That listing is for the short version of the tube, you definitely do not want those.

The tall version of the 6HM5 is the one to buy.

Thanks - I did not know that there are two versions; only have the tall one.
BTW, I have made an observation over the years that larger tubes often sound better. I am sure that there are exceptions, but somehow it appears to me that the larger/taller tubes are better sounding in general.

I just purchased the little dot MK3 and was wondering what upgradeable replacement tubes I should purchase for this unit to improve the sound further.
Thanks for your help
I run these power tubes https://www.ebay.com/itm/313238472630
and my favorite driver is the 1950's Tung-Sol 6AK5 square getter.
I have had my amp for many years and this is the best sound I have come up with.

Like TrollDragon I also ran the Yugo 6HM5 tall bottles, great tube in my LD. The Sylvania 6HQ5 is also an option.

Hey guys,

i buy little dot 2 + sundara , now i connect him to Maverick D1 dac - do you recommend me to switch to another dac?

also i would like to get a recommendation for lamps to little dot 2, most of my music is authentic musical instruments, male voice, lots of emotion, looking for an intimate stage, as close as the attached youtube:

thank you all

The Little Dot MK 2 is an OTL amplifier with a high output impedance not designed to drive low impedance planars like the Sundara. It cannot provide the current required to make planars come to life and sound their best. You would find better synergy using a hybrid amplifier or solid state with those headphones.

Just looking at the specs for the Maverick D1 and it has a 1W headphone amplifier that should drive the Sundaras very nicely.

TrollDragon - hey so i will sell it..i love the sundara.
i didnt like the amp mavrick d1..
You would need a hybrid amplifier if you want a tube type sound with the Sundara or you would have to go to an OTC (Output Transformer Coupled) tube amp if you want a pure tube experience, but those start around $1K and go up from there.

Can someone tell me what these tubes are. I am trying to figure out which tube family they belong to. So I can set my jumpers on my amplifier correctly.
Its hard to make out the writing on the tube. it says 6 and HQ5 below.

Don’t forget the Schiit Valhalla II at $349. I use it (among a few other h/p/a) to run Audeze LCD-X through ZMF Auteur. Great results 🎶🎉👍.

My little dot has settings for certain families of tubes.
I can use the 6JI,6A5K,5654 tubes on one setting
AND EF91,92 CV131,138 tubes on another setting
Do you know which of these settings are for this triode?
If you go to the Radiomuseum and type in 6HQ5 you will find listings of other tubes with the same or similar characteristics and pinout such as the 6HM5.

https://www.radiomuseum.org/tubes/tube_6hq5.html
If I remember correctly, people use the 6HM5 in the Little Dot on the 6AK5/EF95 setting so the 6HQ5 may be compatible. But I am not sure and do not want to give the OK to use it. You may want to ask Trolldragon or gibosi. Or you can ask Deyan as well.
The voltage and current draw of the 6HQ5 are certainly compatible with the Little Dot MKIII.

Thanks. You were correct. They belong to the 6AK5 FAMILY.

I tried the Sylvania 6HQ5 in my LDMKIII without issue, I prefer the Yugo 6HM5 tall bottles to them and my favorite thus far has been the Tung-Sol 6AK5 (square getters).
My LD, with a Maverick Audio D2 DAC and Beyerdynamic DT990 (600ohm) still impress the $#!+ out of me for the cost.
