I finally managed to find a chance to compare my office pair Takstar Pro82 and home pair Sony MDR-1a as direct A-B. DAC SMSL SU8, amp SMSL SAP II solid state & Loxjie P20 tube hybrid.
IMO, Takstar sounds better. More controlled, faster bass (adjustable with the "bass slot", third slot is junk tho), clearer mids (vocals, acoustic instruments) and crisper, non piercing highs. Soundstage are similar in both sets. Both of them seem not to care whether they are plugged into tube/solid state.
In contrast, MDR1a has Sony's old house sound which has the typical " average consumer oriented sound" if I can put it that way. In comparison with Pro82 the Sony's bass sounds less coherent , vocals seem veiled, and there is no crisp in the highs.
End of the day, I will pick Pro82 over MDR1a anytime, every time. Pro82 being more comfortable is a bonus, not to say MDR1a is uncomfortable in anyway tho. One thing about Takstar is that when you fold it over to place it on your neck, it will awkwardly fold in a way that the ear cups will be facing outwards, unlike the Sony, which is more conventional with the ear cups facing inwards.
Why this took me more than a year to do an A-B after having both for more than a year is beyond me....
