The sound is loud and clear with a very nice sonic range. Not excessive in tops, mids, or bass, they are accurately described as well balanced. The sample tested had no audible microphonics and an average background noise level. Back to top Sovtek EL34WXT - Sovtek has come a long way with this tube since the EL34G. Construction has been improved greatly reducing mechanical noise. It seems as if the frequency response has been shifted toward the midrange band.
Harmonics are rich and fairly balanced but the high end can get a bit bright.
Great in a darker sounding amplifier. Back to top Svetlana EL34 - If you want one tube that will do anything the Svetlana is money well spent. The mids are smooth and the top end shimmers. Nice swirling harmonic content. The construction of the tube is outstanding and I feel it contributes to the overall performance.
