Old Audiophile can still be blown away

I've not posted a new thread on this site in 10 years so, that in mind, It takes something to really shock me. I've been a music lover since I can remember. As a child we had radios all over the house. A habit that I still carry on. I've had all kinds of rigs over the years all with their sound and special pros and of course their weaknesses. I always come back to SET amps and high efficient speakers. Recently on a 300B tube hunt I saw that parts connection was having a sell on the Shuguang 300B black treasure tubes. Now keep in mind that these are not the best they offer(which I've got an order in for). I've got a pair of WE 300Bs and the EMLs and KRs. I don't have the Takatsuki's but I've got all the other highly regarded 300Bs. The only reason I have the WEs is I bought them when you could get them for 500.00 a pair. It seems that all I've tried doesn't have that WE magic in lower midrange. But, until now, I got in these Black treasures today, bought on a wim because they're on sale. All I can say is that the Shuguang/Psvane tubes are the closest to the WEs I've heard. Infact I think they improve on them some. The KRs and the EMLs are good but they're dry and lifeless almost solid state sounding. Now this is all in my system with my room and my preferences so all you that want to e-mail with dirty responses can get over it. Try these tubes.
