I'm interested in the WA2.
I like the idea that it can be used as a preamp.
But when I mailed Woo, they don't offer any other upgrades then tubes anymore...
...is the WA2 great as it is? (I was quiet interested in the stepped volume pot. and maybe a power supply upgrade if that was available.)
What do you guys think? = )
I use my WA2 as a preamp at least as much as a headphone amp. I am very pleased with it's performance in both roles. Mine is stock except for second set of preout (to send signal to subwoofer) and a custom pre-out switch. I've not heard the other volume control options, but the current one does not leave me wanting. I understand current production units now have a standard switch to turn off the pre-out.
I'm still waiting for mine - Hint-hint, Jack :^)
When using the WA2 as a headphone amp, have you ever used an external preamp (separate component from stereo or stand alone unit) out into the Woo?
Not yet. I went through a phase where I was listening to a vintage Marantz Model 3800 as my pre-amp and I almost used the Woo just for HP. But, after the initial novelty wore off, I put the Woo back in the system as only pre-amp.
