First of all fast delivery of goods purchased by DHL ( Germany to Athens Greece ). Very good packaging as well. The tubes replaced the Prima Luna original ones in my Prima Luna HP and are even better. Although the sound is a matter of taste, these tubes have better soundstage vs PL the sound is warm but without loosing details. Very good bass control. I have also purchased Siemens ECC82 from TAD out of couriosity. This a different case vs PL and TAD ones. Even better soundstage and detail, but not warm enough for my taste. With rock music are sometimes harsh.I enjoyed them a lot with piano music. These are my first impressions since both tubes need some break in period. I hope that my comments will be of help.
Fantastic tube. It replacement telefunken ecc802s and TAD is so much better. It`s like i get a new amplifier. Highly recommended A+++++. And excellent service. Thank you TAD
Weighty, solid, superbly crafted tube that replaced a chinese no-name in my pre-amp, driving class A SE amps.
Immediately apparent changes were a de-fogged, more spatially present and in your face sound.
More detailed yet smoother presentation.
Prior edginess on high frequencies has dissapeared.
Love it !
Oh...did I mention that these guys ship and deliver within 36hrs ?!?!
Will definitely shop again !
