Tin HIFI came out with one of the more "neutral" sets with the Tin T2 (original) in 2017. Most budget sets are tuned harmanish or V-shaped, so the T2 was kind of unique and was held up as the go to set for a neutral budget set for many years.
Unfortunately, some of their recent releases were slammed by consumers and reviewers, eg Tin P2, Tin T5, Tin T2 Evo also. In fact, Tin HIFI had to release a "pro" version of the T5 and P2 just a few weeks after releases of the originals, to retune the tuning. Tin also released the P1, one of the cheaper pure planars which has a cult following, but I found it a pain to drive and it lacked bass. Tin also had the T2 Plus which was a good U shaped set with excellent tonality and timbre, but bottlenecked at technical performance.
As for the T2 Evo, yes. It is not that great IMHO. Thin note weight, shouty with timbral accuracy a bit off for vocals. For the same price with a similar tuning, I would recommend the HZSound Heart Mirror over it. The T2 Evo isn't an evolution as such, I would also recommend the T2 Plus over it.
The most disappointing thing is that in the T2 Evo, the MMCX issues have not been fixed. My set had such a tight MMCX that I needed tools to remove it. My T2 Plus had a loose MMCX out of the box, it was spinning like a windvane. There are so many MMCX complaints on forums for the T2 series and T4 series.
More of a case of one step forward and two steps back with the T2 Evo.
Tin is releasing a P1 Plus upgrade of the cult classic P1 planar, so let's see how that goes.
