@Sonywalkmanuser I wrote them to
@andrewski..or I think so.
I was short because everything had already been said
I can add that the Swissbit works wonderfully on Qobuz
( settings / select storage >> for local *and offline* music play
); result is an easier separation feeling for instruments, a cleaner background and foreground for parts of the mix, more of a sense of 'vacuum space' or black space among them (although depending on record ofc ) , and as you said : things materializing a better holographic appeal .
Holography is a chimera in the IEM world, depends on a moltitude of factors : recording , iem , source , iem technicals and frqs graph etc etc ; it results to me as an 'audio trick' that involves a shift that the hearing and brain' audio decoding ability operates adding a further plan of consume (?), where parts have a more 3dish place , a sort of ' added separation ' between the music flow and sound flow from their physical rendering attributes, so that the latter -even when artificially made up in the mix - becomes more evident ; and it is something I like when stage is big enough, but smthing I don't dig too much when stage is closer or narrower ( give me more of a claustrophobic feeling in this case ) ..even though its great for little acoustic ensambles of instruments ..and at times I just like 'music' ..sorry for lack of better words
While i made up my mind more lately on what analogue means in real life and in music reproduction -and how the two things should be related, I am still very much lagging when grabbing the whole of what holography is in sound , so hopefully iem and hardware builders are little more proficient then me and evolving its significance through r&d.
Now I am also curious if I can tell a difference /downgrade ( or not ) going from Swissbit to Micron .
I am still delaying my update to FW 1.08 on my 1ZM2.
Happy with 1.07 now. Don't wanna potentially spoil that considering how big a change it seems to be, for some here at least?
makes sense
I was searching in web for how to revert back firmware on 1am2, found smthing about it
Then magic happened, i changed smthing in dsp , and now I am happy with 1.08
>>for 1am2<< it seems that fw1.08 adds some things while takes away smthing else , results feels like a quite major change for sound and overall positive.. there's a change of color to accept - or 'a price' audio eng had to pay for adding the goods: the color goes from a sparkling, light fresh blue to a slightly warmer stronger and bit more satured tone , ..and color is not fresh blue anymore , anyhow. Not as warm as a Shanling but -sure thing- closer now then before
Curious as well on comparison between 1.07 and 1.08 in the zm2, but I dubt we will see soon a proper A/B
As
@Sonywalkmanuser wrote , the thirst for dynamics ( for lacks of dynamics) lessened significantly , or dramatically , with last update ; that was a major plus in my book for 1am2..but this would possibly be a good reason also for 1zm2 , I've had extensive use of it in the past and I found dynamics a major fault in it
..with previous firmwares.
or
@andrewski can tell it better then me
you could tell us a brief comparison between 1zm2 and 1am2 on fw1.08
if not , then why dont try it yourself ?
