2 days ago I have compared Fiio X7 (World Review Tour unit; this DAP is Android based and has a touchscreen) with LG V10 in a shopping mall.
To my surprise I have learned that the V10 was introduced in the Turkish market about 10 days ago.
I had only Fiio X7 and Havi B3Pro1 iem in hand to make comparisons with LG V10. In the same day (may be 1 hour before) I have compared Cozoy Aegis with Fiio X7 so I have good sound pitcure in my mind about the sound of Aegis DAC/AMP.
I have loaded the same music with a microSD card to the V10. So I have listened exactly the same recording with both.
It was late at night and the shopping mall were going to be closed after 26 minutes so the place were very quiet enough to make healthy comparisons (no customers and background noises). Havi B3Pro1 iem's isolation is above average so it eliminated further noises.
I have manually selected the hifi-dac and adjusted its sound on V10. Since B3P1 is a power hungry iem (almost like a full sized can) you can see how much volume B3P1 needed from the hifidac of V10 (please check the second photo). Since the high impedance switching was not triggered due to 32 ohms of B3P1 I had to push the volume very high on V10.
I have to add my sound impressions: V10 sounds very close to Aegis. Its like they belong to the same family. Compared to X7, I found the V10's sound signature more musical and slightly warmer. X7 sounds slightly more detailed compared to V10 and X7 has slightly better separation and imaging.
But "on the go" I can be perfectly content with V10. For critical listening I can prefer X7 over the V10 (by a small margin).
But the lush, musical and fuller sound of V10 was really entertaining (I mean in comparison with X7). I also support now that the sound quality of V10 is really up there with some midfi DAP's and it stares its eyes to the high tier group. V10 "might" eliminate the need for many current mid-range daps -as said by many in the thread- unless you want to separate your music from your phone... Or unless you want some technicalities like: manual gain switches, lineout, coax out, balanced out, external DAC features, etc...
Havi B3P1 also sounds fuller with V10 compared to X7 headphone out.
IMO, X7 is still a "slightly" better source sonically (also I mean better for overall DAP features or technically). And the X7's lineout is a beast to beat. I didn't add the X7's lineout sound quality to the comparisons (didn't have time to add a portable amp there) but I am sure that it will be clearly better.
But X7 is a delicate piece of equipment. Its raised glass part couldn't stand punishment like V10. X7 is thick and heavy. Its screen is smaller and incomparable for looks and resolution. X7's charging takes too long compared to V10. And the battery endurance is incomparable. Hands down V10 is better for these features... Also V10 can support the future generation of micro SD cards up to 2TB space where X7 currently supports up to 128GB (no two card slots).
Verdict: I am going to buy LG V10 whenever the price gets lower here (sells at 900+ USD at the moment). And I will be using only V10. Holding the V10 in hand and listening through it, was an "instant fall in love" experience for me
HifiDac Activated, Havi B3P1 needed the volume to be raised too much. 32OHM couldn't trigger the internal AMP's high gain feature.
PS: Sorry for my above crappy pictures... I shot these with my crappy compact camera... then transfer the shots to phone and these are the results...
