I would agree. But I understand the Shuguang Treasure tube has a very full and rich (wet) midrange and the added fullness of the U52 might push it over the edge for some. I suspect the EML rectifier is not as full as the U52 (I've heard some find them on the dry side) and might work well with the Shuguang tube.
I have it on my list to test my theory, however, and one day try the U52 with the Shuguang Treasure tubes and find out for myself. There is no question the U52 is a great match for the Stratus. When I read that a tube might make a noticeable difference in some amps and very little in others, I can confirm that, in the Stratus, the U52 makes a significant difference.
it will not push over the edge. the u52 is warm but its not very fat or full as some might think. its also fast and extended in treble and bass. its more a euphonic than a lush tube imo. its a nice warmth and i dont think its overly colored, it has a very good balance
I have a DIY headphone amp using also the 2A3 output tube (with 6SN7 as the driver). The combination of EML2A3 mesh + Psvane WE274B seems to sound best to my ears. I listen to a lot of vocal jazz and baroque / chamber music. This combination sounds most neutral with great transparency and clarity. Mids and highs are silky smooth while the bottom is fast with great attack and resolution.
I have previously tried NOS 5U4G's from RCA and GE as well as the EML 5U4G. My preference is still the Psvane WE274B.
For those who may be interested, I have uploaded pictures of my amp to the Community Gallery under Desktop Headphone Amps.
I asked Donald about the sophia princess 274b a while ago and he told me to use only a solid plate 274b, as the stratus draws more current than the mesh plate 274b is able to provide.
would you pay that if you had the money?
yea its offensive. Having a tube that cost as much as an end game amp. It shouldn't be aloud happen but i suppose that's just the way it goes.
No, I won't....and those two tubes are probably used! I paid US$200 for my brand new Psvane replica and I am very happy with it. I would love to compare my replica with the original though..... just wonder whether I will ever get the chance to do so
