The heat is ok. Nothing to be alarmed about. Congratulations on a fine sounding amp

It doesn't really heat up too much

Thanks for quick replys. I will share my impressions with dt880 when it comes.

Don't cover the tubes with stuff, and don't touch them while it's operating.
Can't think of much else, a little space around the amp and all is good.
post #320 of 444
Finally, my amp arrived. Definately good sounding equipment. It's amazing to hear how much sound can change while burning process. Wery good match with DT880 250ohm. I am quite satisfied and look forward for some tuberolling action.
Btw There is only one user manual inside the box and it's Chinese. Is there any download link for english version in pdf format?

Little Dot mk ll
gain 5 very good SQ with oem 6JI driver tubes + 6N6/6N6P
gain 7 suited for Mullard ef91 & ef 92 driver tubes
volume knob between 8:30 to 10:00
as per my ears, preferred music (rock/pop/new wave/nam) and SQ ... YMMV

transducers used: Grado sr325iS, Grado HF-2 F1, Grado Alessandro MS1, Grado Alessandro MS2i, Denon AH-D2000, Koss ksc75
DAC: SuperPro 707 usb DAC
source: iTunes lossless through Toshiba laptop



on 6JI


rear view .. added toggle switch (underneath the power switch) for tubes rolling convenience

nice shot bro bass_nut!
btw, what version is your board? hmmm... saw some toggle switch at the back , looks like you made some modification on your LDMKII.....
have you tried tube rolling your driver tubes? please post some SQ impressions ...
post #325 of 444
now I'm really enjoying the ld mk2 with the stock tubes at gain 10
post #326 of 444
I am using at gain 10 too. DT880 demanding that. But I think sound quality better at lower gains.
post #327 of 444
sound is tighter and snappier to me at higher gain but low gain adds less coloration to instrumental timbres but has a tradeoff of sounding soft with the stock tubes. All impressions are done using my audio technica ad900s
post #328 of 444
Are you satisfied with your AD900 into the MKII ? With low impedance cans i have some ( slight ) hissing and background noise...but it could also be the tubes ( i'm running vintage soviet 6n6p and mullard M8100 )...no problem with the higher impedance Beyer though.
post #329 of 444
no hiss on mine even at full volume, no music... even at full gain when using a quiet dac

Little Dot mk ll ... caps changed by Master Ferds ... 3 pairs 8)

i think mine is version 1.0 bro Voltraizer
from this


now here it is ..toggle switch at rear face plate for driver tubes rolling


SQ output quite pleasing as i matched this baby on various Grados/Alessandros headphones, Denon AH-D2000 and Koss ksc75.. fast transient attack & ultra low noise just like very good s/s amp SQ.. volume knob between 8:30 to 10:00 enough for my taste as i listen to rock/pop/disco/new wave/nam/motown/ost albums

btw, 1/8 output jack added at front face plate to eliminate need for adapter
