Kevin says this is the best-made Telefunken he has ever encountered, and the best-testing of all our tubes. Shockingly good, neutral and beautiful sounding.
The average of 60 reviews? Five stars! No other tube gets such consistent high ratings. "I don't recall the last time I spent this kind of money and was so happy with the results." "This tube is the best I have heard." "Immense soundstage."
Actually, let's focus on the three reviews out of 60 that weren't a full five stars. One customer gave them three stars because about two years and about 100 hours later, the tubes were noisy. Unfortunately, this happens now and then--even with well-testing tubes. Another three star was from a customer who compared them with much more expensive and rarer tubes. And the one four star was from a guy with a tone generator and oscilloscope. Need we say more?
