| Shuguang Treasure tubes.... The Treasures are still stunning. My fellow audiophile friend was over Monday for a four-hour listening session and was blown away. He thought that the soundstage and musicality was like never before, ranking the sound among the best he had ever h... | |
| Shuguang Treasure tubes.... I agree that a vendor break in is a good idea when they are so rough to begin with and require so much time. Believe me though this is not a customers-ears break in. The tubes change significantly. | |

| Shuguang Treasure tubes.... I guess you just have to think of it as a 6% tax! That leaves 94% of its life, for blissful listening which does make the story sound better. Also, although it takes a lot of patience, listening to the changes IS entertaining! I don't regret it fo... | |
| Shuguang Treasure tubes.... Rrsclyde, did your 6ca7s need lots of break-in such as mine or more like Bannister's KT-88s much lower time? My tubes' bass improved markedly relatively quickly, but the mids were not full or treble refined til much later, only getting close after... | |
| Shuguang Treasure tubes.... Yup. I was really surprised at how far they have taken the sound. I thought the system was resolving before, but this an altogether new level. Even from the other room I am hearing things in familiar recordings that I had not heard before. Somehow... | |
| Shuguang Treasure tubes.... The Shuguang 6CA7s win The contest by a nice margin. I compared the NOS Siemens with the same bias that I had optimized to two weeks ago to my latest settings for the Treasures. The Treasures are much more well articulated with excellent detail, g... | |
| Shuguang Treasure tubes.... I have more than reached 300 hours and have only listened briefly due to other issues, but what I have heard is very, very good. Properly biased, very fine level detail without being too forward and very deep and pitch-defined bass. The RCAs thus ... | |
| Shuguang Treasure tubes.... Good points. I now wonder how much of changing sound due to selection of driver tubes (for me 6SN7s & 6SL7s) is that they also affect the power tube idle current (hence operating range) by tenths of of mAs. Previously I had not reset bias on t... | |
| Shuguang Treasure tubes.... 200 hours in on the 6CA7s. Upon first listening after resetting bias to 34.8, the sound seemed very similar to the 150 hour mark with great vocals and detail, but with a minor lack of upper bass drive. Cymbals still a small tad less believable tha... | |
| Shuguang Treasure tubes.... OK. 150 hours for the 6CA7s on the books and some very nice improvement in the vocals and treble. Now far smoother and outstanding imaging, very precise and fast, yet never in your face. Great resolution of detail now that was previously the oppos... | |
| Shuguang Treasure tubes.... Shuggies are sounding better in the bass region; much tighter now. What I am not yet hearing is upper end refinement. It is a bit gritty and cymbals do not yet sufficiently like metal. Soundstage depth is somehow quite 3D at the moment with vocals... | |
| Shuguang Treasure tubes.... 50 hours of mixed playing and simply leaving them on. Much better today. Highs are not yet pristine (as they were for a few brief minutes after installation) but much better. A bit diffuse but now quite musical. Bass is better defined but not yet ... | |
| Shuguang Treasure tubes.... 24 hours in, they are sounding pretty undignified. Vocals somewhat distant and indistinct, no imaging, as predicted. A bit off-putting but I will remain patient. | |
| Shuguang Treasure tubes.... The 6CA7s are in the amp and biased at a VERY different setting from the Siemens to acheive the same idle current of 33mA. The current was heading for 50mA!With the WWII RCA driver tubes the sound was very fat, so the Siemens are therefore relativ... |
