Forget the recordings. Did the bass sound flat to you when you tried it in person? How did it sound compared to other guitars that the store had? This is the best way to answer your own question.
I personally tried it. It sounded nice, but didn't feel it performed in its price point. There are guitars that cost less that I'd prefer more personally. For example, I'd prefer the Cordoba C9 which is much less expensive, performs above its price point, light weight, and has a great sound comparable or better than the Esteso.
