Quality is Always #1
Quality is Always #1

Our state-of-the-art process begins with selecting only the finest tubes from all over the world. We then subject them to the most rigorous testing procedures, which are conducted in demanding “real-world” applications. Only about 10% pass the test and are given the Bugera name and stamp of approval. The rest are recycled responsibly.

This highly labor-intensive process is an art we’ve mastered over many years. As a result, ours are the fi nest and most musical tubes you can buy – at any price!

A matched pair would have been a better purchase.
I bought of these for use in my vintage Conrad Johnson PV9 preamp. The first day the sounded thin. The second day the sound stage expanded and voices improved with greater warmth. With these 12AX7b tubes in place the PV9 sounds more solid state. I did notice the voices of the background singers sounded as separate singers. A matched pair would have been a better purchase.

Best Chinese 12AX7 tubes I have heard.
Tubes do take awhile to "run-in", and I haven't really given these tubes any time at all to do so. That being understood, and understanding that my listening was brief, 2 songs. Furthermore, it should be understood that, for instance, I spent something like $1,000 on parts for the crossovers in my speakers. I have upgraded every component in my system. Preliminaries finished, I'll proceed with my initial impressions. These are not bad, they do sound more solid state than tube though. That may translate as accurate, but if your using tubes, you want that tube magic. I have been using NOS Amperex tubes from Holland. These tubes do not have the, shall we say, sexy, for lack of a more accurate word, sound that the Amperex tubes have. I have no idea what you'd have to pay for NOS Amperex these days, but they are worth it. If you can't afford sexy, at least thus far, these will give you a respectable rendering of your music, unlike Chinese, Japanese, and even NOS American tubes at times, which I have heard in the past. It's pretty hard to beat these tubes for the money, and they very well may even open up further, perhaps even produce some magic of their own after 20 or 30 hours. I'll certainly say something should that be the case.
