i not sure either my pk1 is burned in or not.
however. channel separation and soundstage still a step better than pk2.
but pk2 is much forward. everythings slam in your face type. good for blasting some music.

wow.. u are so much humble..
MS2 already not noob liao.. lol

the list never updated ever since the first time.
lol

i think so. i will bring 650 back.

fast fast sell little dot 2++ and grab this secret lah.

imho. the current version of secret amp already gone through a lot of modification which takes longer than 1.5 years to debug, and fine tuning the sound.
the second version won't come out that soon.

lol
infact.. just to get the first version into mass production already has a lot of trouble..
and imho i think the second version is not even have scratches on paper yet.. lol
and i think the current secret amp is already the best that the maker can do already he really can't think of any improvement over the old secret amp already.
if there's different version. it will be whole totaly different amp at different price range.

maybe a much cheaper version... for entry level user..
or maybe a tube amp version..
or maybe a desktop amp version.
i am pretty sure it won't be any model to replace the current secret amp anytime soon. as any improvement that shall be made had already improved at 27 different prototype. lol. thats a number i get from yuheng..
that secret amp i had involved is first 10 generation. then they goes further to modify it. and i sort of confirm it has total of 27 different modified / improved prototype.

what else to improve?
lol

as enigmatic said. the battery inside is detachable.
can be replace with bigger battery and the battery pack still running on testing.
not sure when will release.

u come and hear again my pk1. now the bass finally come out already .lol.

i though u heard my AEGO M has bass already?
lol

lol
u still in audio?
i though u quit..
