Hi im kinda new to all this. Currently i own a pro-ject debut carbon esprit connect to a cheap pre-amp then to some bose companions but i want to upgrade. I was looking at the Pro-ject stereo box s and connect it to a pair of Dali zensor 3. I just wanted some advice. I thought of maybe going to the Yamaha As-500 but the size of the stereo box s is so much smaller so im really considering that option. Would it make a huge difference to go with the yamaha?
