I think you know as I do mahgister how silly youtube videos are like this. The echo in the original track is intentional, it is part of the recording, though I believe there is a bit of evidence of additional room reflections where the microphone is.
There is other youtube files of this same song without this "echoing".... Perfectly listenable, contrary to some other youtube file of this same song, and of this youtube contest of 2 amplifier with an "echoing"...
For sure youtube file are not very good one, especially to judge amplifier or anything through your own audio system...
But some defect persist to any medium: harsh echoing, with unnatural timbre if they are there will be there for listening through retransmission to any good audio system... If i listen to it then hearing UNNATURAL sounds through my relatively "warm" and non fatiguing system then the fault cannot be my system....
Like i said my post dont want to be an attack toward a clearly very good and superior audio system than mine, but to his catastrophic acoustical embedding and probably a sensitive dac that would need like most, a careful mechanical and electrical embedding.... The possibility is also that the dac is not so good in the circonstance, i dont know what the dac is, but i suppose it is a very good one, then the room acoustic is the first culprit, and then the audio system all embeddings ....
I dont think that what explain this "echoing" and unnatural instrument timbre is the microphone location only....Acoustical treatment are very powerful and the lack of them in some room is cataclysmic soundwise...And you cannot save a bad room with mic location only.....I dont underestimate acoustic after 2 years experiments in my own room with a complete transformation of my modest system to a new higher rung on the scale S.Q. with NO comparison between BEFORE and AFTER...Most people which dont experience this first hand cannot believe it...Acoustician knows tough....
I know then first hand by my experiments that ALL audio system at ANY price could be transformed completely by rightful embeddings.... For me it is the reason why no reviews of audio product are nothing more than anecdotes....Objective measured reviews tough are only speaking for good or bad design and not of the sound quality for real ears then cannot be complete without listenings,,,, Only the statistical numbers of positive or/and negative comments or reviews are of any significance...
I wish you Happy New Year and the more health God can give to you....
