I usually find with these types of reviews they have never really had the great stuff, bottom line is they are often comparing ordinary against their previous junk valves on poor systems. If a system is poorly tuned, it is open to a valve with a niche performance characteristic, and it seems to work well and outperform the great tubes, but only on there own system. Experience has taught me to take most of these opinions with grain of salt. I have found in general if a tube sells for outrages money, it's a very good indication it is a good sounding valve.
