Sophia Electric™ 12AX7 vs. Siemens 12AX7

Received date: June 9, 2015

Sophia 12AX7 compare to Siemens 12AX7

Bass definition is much better on Sophia

Midrange bloom is almost as good as the Siemens

Top End almost as good as the Siemens

Soundstage and tonality are equal on both tubes.

I am hoping as the tube breaks in that it will be as good as the Siemens 12AX7. Right now I have about 15 hours on to the tube. So far itís a good value compare to the Siemens 12AX7 considering it is about half the price. NOS Siemens are going for $175-$225.00 on eBay.
