Hi, and thank you for your advice. I recon its much truth in what you are writing here. I have "burned" myself on this, so I absolutly don't buy anything without trying it out on my speakers in my room first, or having a deal where I can return the item if its not "doing it" for me.
When it comes to my speakers, I have now tried 5 different amplifiers. But the thing is that while some of them do fix the issue with recessed vocals they tend to miss something in the other end that some other amp have. I have recently tried out the new classe 2200i, and though it had a much more detailed and wider soundstage, and had a much more clearer voice than the parasound, I did think it lacked something in the bottom end that the parasound do have.
