I had to travel for a few hours today
The road trip would had been quite boring if it weren't for the meze 99 Classics (my main headphone) and iDSD BL!
The chatter in the bus was quite unbearable, but the problem was solved very fast by connecting BL to my smartphone via an OTG and connecting 99C to it! The process is really easy and iDSD doesn't look out of place at all with my phone. It is possible to watch movies while holding both in hands and comfortably - for more than one hour and a half without any problems.
Acoustic music is one of the most shocking parts. The few classical and acoustic songs I tried with it sound way more life-like. There is a certain analogue, "real" feeling to sound when using BL. The transient response is way off the charts and same can be said for the realism of soundstage. You can imagine the music having soundstage with mix max as well, but with iDSD the music doesn't come from a soundstage, it comes from the place it is supposed to come from.
Guitar sounds have a power feeling to them. To describe it, guitar notes sound changes like it does when changing from a cheap guitar + cheap amplifier to an expensive guitar + amplifier if singing live. There is a more depth to everyone note, more sway to what music is. Since I've been there when music was recorded, the only way I can describe this sound is truly life-like and analogue
By the way, this is the second day of my impressions, and all the fun and excitement is still there!
