I have little doubt that it will be a nice sounding IEM. Ibasso makes solid gear for reasonable prices.
Will it be the best of the best? Probably not, but a safe bet for the risk adverse as it's backed by a good brand. I'd pay a little extra for an ibasso product versus other random chifi brands.
Yeah they look like a very reputable brand to me, though as I said I haven't tried their IEMs before, but reviews are quite favourable for their gear. More good quality CHIFI products is good for us consumers and also makes sure the western brands stay on their toes and keep their prices low for us.
Though it is iBasso's first foray into a pure multi BA set. I'll be interested in first adopter reviews on the tuning. It's also good they are using knowles instead of the usual CHIFI bellsings.
