Can you PM me

Thanks,

Donald heard my Stratus with Emissions Labs meshplate 2A3s and U52 rectifier and thought it a good combination with the U52 adding warmth and fullness to the meshplates that can be on the cool side. He recommended a similar (and probably less expensive) combo using Emission Labs 5U4G rectifier to tighten up the sweetness and warmth of Shuguang Treasure 2A3s. Just something for you to think about while you endure the difficult but worthwhile wait.

I am currently enjoying the combo of Shuguang natural sound 2A3C-T, EML 5U4G and Pearl 6N1P gold grade thanks to fellow Stratus owners and Donald's recommendation. I think it may also depend on the headphones you intend to pair the Stratus with. While the combo works wonderfully with HD800, I did not enjoy the Alpha dogs much with my current set-up.

I obviously havent heard the Stratus, but whenever possible, the U52 is far superor to the EML 5U4G.

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

Loving the LCD-3 + sophia princess 2a3's + Osram u52 rectifier + Ultra low noise pearl cryo valve combo :)

I wonder if anyone has tried the Psvane 1:1 WE274B replica.

 

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.

So the 274b is fully compatible with the stratus would be nice to see ppl try using sophia 274b...or better yet, the mighty western electric 274b.

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.
