I think the performance/price ratio of this product is at a high level both in terms of processing and sound. For this money, you probably won't get better sound and the advantage for me is that whenever there is a problem, you just need to load the device and any complaints can be settled verbally in the store (an advantage compared to online stores). I think that buying the device was a good choice and a step towards high-quality music reproduction. The only disadvantage is perhaps the missing digital equalizer due to the load on the device (sometimes you don't know how much you can afford on the device).
