In my opinion the RCA. The detail and the warmth is unbeatable. Dumont sounds also more detailed than the stock tube. All in all i must admit that the difference is not that big. But the NOS tubes are for sure popular because of their unique sound back in the day. There are surely tubes that are nowadays manufactured that sound also outstanding, but there is something magical with this vintage ones.
I agree RCA sounds more rich and vibrant. It sounds like it's capturing more subtlety, but the stock and RCA sounded about the same with the male vocals.
Mullard Dumont for me, but listening over the internet is going to introduce artefacts of its own. The Rode definitely sounds a little muddy compared to the other two.
Hey, Could you offer some advice. We have new modern Mic with a ECC82 tube. It’s a nice big open sounding mic, but can be harsh from 2.5 right up! Is there any tube old or new that may help to soften it ?
hi sir i saw you video...thanks for made this video...sir i want make a amp for eaephone with 6n6 pleas lead me about circuit or each lead me about this vaccum tube...thankyou
RCA stands out with instruments. Stock is the best for male vocal. Du Mont is uniquely dissimilar to the other two, but I don’t know how to interpret it’s character.
When You Buy and Put a Tube in to a Rode K2 Or Replace a Tube in Any Microphone ( Do You Have To Burn It in ) i Have Heard You Have to Live it on For 24 to 50 Hr is That True Thanks for the Video
I hear a very strange undertone when he played the guitar over the Mullard tube. If you listen closely you will hear this slight distorted undertone, I did not like that. The stock tube or the RCA sound best IMO.
Ok Mr. Das, gloves are only necessary to prevent the lettering on the tube from flaking or rubbing off, unlike halogen auto headlight bulbs that get super hot and can shatter with only the slightest amount of oil from the skin, vacuum tubes, even audio power beam pentodes are not compromised in any way from skin oil other than marring the labeling which can alter their collectible value. AND if your concern is in maintaining the tubes' collectible value NEVER clean them with a "light alcohol and water mixture" because THAT will surely degrade the tubes' labeling and degrade the tubes' collectible value. Look, your video is important and tubes are indeed the way to the most organic and life like sound but please get your facts straight before you make such inaccurate comments and give such erroneous advice and care instructions.......Fact check me and learn.
rwgamer the Dumont had resonant nasties with the guitar plus on the first clip. somethings wrong with the internal design the RCA makes the guitar sound like a real guitar. the first tube makes the bass notes of the guitar too resonant and bassy. I'm buying the RCA
I expected a recording from an amplifier output while you were playing. What I heard from a microphone was hard to judge. Why did you record an original sound?

Rca was bit soothing . Nice video very different and knowledgeable .
RCA is the ONE, BUT, that MULLARD is so SWEET, WARM and SMOOTH ...and quiet.

Great demo, thank you!
Really cool review and very good quality...
Great demo 👍👍

The video is really help,I have met u in China a couple time and your music is so beautiful
Best Mullard Dumont.
RCA for the win on voice
While I preferred the RCA, it made me wonder if the Dumont might not be preferable in a horn set up to tame ringing and shout?
Rca! None sounded bad at all, but that's what I prefer
Amperex made in Holland before 1959. What did they change?
Wow, the guitar almost sounded like a dulcimer with the stock tube.
original y rca . para ti cual es mejor en voces?

a nos mullard ecc82 will give you less highs and a nice low mid bump without losing clarity
i use 1960s RCA , nice & clean.

I think that is the common advice.
amperex did make CCA, but this amperex is not cca.
Stock for my ears

no bias adjust?
Dumont in ever way

Thank you. I cringe when ever I hear or see the tube glove myth.
Thanks for this comment
Good to know. Thank you for the information and helping make this video even better.
can you test more tubes and include some JJs?
jj suck, they are muddy as fuck
They pretty much sound the same to my ears. Sounds like the Dumont has the least noise however.
rwgamer Yes - My experience of the Dumont is a little more open and smooth sound, also less harshness on the mark tree as compared to the RCA.

You'll have to listen with decent headphones. Headphones under $100 usually don't have the detail and resolution.
In a blind test no one would ever be able to know which one is which, and if used all in one track no one would know where the cuts are.
Du Mont all the way.
There's another alternative, that hasn't been shown here unfortunately: The Amperex Philips made in Netherlands.
Agreed, better than Telefunken.
@@joeshmoe781 Did you compared them personally?And how they sound?

I think the recorder is the limiting factor here, not much variation or subtle
