The Reference 6SN7 Thread

[bcowen]

Sound promising those Melz 1578 and 50 people? Well count me in as 51st and Bcowen as 52nd. Sounds like the United States of America.

Well I forgot I have these Tung Sol 6f8g black glass round plates rebranded Art (Garfunkel) These are selling for https://www.ebay.com.au/itm/333518372841 and mine are NOS NIB but I've got about 20 hours on them now.

Those Tung Sols are supposed to be the cat's meow. I have a KenRad and a Sylvania which both sound nice (but not spectacular). Haven't been able to find a Tung Sol for a price I could live with....yet.

There woke up my overseas friends while am enjoying my day on the pool

Don’t tempt @bcowen: water & golf carts are like north & south poles of ...

We have in excess of 1500 tubes including equivalents. Most of the folks involved in the final testing are 20-30 years of age, a few in their forties, after age fifty people tend to lose an octave as I recall. Now as far as selection, only eight of us were involved to rate what we believe are the best 52. To be towards the top tells you a little about some of the Melz, and we rate on 25 criteria.

To evaluate 1500 tubes ? Hahaha.... I rather mow Bcowen's lawn. No that's an impossible thought.

Me? I'm saving my ears for Fotons with He1000se. If I could only have one headphone, it would be this.

My choice is Focal Utopias but in a couple days I will hear ZMF Verites, my second choice. The only other headphone I wish to try.

It's a Foton 1539. It's a premium version of a 6N5P or maybe a 6N1P....seems to be conflicting info out there. Pinout is the same as a 6922, and the ratings are within 6SN7 parameters so it shouldn't cause a meltdown or house fire when used as such. Unfortunately the mower got the best of me today and I haven't had time to listen. Finally got the electrical problem solved and now the carburetor is leaking. Things just don't last any more...I mean the thing is still fairly new at 20 years old, right?

IIRC the 6N5P is supposed to be the equivialent of a 6CG7, which would explain the 6922 pinout and 6SN7 parameters.
Funny how that works out…

Isn't a 6N1P just a 6922 with a more demanding heater? <insert ex-wife joke here>

I read your mind completely because I’m at the shop now comparing the Utopia with my He1000se using a Questyle CMA 12 Master.

I had the ZMF Verite LTD Open in Pheasant wood for more than a year.

Impossible because of the synthetic turf @bcowen had installed...chronic chore avoidance syndrome...

I am now going tubeless with Odin Empire Ears and Astell & Kern.

Never considered IEM before but this is very good. Outrageously good.

Are we still on 6sn7 thread ?

I have owned a lot of headphone amps but now I just match up with the Incubus and the sound is where I want it to be be. Unless the Verite performs better IMHO I will pass.

Headphones and amps pairing are a personal choice and I wouldn’t influence anyone on what they should like.

This short session between He1000se, Utopia and from memory my Verite Open, my preference are:-

He1000se, Utopia and Verite Open in that order.

Not sure why I sold off the Questyle CMA 12 because this Master version at the shop is really good with both headphones.

Each to their own, I do not care for Hifiman at all. Sennheiser would make my top three.

Yes, the more I read on them the more it looks like they are a close match to a 6N5P and/or 6CG7. Some sellers list them as a 6N1P sub, but then some sellers are also very confused.

LOL! When I was in California, my back yard was about the size of a 2-car garage and the previous owner had put in synthetic. It looked good from a distance, but felt like crap under your feet. If it had been real grass it would've taken longer to get the mower started than to actually mow it.

 

[HTSkywalker]

That's because they're RCA's in GE clothing.

Now I feel much better
