Yes you're right, it increased the volume but not a huge amount. No harmful effects to the sound quality.

So was this the only sound difference (higher volume) that you heard with the high impedance?

From what I've also briefly read, if you don't (match) use the low impedance with low impedance headphones, you are over working the damping of the drivers for no reason, an there is less driver control…this is why I don't do this, or never even tried it. Also on the other hand there are debates about this, so I don't want to start one... but this is what I understood and stuck with it.

I have a 1960's Mullard GZ34 f31 X8X, and its a nice sounding tube, you should enjoy it!

I will switch it back today and see if there is any difference in the sound. Looking forward to getting the Mullard! Thanks for your insight.

try a different set of RCA cables on the amp.  A friend of mine had the same issue with his WA7 and sent it back to the mothership to find out it was his RCA cables.

For safety before you open the amp, leave the amp plugged in while power's off so that all capacitors can be discharged.  I usually leave it for ~30 min for the caps to discharge.      

Thanks for the advice! I ended up disconnecting everything and swapping out the tubes. After I plugged everything back in, voila! Amp sounded great. Very happy especially since I'll be going to RSD this weekend and have a few serious listening sessions coming up.

I switched it back to the low impedance setting and I hear no real difference between the two. The increased volume is negligible and of no benefit. I just have to turn the dial a little further. For me the dial at the 12 o'clock position intensely loud. Some songs just need to be blasted!

yeah, im still around but i'm much less active, mostly responding to the few threads i still like and PM's asking for advice, thats about it.

The last 34 metals I tracked went for £60 and £90.

the secret to buying tubes is to buy them in the continent they were made in!

Ahh, very nice!

Hope you enjoy them with the S/P. Is the base brass…or anodized metal?

Thanks joseph, it looks like brass or then again I've been wrong before.

Well what ever they are be sure too enjoy their sound, and let us know what you think of the 3 Sophia's together. I have the S/P but I use Sylvania 6SN7WGTA's, and out of all my rectifier/driver tube combos this gives me the nicest sound-stage and depth…but the Sophia's 6SN7's supposedly give even more!
