That would be helpful for those of us here who might consider upgrading from the IT03. Thanks a lot mate!
Just grabbing some quick A/B - Dorado is slightly warmer, easier to drive (but not by much) and feels slightly more forward overall compared to the more neutral sounding IT03.
Bass presence is fuller on the Dorado, with similar characteristics and extension into the sub bass. Soundstage appears slightly wider on the Dorado, with more width to the sound than the more "centred" IT03. IT03 sounds a little airier due the relatively thinner (but not thin) overall presentation.
Detail retrieval seem similar- not enough time to make a proper assessment now though.
Not a huge jump in audible quality between the two, but I would just lean towards the Dorado if you are looking for a more "V" shaped tuning - it reminds me more of an upgrade to the A83 rather than the more neutral tuning of the IT03.
Hope this helps?
