The Woo Audio 2
In this morning, I bid another a few Tungsol 5998s in eBay. I found they are all "TOP GETTER" type 5998 However, I realize most WE 421a are "CLEAR TOP and BOTTOM GETTER" type, and I hardly found this type of 5998 So I don't think you can get the exactly same sound of we421a from Tungsol...- herroyuihk

Woo Audio 2 rectifiers tube rolling
Try Mullard NOS square getter EZ80 Jack told me that many customers feel this tube has best synergy to Wa2. Telefunken EZ80 couldn't deliver smooth sound when combining with Wa2. Sometimes people substitute EZ80 with EZ81 but I think its sound is too laid back in Wa2. However, there are...- herroyuihk

Hello every woo user I have rolled tons of tubes combination... Sadly speaking! I have not bought Gold lion U709 yet.... But the best sounding Rectifier is 60~70s round getter Mullard EZ81.... (Square getter mullard EZ81 or 80 is very slow and lacking dynamic??) The followings are my...- herroyuihk

Woo WA2 Tube Rolling Recommendations
I found Rectifier is also very important. Telefunken EZ80 has tight bass, but it is too exciting On the contrary Mullard EZ80 square getter is too soft. In WA2, We need to combine three type3 tube into a harmonious integrity, so rectifier may break this balance Jack tell me Wa2 can also use...- herroyuihk

Emission Labs 5U4G Mesh VS 274B Mesh
Don't you concern WE 274B? I think this it is worthwhile to use this tube in this amp For We6SE, you couldn't use a $1000tube But for Wa22, you can use a $1000tube in $2000amp This is a suitable combination- herroyuihk

Power cord for Woo Audio amps??
I just received my Wa2 for a week. But in this time, I like to pair pure silver powercable with this amp. Because its sound is very very tubey, silver cable can make him more balance. However, after it has been burned in or I rolled its tubes, I think that all situation will change...- herroyuihk

Woo Audio WA2 vs RSA The Raptor
I have used Raptor for two years, and roll so much tubes. I don't think it absolutely belongs to SS sound. It depends on your headphone, and I like it to pair with my HD650/. I planned to buy WA2 Maxxed to pair with Grado's headphone. In this case, my situation is different to you. But I...- herroyuihk

Hello Have everyone try WE421a in Wa2? If I want to get WE-like sound, Is this a right combo I can get this sound? PS. I know WA5 + W300B may be a more right choice. This combo is very ~~~very expensive for me. I could afford them right now.- herroyuihk
