hey all,
i have the hifiman sundara planar. its the Little-Dot MKII will good for planar?

Based on personal experience, the Little Dot MK 2 works ok with efficient planar magnetic headphones. However, given that it is output transformerless, it is better suited to high impedance dynamic headphones where it excels. I really like the synergy between my MK2 and Sennheiser HD600 and HD6XX.

Jimmy, thanks for the help.
Are the valves I'm using - 6ZH1P-EV and 6N23P Voskhod - not from the EF95 family?
I don't notice any distortion using in-ear like the 7Hz Zero.

Here's a tube rolling guide for Little Dot headphone amplifiers. I believe that both of the tubes you mention are listed there. Good luck!

Peço conselhos aos amigos.
Comprei um Little Dot MKII com os tubos Voskhod 6ZH1P-EV e 6N23P que funcionavam sem destruição com os fones de ouvido Philips SHP9500.
Vendi o SHP9500 e comprei o HiFiMan HE400SE que apresenta distorções quando aumenta o volume.
Eu tentei com a GE Jan5654W ea alterar, mas não funcionou.
Little Dot MKII não veio com o kit de modelos originais.
Está definido para EF95 (6J1).
Eu tentei todas as configurações de ganho possíveis e as distorções em volume alto continuam.
Alguém tem alguma ideia de como se livrar das distorções?
HiFiMan HE400SE0 funciona com Topping L300SE0.
Acrescentar uma ajuda.

A help! Can I use the Little Dot MKII pre output to feed the Schiit Asgard 1 input without damage to the Asgard?

Question for you guys got the HD 6xx what gain are you guys running on this amp ?

Question for you guys got the HD 6xx what gain are you guys running on this amp ?

I used to run it on Lowest gain because all others are noisy without an artificial center tap.

 

[califmike33]

I'm running mine on 10 I don't have any noise.

I'm running mine on 10 I don't have any noise.

Lucky you! I sold mine because of this. Now i am super happy with my schiit asgard 2.

 

[califmike33]

Yeah maybe I'm lucky I mean I can turn it full blast no music it's dead silent. And with the 6xx if it's not on 10 I can't get enough volume now I don't have to go past 12:00 or blow my ears off. Thanks for your reply I was going to try the Valhalla II, but I picked up this amp for $100 so so far it seems fine.

Can't really find any information has anybody taking this thing apart and try to upgrading some of the capacitors and the internal stuff? Doesn't seem to be a lot of information on this.

My Little Dot was purchased new from the manufacturer very early and has all quality components; apart from the cheap plastic knob and poor stock tubes which I replaced right away. Seems like parts and Company QC went downhill the last few years from what people show and say on the inter web.
I have never had any noise or problems driving my 250 and 600 ohm phones. I reset the gain settings a couple of times. I still use it every day.
I don't think the amp sounds that good with low impedance headphones like 32-50 ohm

 

[califmike33]

I think there are a few cheap parts in mine, i bought it used, no idea how old it is. I have to say though for $100 its sound really good.

As a new owner of the LDMK2 I noticed it loves to pick up wireless signals. My router sits right next to my desk where the amp is located. When I disable the 2.4ghz band on my router I can hear the static/noise completely stop on my amp. 5ghz doesn't seem to bother it. Hope this helps someone!

Yes, my LD MK 2 picks up some noise if it is on the same circuit as the furnace next to the treadmill. We moved to a newer place and no more line noise issue.
