Best of current production 845 tubes?


Shuguang introduces the best new 845 since the United Electronics 845 W's, circa 1930's. We deserve it. I know that I rolled in just about everything that fit, in hopes of saving some life on the United's.
The Nature Series, as it is known, features the lowest noise level that I could not hear, in a long time.
At $400 a pair, they are among one of the best buys that I have heard. They are easily worth $1,000 per pair, I do not work for Shuguang, but I call things the way I hear them. Get yourself a pair of these before somebody figures out that they are significantly under priced. My system is custom. An integrated Chinese amplifier heavily modified, I had a custom made Coco-Bolo wood box made to accommodate new capacitors. It's tube compliment:
1 pair of Tung-Sol 6SU7 GTY (a 6SL7 on steroids), 1 pair Raytheon CK-5694 (a gift from heaven), it's first cousin is a 6SN7. Driving phase coherent 4-ways, 86db. Source, a custom Reference Audio Mods CD player, which feature four nines silver output transformers, which allow you to skip an active pre.

I just purchased a quad of the Shuguang 300B preimium treasure tubes for my amps to replace the stock tubes and even fresh from the box they sounded much better so when I saw this post, I decided to give these a try also. Again, I had to purchase four but if they are as good as stated I will be happy. I will post my impressions once I get them.
The new 845's arrived yesterday. These are a very impressive looking tubes! They are wider then the 845B's which they replaced and internal construction is simply massive. The Shuguang 845B's were much better then the original stock tubes in my Cary 211AE.After a brief warm up I started listening to some of my favorite familiar music. Right out of the box they were better then their predecessors. There was more detail, individual instruments were spotlighted and the already good soundstage got wider, deeper and taller. Unlike the Shuguang 300B Treasure tubes I just installed, there was no initial sizzle at the top end. The only thing lacking was the very deepest bass. My system will go down in the mid teens with authority but I am sure that as I get more time on the tubes this will come around. If you are running Cary mono blocks these Shuguang tubes paired with the RCA 5691 in the 6SL7 slot & Blackburn EL34 Mullards in the 6CA7 slot will give you the best of the old and new. These new 845T tubes are highly recommended.
I don't know if anybody is still following this thread but I said I would post a followup. I now have about 10% of the 300 break in hours on these tubes and if they are going to get better I got one heck of a deal.The bass has come around & they are definetly better then the Shuguang 845B's which are pretty good.I do a lot of tube rolling on my amps & preamp & the majority of my tubes are WW2 stock but for my 4, 300b's & 845's I have gone top shelf Shuguang. I want performance & reliability at a reasonable price.You get that in spades with these tubes.The 845 nature Series are an absolute steal. Get them while you can!
