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.\rSo far it\xe2\x80\x99s 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. Ray, New York |
