Do We Need An Expensive DAC/AMP?

This is my first experience with a dongle DAC/Amp. It's a truly fantastic little device. The output is so clean, well balance and powerful that it can easily drive a 50 Ohm headphone with amazing ease. My phone has transformed, literally, into a Hi-Res device with a tiny investment!

Now, the primary question is do we need an expensive DAC/AMP in the first place to listen to good music? The answer is a resounding NO. The pursuit of HiFi/HiRes has its own pitfalls. It's a trap. It's just another way to waste your hard-earned money. Musical tastes and preferences are highly subjective, and the same equipment won't satisfy everyone. So, the cardinal rule is this one: invest in a good headphone or IEM. A good one means the one that is well tuned to your own tastes and preferences and do not necessarily mean a very expensive one. There is no need to buy a very expensive one to sound good to you.

Back to the question of DAC/AMP. Investing in hugely expensive DAC/AMPs is an absolute and criminal waste of money. Do not fall for the reviews on YouTube or Headphone Zone. Test it well before you buy, if possible. An inexpensive dongle DAC/AMP (7Hz-71) is serving me much better, both on Android and Windows. Sadly, I wasted 15000 INR on a FiiO K5 Pro ESS keenly anticipating a huge difference in music quality. Not even an iota of improvement! Then why pay 12000 INR more? Invest in a good Headphone/IEM. Buy a very good DAC/AMP like 7Hz-71 or Apple Dongle (INR 900/-). Install USB Audio Player Pro on your phone. (INR 500/-). Use the equalizer on your music app to adjust your equipment to your musical taste. That's it.
