I just bought these to replace the EL34 power tubes in my Decware Zen Triode Integrated Amp. After about 40 minutes of warm up and break-in, I could immediately tell a difference between the EL34s with tighter bass, more texture in the mids, and smoother highs. The tone became much more "wet" with certain sounds taking on more palpability and "in the room with me" realism. It also seemed to open up new layers of my standard tracks by bringing some of the instruments more to the front without washing anything else out. So far I'm extremely happy.
Shipping was fast, the product was securely nestled in the box, and the product looks and sounds great.
