Can it be made with a 6SN7 driver/input instead of the 6N1P?

 

Thanks

Donald is pretty set with the 6N1P tube  as I asked if I could even use the 6922  and he said he does not recommend it. I am no sure but Donald will have to answer it but I dont believe he will change the 6N1P

But I would highly recommend getting over your prejudice and trying to get hold of some HE-5s or -500s.

Matched with the right 2A3s they sound incredible with the Stratus... imo...


Do you like the HE500 better than the HE6 with the Stratus?

Some goodies arrived today...

Oh Sylvania!  Dual flat-plate 2A3's!




Sylvania Gray S-Plate 2A3's...


An all-Sylvania line-up (5U4G, 2A3, 6BQ7A)



Very brief impressions on the Dual-Monoplates. I'm getting pure refinement. Its linearity and smoothness are almost unmatched. The HD800 has never sounded sweeter. The Gray S-plate 2A3's are slightly less refined but have more air and presence which HD800 also embraces completely.

An update to my matching game of 2A3 tubes and headphones I own:

HD800 - Sylvania Dual-Flat Plates, Sylvania Gray S-Plates, Sophia Princess Meshplate, Sylvania Black S-Plates (with coiled springs or fishing rod supports)

HD650 - Sylvania (any), RCA monoplate, Sophia Princess Mesh, RCA S-Plate (Black or Gray)

LCD2.1 - RCA monoplate, EML Mesh

LCD3 - EML Mesh

HE500 - Ken Rad, EML Mesh, any tube

AH-D7000 - Ken Rad, any tube

W3000ANV - RCA monoplate, Sylvania (any)

I have another rare old stock tube incoming. Stay tuned....

Nice.  I have a pair of Sylvania dual flat plates as well and I now prefer them to my RCA mono plates with the HD800.  Along with the military Ken Rad dual box plates, they are the pinnacle of the 2A3.  The Sylvanias, as you rightly point out, are for more refined phones, and the Ken Rads are to stomp all over orthos...

Third Eye, alas, I sold my HE500s!  But I liked that combo a lot.  Better perhaps than the HE-6, although the HE-6 are sounding very nice on my Stratus right now - especially with the Ken Rads.  Better than EMLs.  The EMLs enhance the HE-6's already sibilant-tending treble.  But with the Ken Rads and even the Sylvanias, I was getting a very even, powerful,  voluptuous sound from the HE-6s today.  That being said, the HE-5s trounce them both!  If you can find an old pair somewhere they are even more highly recommended.

The real star tube is the Sylvania Gray S-plate 2A3 which I got from Brentjes for only $150/pair shipped. The Senns sound scary dimensional and forward with the gray plates. The top-end is so smooth and extending. It's like they were made for each other.

I think I need to check these Sylvania's out, they seem pretty scarce though. 

post #802 of 2334

RCA gray plates look similar and are regularly available on ebay and through tube dealers. Perhaps they sound the same.

post #803 of 2334
Usually the grey plate Sylvania's can be can found cheaper than black plates. You get more warmth and smoother top end with the black plates. The grey plates are lighter sounding, more forward in the mids and have superior air. A must hear with the HD800/650!

The RCA equivalent doesn't come close, IMO. The RCA monoplates on the other hand...

Based on feedback from fellow Stratus owners I've ordered both HD650 and HE500 as some nice change up options for my HD800. I'm normally a one headphone kind of guy but we'll see how this develops.smily_headphones1.gif

The LCD 2.2 was excellent as well when I had the demo unit here, You may as well start collecting headphones. LOL My house looks like a hifi store right now with all the review gear thats showing up. Hopefully I will have all of this done before my stratus shows up so I can concentrate on that amp.

I'll get a chance to audition the LCD's at the LA meet this summer but all the previous times I've auditioned them, I felt like my head was in a torture device.........I do have a rather large head and wear glasses so that probably doesn't help matters. I hope the HE500 is a little more tolerable comfort wise.

post #809 of 2334

i find both the LCD-2 and HE-500 to become more comfortable over time, but neither is really all that comfortable. the LCD-2 is heavy and clamps hard, the HE-500 is heavy and with shallow cups that make the driver touch your ears

My Stratus photo gallery resumes with some odds and ends that just arrived...

The triple-mica 6N1P NOS.

The ultra refined rectifier, EML 274B.

Refined + a touch of body, Raytheon 5U4G. A personal fav.

Switched out the Cardas Gold for some silver! Some new Acoustic Zen Silver Reference II interconnects.

I must admit I underrate the RCA/Cunningham's sometimes, especially with the HD800. A very musical pairing!

The unique Tung Sol Flat-plate, Cross-mica 2A3's.

A happy Tung Sol family.

 

The sound of the Tung Sol 2A3? Slightly extended at the top. Slightly less linear in the mids than the RCA's. IMO, maybe a touch sweet for the HD800 but just right for the HD650 and LCD2.
