Impression time - sorry mine will not read like a polished professional kind; just listing down my thoughts. I am at around 100 hr point. Mine is a speaker based setup.
Every other DAC may be able to retrieve all information but what matters is the rendition and that is what is addicting here.
I have noticed that Sting's albums, generally, have complex recording and Yggy is good with those too.
Might sound funny, Yggy shows you how good Pandora is in doing their job. Listen to some Paul Taylor, Marion Meadows, Dav Koz stuffs, you will love it.
Yggy lets you enjoy every bit of music. I earlier had the tendency of ignoring (unconsciously) instruments played between passages in songs but now, everything is played so beautifully, you enjoy every bit of it.
Over a period, it lets you identify houses of recording. Since I am from India and there are 3-4 recording labels, I can now distinguish between the albums recorded by different recording labels. The ones recorded by Sony are best.
I am feeling like I wasted all my years listening to just probably 50% of what is there in a CD.
Yggy also proves that this DAC thing is a complicated science and I am not sure why all these big names in HiFi business have been producing crappy CD players.
I can confidently say that anyone who has still not crossed $2000 mark for DAC, should try Yggy.
I can also say that in future if at all I have money for any expensive DAC, it will be a daunting mental work to decide on a new one.
