I listen to vinyl records through my headphones and am currently running my turntable (Pro-Ject Debut Carbon) through a rather awful Sony AV receiver and I use Sennheiser HD 558s. I want to buy a dedicated phono stage, and then connect the phono stage to a headphone amp. The Vali seems perfect for me, especially the price point and the fact that it utilizes tubes, which I have always loved. Now, is this amp with those headphones a good pairing? I'm not knowledgeable enough to know, and want to make sure I wont damage anything or something else.
