Off topic here. Everyone have a happy 4th of July!!!. I'm going to party my ass off. I hope everyone has a great day, and night! Enjoy people!

Both the Telefunken and Siemens E88CC will be on the clean/bright side of things, and of course, many Telefunken branded tubes are actually Siemens made (if they do not have the Diamond on the bottom then they are often Siemens-made).

Hi

It could be that the HD 800's still need more time (they have about 50hrs on them). I bought the WA2 second hand and I have more than 100 hrs on them so I don't think the WA2 is an issue.

I hope you are right about requiring more burn in as that will save me $$$$ but I suspect it will not be the case. However I am keeping an open mind.

Hey M,

Small world, hey?

I think it may indeed be an issue of headphone burn-in. I can only imagine that the large drivers of the HD800's may require a good 200-300 hours to fully flourish. I also suspect though it may be source-related. I could never get to enjoying the 840C's sound; so perhaps this may be something you are hearing given the 800's neutrality and ability to portray a sound true to the source? Have you tried it with a different source perhaps?

Cheers
X

Just a note - the GE 5998A are not the same tube as the Tung-Sol 5998. The GE 5998A is straight bottle, and has the same plate structure as the 6AS7, not the same as the T-S 5998. The two tubes can be used interchangeably, but the T-S 5998 sounds much better than the GE 5998A, IMHO.

The 5998A I have are straight bottles so I assume they are the GE 5998A. I have not tried any other tubes but I am waiting for a pair of Tung-Sol 421A's I bought from you (Skylab). Hopefully they sound better than the GE5998A's.

Hi X

Yes, very small world (I bought my WA2 from X). I really do hope that further burn in will result in the WA2/HD800 combination delivering to the HD800's full potential, but I am keeping an open mind at this stage.

I will be experimenting with other sources and amps shortly and will let you know if my feelings (that the WA2/HD800 combination may not have the greatest synergy) change.

Regards
M

Well, my opinion is that they will...but I look forward to your opinion

Hi M, looking forward to your findings with the hd800!
X, you sould your wa2?
Greetings, Anouk,

I'm just wondering if there is anyone else who use the Woo Audio 2 with low impedance headphones (like Grados, Denons, etc...). I'm worried about this audible hum that people are hearing with this amplifier.

 

[Anouk]

Hello, i had few problems with th epro900 wich is rather low impedance but also low sensitivity. i have more problems with the jvc dx1000.
Greetings, Anouk,

I love this place. I absolutely love this place. Here I carefully read what was then all 17 pages of this WA2 thread, and then placed an order with Jack Wu for a WA2 to run my upcoming JVC DX1000.

Now people are talking about hum issues.

Wha-wha-wha-wha-what hum issues? Especially with a DX1000, which is like 70 ohms, and a DT770 Pro 80.

Is this a problem, or just an outlier? Is it just a computer/USB issue? I thought the WA2 was dead silent.

I'm using an Aikido right now that a friend built, and it "breathes" and "sighs" like the Edmund Fitzgerald heading into a nor'easter. Like a lap cat purring. It makes tubes seem oddly human, these noises, but I'd prefer just the music, ma'am.

 

[Possede]

Hello Anouk, that isn't what I wanted to hear. I was set on getting a Woo Audio 2, but now I am holding back because of the issue you have experienced using the JVC DX1000s.

Are you sure it is definitely the amplifier, and not anything else in your chain? I will e-mail Jack, and see what he has to say about this. Reading other comments on Head-Fi the Woo Audio 2 is supposed to be dead silent, with a black background.

 

[greggf]

Yes, Anouk, anything that you can tell us about your noises, especially with the DX1000, please do!

I'm looking forward to multiple eargasms via the JVCs, and want them amped just right.............
