Is there a possibility to order both from amazon then send one back? :

I would love to but i don't live in the US. Return policies here are not as great like in the US.

I have tried the Organic and he 1000 stealth at home and I did not liked the Organic. To bright and not much body compared to the v2 stealth.
So I have the he 1000 v2 stealth now, what whas and think still is the same price as the Organic.

Where has anyone seen any discussion of the 25AX4 tubes? I don't remember seeing anything in this thread.

I've replaced my 25AX4GT and noticed extremely minimal audio impact.

The NOS versions are MUCH prettier though... VERY bright getters.

Picked up the HA-3A and it has blown anything I have used in the past out of the water.
I'm shocked I can't find too much on this amp outside of head-fi and a couple reviews online none on YouTube Minus ZMF's review.

Had mine for just under a week & agree, best amp I have owned. Currently using the stock tubes & will do for a while yet, will probably change the 12au7’s first when I am ready.

Once you start rolling, it takes the amp to an even greater level IMO.
Tried some NOS Tung-sol 6v6 andTung-sol 12au7 with the Auteur classic and the caldera thick pads.
The best the headphone had ever sounded for me, but that roll with anything else was just ear bleeding bright.
Even with the AO with the caldera ultra-perfs.
Swapped the AO ulra-perfs for the Auteurs leather and was still way to bright.
Swapped for Hytron NOS 6v6 and kept the 12au7's in and toned down the brightness but kept everything else I really liked.
Still have a few other combos I want to try with it.

Can anyone recommend fast/neutral tubes for the HA-3A. Keen to try some tube rolling but not looking for anything too warm, prefer to find something neutral with tight controlled bass, & good slam

genalex gold lion — both 6v6 and 12au7

I have considered this, had a gold lion driver tube in my HP8 & was suitably impressed. I have heard the Psvane 12au7 art series are supposed to be great also

Try a pair of Mazda 6v6gt power tubes.

For 6v6 these come to my mind:

Mazda
RFT (rare)
National Union black glass

Westinghouse with these plates (ultra rare)
Westinghouse did rebrand Sylvania or RCA tubes. So be aware to not buy the wrong tubes.

For 12au7/ecc82:

Mazda ecc82
Raytheon ck5814 windmill getter
Siemens ecc82 variants
Westinghouse 12au7 carbon plates
RCA 12au7 long grey plates
Tungsol 12au7 clear glass variants

I will add more when I'm home and take a look at my collection

Does anyone else get a noisy 12AU7 tubes that come and go?

Some days I will have microphonic noise from a tube and rotate the pair out to only put them back in a day after and they will be fine with no noise.

I had similar issues and replaced the feet on the HA-3A with these and it resolved my inconsistent noise issues.

So I guess my Ha-3a died to today, 8 month after the purchase. Strong loud hiss on the right channel, no matter which tube is used. Checked the cables and connectors, tried both RCA and XLR. It wasnt in use much, since most of the listening time goes to bliss, with occassional tube goodness with Ha-3a. So maybe 200h of listening time in total.
Curious if son-video honours my customer rights now, pretty meh, since its a rathe expensive piece of hardware which had rather little use so far.

Any update on Howe the service whas/is from Son-video?
