Fidelity182: The WA7 overall, with the tube upgrade, but some of that depends on the headphones and the music. The more demanding the headphones and the more detailed the music the more apparent the differences. The PanAm is still very good with the Gateway and better than stock tubes and only a bit behind with a lot of music.

I got mine for the pre-order price, and haven't received anything of that sort yet...

 

Mine is an original version too and I just put pieces of sticky silicon that sounded the stick-on feet from something else on the corners rather than bug Jack about it.

 

However, in your case I'd contact Woo Audio and ask them about it.

Hi, 

 

Thanks again for the update, I am very new to this forum, but find it pretty interesting, lots of information.

 

The PanAmp sounds very warm and bold indeed, for its price at $699/- in Singapore. 

Unfortunately if you make a AB comparison with the Studio Six, immediately you will notice the difference.

Both has its characteristic, again depend on your budget and taste again :happy_face1:

Nope, no chance to audit the WA7 yet.:happy_face1:

Interesting review. :wink:

Just got the PanAm and LCD2,2 for Black Friday (15% off the Pan Am and 20% off the LCD, around $1250 total!) what a combo.  I was thinking of the WA7 but for less than half the price I went wight eh Pan Am.  Just rolled in some Mullard Tubes that many recommended and they sound awesome, great separation, staging and punch.  I am not sure how the WA7 could be much better but hope to check that out at a get-together. (sorry for the multiple posts, computer went crazy!!)

Secondly does the old theory of tubes clipping more gracefully the dynamic high peaks in the music still hold sway? I do not know if relatively low-power headphone amps are subject to power amp theory, but I thought may be they are.

Forget about clipping, that should not be happening, get an amp that has enough headroom. This is easy enough to do nowadays. The old theory is not old theory but soft tube clipping is for an electric guitarist not for someone trying to enjoy listening to music (playback). If you opt to buy a tube amp it's not for the purposes of clipping but for the sound of tubes, being even order harmonic distortion, not a lot of it, just a bit for warmth. Myself, I prefer the clean sound of Solid State, but that's a personal choice. I do have a small hybrid amp.

 

OK all those preliminary quotes are in preparation to ask you what is the theory of tube rolling is it just the even order harmonic distortion which StanD mentioned in my quote immediately above? Or is it also monkeying around with the total headphones frequency response delivered to your is? (Which I know can also affect soundstage.) Or is it some sort of coloration which camp beasts called distortion? Or what all you all think is the reasons tube rolling works?
