Anyone knows the SQ of K3003LE? Coz I can't find any review on it ...except one in Chinese...Is it only available in Asia(for PRC people since they like gold so much)? I saw one today when I do shopping (I am from Hong Kong and K3003LE is everywhere) I wonder what's the difference between K3003...

to me...it sounds a lot better than the 6C45. I hear a more "tube like" sound with WE417a, with smoother treble and luscious mids.. still burning in though so the sound may change..

  OMG..I did it!!! I know that Jack did warn us "DO NOT use tubes that are not approved by Woo Audio."... I didn't listen...i know..I am a bad boy... but it all started because I got the wrong confirmation that 417A could be used for WA7.. First I did some research and realized that...

Justin... now looks like the US orders are fine, so when will you do the international orders? I can't wait to get mine! (I should be in the first batch.....am i?)

Good for you guys! i still haven't received the shipping confirmation...

Damn!! Yours look nicer without that tiny square!!

Edit: Jack replied me already

anyone know if 417a will work on WA7? coz these tubes are easier to find..   I did some research and found this:     WE437A 6.3 0.45 7.0 250 　 ± 50 11.1 1.0 3.8 　 140 180 -2 -3 29 25 950 980 43000 42000 41 41...

I don't think batteries are included...

Quote: I am thinking if i should purchase a pair of WE437 .. just to see if the sound can improve..   but the price tag...scared the shxx out of me...

Anyone know if there is any substitute for 6C45 that WA7 is using? I am using the WA7 with Hifiman 500 and found that the sound is a little bit lack of warmth... wanna change the tubes if possible...

Quote: I just ordered a WA7 and it so happened that the dealer has extra stock and I got to pick mine up today! so lucky! I tried it at the local dealer before I made the purchase. Not only does this small cube look great, but also sounds great with my HE-500 + cardas clear headphone...

Guys, I have a few USB cables at home and I did try it with my DAC. There is a sound difference.   I found that USB cables with a "filter" affect the sound most, and I prefer removing the filter for better sound quality. Don't believe me..try it yourself!   Also, I found that the good...

got a HE-400 from Justin! It was great to have international free shipping and the phone got here within 7 days!! Amazing purchase experience and I highly recommend buying headphones from him!!
