I've pick-up a pair of TJ Fullmusic 2a3/SE from local used classified. The previous owner planned to use them for his preamp diy project. Apparently, these tubes had significant followers among diy. But, I was a bit reluctant as they were pricy and TJ had high failure rate for its 300B (according to local tube-maker).

I'm quite happy with my pair of sophia (with u52). Holographic soundstage, smooth, seductive mids, and extension on both end. However, I felt that I kind of miss the texture of vocal and instrument (I felt my system a bit too smooth, and miss that raw nuance of the music). So I decided to pick up that tubes a few days ago. Previous owner said he run about 25hrs. So far, I had about less than 25 hrs. And they do have the texture that I looking for. It still lose a bit of the soundstage of sophia (maybe still need more burn-in), a bit forward in vocal than sophia, but have the texture to die for. To compare with dac, IMO, sophia had that bit that I like from a good implementation of ess chip (soundstage, smoothness), and TJ 2a3/se had that texture from multi-bit dac. Hopefully, these pair will not have that failure issue.

This, I had to assume, was part of the Audez'e house sound.  T-1s, HD800s do not do this, at least not on my amps.  They both have their own frequency signature but they are not humid, not with my WA-6SE (with the magical EML 274B mesh) and my Wright 215i (with NOS Siemens EL84s); with these, they both reach for the stars.  The D7000s do not do this either.  They are tough to find the right amp for but my SAA-modded Phonitor has allowed them to sprout wings.  The closest I came to being able to see through to the music of the LCD-3s has been using the ECC35 driver with KR PX4s in the ECBA.  The extra oomph of the 6SL7 variant clears a lot of the humidity away - for the LCD-3s as well as for the HE-6s and K1000s...

Until now.  The the Stratus has brought out THE BEST I have ever heard from the LCD-2s and 3s, the K1000s and the HE6s -- AS WELL AS the T-1s and HD800s, which is where the ECBA cannot compete - at least at early blush.  The dynamic punch of the Stratus is like a hot desert wind at sunrise, drying the dew upon contact.  The deep extended bass actually shakes my body and the sparkly treble bites into me, creating a kind of sonic harmony and rightness I have been in search of since I started this, ahem, hobby, a while ago. 

Well done, Donald!
I quote the above post from fejnomit because it just described so well how LCD-3 sounds out of EML 2A3. I was previously using the Sophia Princess with the LCD-3 and I thought it already sounded very good, but the EML Mesh just brought a higher level of clarity, which brings you closer to the music. In my case, the EML tube has brought the LCD-3 to the same level of enjoyment as HD800 driven by Stratus. I have also swapped my EML 5U4G to U52 as I thought the EML rectifier together with 2A3 sounded a bit too clean (solid state amp) sounding to my liking. This is purely my preference for the tone as both rectifiers are technically on the same level IMO, so I won't be surprised others prefer the EML 5U4G. It could be be new toy syndrome, but I find myself grabbing the LCD-3 most of the time nowadays listening to my pop songs. My LCD-3 set up surprises me all the time making these supposedly ordinarily mastered pop songs sound like well recorded high res music. As LCD-3 is more forgiving than the HD800, I also find myself listening to more songs in my collection.

although not an Audeze fan per se here, I have to say that I really liked LCD3 when I heard it on the Stratus. Anyone looking for a tube amp for the 3 or 2 should def give the Stratus some serious thought and/or listen  

 

Glad you are still liking you Stratus Froger!

Would the XC pair well with the Stratus?

Good question - I have asked this before but today I am very forgetful. Someone on here has tried the Combo and really liked it. I think most people like EML 2A3's with the Audeze cans and I think the same would apply for the LCD XC. 

 

I think the general consensus is to find a tube set that is a bit brighter because it seems to suit the planar's that way with the stratus.

Thanks for that. The search continues for an upgraded amp to pair with the XCs.

post #1823 of 1920

The Stratus should pair well with just about any headphones especially the XCs. With my LCD3s (with fazor upgrade) I enjoyed the EML Mesphlates but find the Shuguang Nature Sound tubes have a bigger bottom end and more extended top end. The Psvane WR2A3s are still the best I've ever heard with LCD3s and Stratus BUT I've posted before all the trouble I've had with Psvane tubes. To my ears the Shuguang Nature Sounds come close after a little burn-in.

Well, my deposit is in and now the wait begins smily_headphones1.gif Donald is projecting about 3 months from now. I plan to keep my Auralic Taurus Mk.II and see how the two amps fare against one another. I am extremely excited and will have to try and pass the time by stocking up on tubes biggrin.gif

I have already begun my tube hunt

Congrats! I'm still eagerly waiting for mine and should be arriving sometime next month! :bigsmile_face:

post #1827 of 1920

Congrats to the new Stratus owners or soon to be owners! You made a great choice.

 

My favorite tubes on the Stratus at the moment: Sylvania Double-Flat Plate 2A3 + RCA 5U4G + Westinghouse 6BQ7A => HD650.

 

If you're going NOS 2A3 on the Stratus, def go Sylvania. I'm getting killer soundstage and beautiful midrange on this setup. Enjoying it so much I've sold my HE500 and LCD3(!). (It's also nice to have the SR009 as backup ;)

 

Thank you Dubstep Girl for that rectifier list. Will def try out some of those tubes.

 

Heads up! I'm putting up my EML 5U4G tube and other rectifier and driver tubes for sale. Check out the ad and PM if interest.

post #1828 of 1920

My congrats to new Stratus owners too. After more than a year and lots of tube rolling my current set-up is Shuguang Nature Sound 2A3s, cryo pearl 6N1P and Marconi U52 rectifier. I find the Shuguang's to have a fuller bottom end, a more extended top end and more separation than the EML meshplates - surprisingly. I'm listening through LCD-3 with fazor upgrade.

Very interesting thoughts! My understanding is that RCA made the 2A3 for Sylvania so I would not imagine much (if any) difference. But I look forward to hearing for myself :)

 

Current Tubes that I have to try are:

2A3 - RCA dual plate, grey plates

5U4G - British Brimar

5U4G - RCA Military 

 

I tend to prefer NOS tubes to current production but will likely experience with at least 1 new production tube at some point to hear them

post #1830 of 1920
I'm no tube historian but I'm pretty sure Sylvania was the OEM of most of its own tubes and tubes of other companies. I've seen old RCA monoplate 2A3's with Sylvania markings on the bottom base. Even the similar looking RCA and Sylvania biplate 2A3's from the same period sound different; Sylvania with the sweeter midrange and top extension; the RCA with the thicker mid to bottom. But again I'm no historian.

Either way I prefer the Sylvania 2A3 to the RCA due to its more linear sound which is the idea sound signature to match with just about any headphone.
