Well,esanthosh said:Amarbir,
Take typical chinese items. They are cheap. For instance, I have a Bravo V2 Headphone amp, which uses sub-standard PCB, poor power supply and cheaper components to reduce cost. But it costs anywhere between $30 to $50. So, if you even spend $50 more as an enthusiast to fix / mod and make it better, your overall cost is still within $100. I absolutely don't mind that. Similar is the case with Topping TP20 Amp. Under $100 shipped, this tiny amp rocks if paired with the right speaker.
I don't expect the same quality when I pay $800 / $500. We don't know if they outsource / label on another player, which is always possible like S:Flo and T51. But, even if they do, and considering that they sell internationally, a bit of quality control is very much required. If you pay $850 for a DAP and then add another $50 for component upgrades,.... you just missed a chance to setup a basic speaker rig.
i Am Fully in Agreement To You On This .Wehn i Will Get The Hifiman HM-602 One Unit i will Mod ,Wait And Watch
