASL mg-head OTL did need tube rolling to maximize it, although the...

Hi wooians, I had recently purchased a WA-5 with all the capacitor trimmings with the stock tubes (shuguang 300b-98, shuguang 247a, ge 6sn7).  Upon first firing it up, I had great expectations, as it was better than my Antique Sound Lab MG-head Mk III without any break in and, of course, the...

I just received my new wa-5, with capacitor upgrade, tonight!  Totally stoked!  I can't believe I just spent over $4,000 on a headphone amp.  People that I told about the amp think I'm stupid! Pictures don't do it justice.  The Woo is replacing my Antique Sound Lab MG head OTL mk III. Hooked it...
