Thanks for understanding. I do notice that my Focal Utopias are more sensitive to the hum than my Sennheisers. Maybe its the difference in impedance? The Focals take less to drive so it may be that.

That definitely is it. Focal's impedance are between 55 and 80 ohm depending on which one you own. Sennheisers are up in 300+ ohm range, with a peak of sometimes 600 or 700 ohms. Same as the ADX5000, rated at 420ohms but peaks in the bass at close to 700 ohms IIRC.

That said the Elex is at almost as black a background with 339i right now as it is when it's with the THX AAA 789. Volume is at 9 o'clock on the 339i, with 6AS7GA and 6SJ7GT. Very faint hum but much better than when you crank the amp's volume.

edit -The adaptor may be introducing ground hum or just be noisy thanks to its own wiring, more sensitive headphones could pick it up

Those are the true mesh type too...some are just "mesh like" where it is just holes in the metal plate. Nice you got the hum under control. I'm still trying to find my cause or tube to reduce the hum

Full mesh 6sj7gt or equivalent seems to be hard to get. I am waiting for my Tung Sol 6sj7gt, but they also seem semi mesh.

As for hum try switching tubes, changing power/driver tubes. Sometimes even unplugging and plugging again my change things. Sometimes nothing helps though...

Just got up and I'm again wowed by what I hear listening with LCD-3f and LF339. This combination is smack on the money for me. Vocals are a killer. They breathe right into me. With a revealing top end and pounding bottom, it's easy to forget breakfast.....

I'm not sure why. I was so on HD800 before, then there was a spell it was the Verite (still is sometimes) but now it's LCD-3 that's turning me. I think my preferences are like the seasons. It changes.

This is very true. Perception of sound changes depending on various factors. In the evening i usually do not like highs and prefer smoother sound. I seem to prefer more aggresive sound today than yesterday. I guess this is the beauty of our hobby

Has anyone tried the 6084 E80F tubes? I have had some great results with the Amperex version of this tube and use the EF86 adapter.they are a tad taller than the EF86 tubes.

I got my Mullard EF80 mesh from Langrex. NOS tubes and clean as a whistle.

bought it in 13 Feb 2017 for GBP 6.50 then. Now it's a slight increase to GBP 7.15 each.

It seems i have exactly the same mullards

I do that daily...that’s why we have different headphones. Our ears can be so finicky sometimes Speaking of Verite...they are running their November sale and I picked up a pair of VC in camphor burl wood. They are truly beautiful and cannot wait until they arrive...the journey continues...

Congrats on the VC camphor burl wood. Remember a pic of it with La Figaro.

So it works with the EF86 adapter? No noise? Incredible. See it's so easy to spend on tubes such as these because they are quite reasonable in price. Pretty soon you will have amass enough of EF80 and variants to become a seller.

Hey Sam, great to hear from you. I see you still have great gear from your signature. Enjoy and do come back and contribute.

Yup, I’m still hoarding stuff but at a much slower pace. Are you still in Singapore? We should catch up.

I don't hoard. Every once in a while I like to change up my gear. However I'm buying much faster than I can sell lol.

What makes you think I'm still in Singapore. The last I was there was in 2018 Oct, where I spend 5 days then off to Taiwan with my wife for a holiday. I cannot travel now until this Covid disappears. So we can connect here in the meantime.

Ah ha.. maybe I misread your post.
The only new headphone which I bought was the HD560S. The Dave killed my desire to try different electronics, I honestly don’t think I can get any better than then Dave.

 

[UntilThen]

I have not heard Dave. I imagine it has to be good. For me the gear which I didn’t feel the need to upgrade is Yggdrasil. It’s good enough for me. I didn’t even bother with the upgrades because why would I touch it when it’s sounding perfect to me.

Woo Audio Wa22 and Audeze LCD-X are back home in Sydney.

A quick listen of LCD-X (20 ohms) on La Figaro 339 and it's beauuuutiful !!! No noise, hum and any anomalies. LCD-X sounding really good on both Wa22 and LF339.

Can't have a long listen though because I'm dashing off to Hunter Valley for 3 days ! Why do everything have to coincide.

My premonition is right. I'm liking LCD-X more than LCD-3f. Why? Tell you later. Wa22 vs LF339 - which is better? Tell you later haha. If I get to it.....

Tubes on Wa22 - Ken Rad 6sn7gt black glass, GEC 6080, Cossor 53ku rectifier.
Tubes on LF339 - Mullard EF86, RCA 6AS7GA.

 

[UntilThen]

Wow both amps sounding real good with LCD-X. I need to bring these back to Canberra and hook it up to Yggdrasil. That's when sparks will go off.

Nice! I guess i prefer lcd3f for the same reason You prefer lcdx but can not wait your post re: which is better)

Re: WA22 as You know i have just sold mine. Too forward sounding and not enough tubey i do consider buying WA2 to supplement my La Figaro and Burson cv2+. Do you think that makes sense?

As for now i am in audio nirvana with La Figaro with RCA 6as7g and (surprise, surprise) stock Russian 6j4p. The latter wins with Mullard ef80 and Telefinken ef86 for me. I am waitig for some 6sj7gt to come.

Busy the last few days, but got some time to sit down for a good listening session tonight. Trying out some very unique Visseaux 6J5MGT drivers with GEC 6AS7G. Extremely detailed and delicate, yet beautifully smooth. There is appropriate weight easily delivered when that is demanded. The amp is still opening up nicely, nothing near 100 hours yet but it keeps getting better; whether that be burn in, or my ears burning in, doesn't matter- sounds magical
