DNA Stratus 2A3 amplifier - first impressions - Page 142

If the LCD3 is your main hp with the Stratus, then the mesh-plate EML should be your only 2A3 tube IMO. Much more linear top to bottom and more dimensional sound stage than the solid plates. Superior detail extraction in the mid to high range where the LCD3 really shine. It my favorite 2A3 with darker sounding hp's like Audezes and HD650.[/quote]

Thanks. I wasn't using the Audezes much until I heard them with the Stratus. It woke them up and gave them more headroom and excitement compared to my Soloist. I will be checking out the Meshes.

Another way to put it, the solid plates are more 2D. The mesh plates 3D.

Would you say the same for  LCD 2?

Yes, all Audeze's.

To my ear the EML mesh is a beautiful sounding tube a little thin compared to Shuguang Nature Sound tubes. The Shuguang's are fuller sounding and have more depth with the LCD3s. A Voshkod 6N1P driver adds some top end detail and sparkle. I absolutely loved the EML mesh until I tried the Nature Sound (they need at least 100hrs burn in to open up). I have had nothing but bad luck with Psvane WR2A3s (1 out 12 did NOT get noisy) BUT, those are the best sounding 2A3s I've ever heard in the Stratus with LCD3s.

Anyone using 274B tube for rectifier in the Stratus? Not sure if they work in the Stratus.

You`ll find a post in this very topic where Donald says it is not optimal to use the 274B as a rectifier for the Stratus.

what about gz37?  gz34?

post #2123 of 2128

Posted previously sometime back, the 274B while it may work and even get music playing. According to Donald the 274B is not a good match from an electrical spec perspective.

Also sometime back in this thread, Donald does not recommend using indirect heated rectifiers as they're built differently compared to Woo's where they both work.

Thanks for the feedback. I think the same holds true for the GZ37 and GZ34 - not compatible with Stratus. I've had one one instance where I plugged a power tube in wrong and immediately noticed smoke coming from the amp. I NEVER want anything like that to happen again.

That must have sped up your pulse a bit! No ill effects ?

Same thing happen to me earlier this year. Try smoke and then a loud pop. Thankfully it was not the Stratus.

I have the EML 274b and it sounds wonderful on the Stratus, though I'm a bit leary now because of all this incompatibility talk. I guess I'll only use it in short spurts. frown.gif

I noticed it right away and was able to shut down quickly. I took it Donald who said it seemed to be OK but we decided to change out the large capacitors just in case - since that is where the smoke was coming from. And, had to replace the tube sockets that had been stretched. Fortunately the DNA 'factory' isn't too far from me.

I see you have LCD 3 with your Stratus. Do you also use EML's with the LCD3?
