Woo Audio WA22 as a preamp. Opinion wanted

    Hello.
    As my screen name implies I am new to the world of tubes. I am a new member of this forum as well. I have no headphones yet, but from what I see on this forum, Sennheiser HD800 or Beyerdynamic T1 should be on my short list. 
     
    Now, about the WA22 question; I have already exchanged a couple of emails with Jack, but never asked him this question; How will a WA22 perform as a preamp when using the balanced XLR outputs connected to my Rotel SS amp (RB1080) balanced XLR inputs. What I mean is this; I know that it will "work", but should I be concerned with the fact that the WA22 is a "headphone" amp? (whatever that means). I guess I'm getting hung up on definitions i.e. headphone amp vs. preamp/headphone amp .
     
    My source is a Slim Devices (now Logitech) network music player called the Tranporter. It will deliver 96/24 music to the preamp via its balanced XLR outputs.
     
    I am also looking at Ray Samuels balanced "Apache", which is a SS preamp/headphone amp. I think that I would like to get into tubes and tube rolling. by starting at the preamp level.
     
     
    Thanks in advance for any of your opinions (signature included to give an idea of my current system)

    WA22 CANNOT act as preamp as the balanced ports are for the inputs, like the RCA inputs.
     
    If you want to find the one act as input, try WA2.

    I think the OP is referring to the XLR headphone out and use it as preamp out.

    Yes, exactly. In fact, Jack said he could add two more XLR outs on the back panel. Again, I'm not talking about physical connections, I'm wondering about its suitabilty as a balanced preamp to feed my Rotel power amp.  It' already well known as a top balanced headphone amp.
     
    The discussion is about the "headphone" amp vs. "Pre/headphone" amp semantics.

    I don't think anyone tried it yet.  As long as Jack said it is OK, than it must be OK.  You just need to try it yourself.
     
    Using is as headphone amp, it is the best tube amp Ii ever heard.  I have not try all of the other top tier tube amps yet...

    Thanks for responding.

    Seamaster bought a custom WA22 from Jack, and it has a pre-amp section.  I'm so damn jealous of him, but I'm sure Jack would be able to modify mine one day for a decent fee.
     
    I'm actually curious as to how well it would power a pair of speakers.  I'd assume you couldn't power anything with an impedance lower than 8ohms.

    I saw that Seamaster had additional XLR outputs, Jack told me he would add them for me also. I assumed it was the "same" as the front XLR jacks. Are you saying that there is more to it than that. Once again I get hung up on those words...as you said "it has a preamp section"
     
  10. jc9394
    Probably not but only Jack and Seamaster can answer that question...

    Seamaster said that he uses his WA22 as a preamp too.
     
    Here's a photo of his WA22:

    Look at this photo makes me realize how badly I need to upgrade those puny capacitors!

    Thanks Audio Dude. I've seen Seamasters mods before and that's why I asked Jack what it would cost to add one set of XLR on the back. I have been assuming that the additional outputs are just that...and that no changes or additions were made to create a different "preamp" section. Once again I'm getting hung up on semantics. I see we are both MA residents! May I ask where?

    Does switching between two sources qualify as preamp use? Or have modifications been made to Seamaster's amp? Basically what I am wondering is if the outputs on the back are controlled by the potentiometer like the ones on the front, or if it is a true line level out.
