Marco, I have owned both the Jolida JD100 (three in fact, as two were gifts for my older sons) and the Esound E5 Signature. I thought both players were quite good for the money. In my system I did feel the bass was stronger with the Esound. The big difference to me was the look/feel of the Esound compared to the Jolida. The E5 is built like a tank. I hesitate to get into the tone differences between the two as I have old ears, and probably am not qualified to give you a review regarding sonics. If resale is a concern I would go with the Jolida as not all that many people seem to be familiar with the E5 Signature. I think both players were quite enjoyable. Good luck.
