If you're looking for a superbly built IEM with a reference baseline beautifully spiced with a subtle touch of organic that you can adjust with the flick of a switch, then the SA6 holds fantastic value for the price and will be tough to beat! It packs impressive resolution and a remarkable tonal accuracy across the range. A very engaging reference IEM, that follows in the footstep of hallmark IEMs such as the InEar Prophile 8 at a fraction of the price.
If you're looking for an engaging entry level reference IEM with solid technical foundations and an emphasis on vocals, along with good sub bass extension and rumble then the SA3 should definitely be on your list! If you want a more organic take and can afford mid tier pricing then check out the SA6.
If you're looking for a highly engaging IEM featuring a balanced and smooth signature with a great deal of fun in all the right places and a very rare level of refinement at this price point then look no further, the DK-2001 is in my opinion a gem and a steal at its price! It clearly shows the mastery of a manufacturer that has gained superb insight from developing a hybrid lineup for quite some time now.
If you're looking for an IEM with class leading dynamics, spot on accurate timbre, fantastic speed and beautiful textures then look no further, the Luna will take you to the moon and beyond! Dynamics alone sets the Luna apart and it sounds different from anything you've heard. It's in a different league altogether and the reference yet organic tuning translate into a unique listening experience with a fantastic sense of realism.
