Hi there. I am new to this, so i know pretty much nothing. 

I got a Pro Ject Debut Carbon (2m red) TT , and now i need an amplifier. my questons are:

Is it better to buy an amp that has a preamp inside, or is it beter to buy 2 sepparate ones ?

What amplifier should i buy? price range would be 600-900 $ (max)

I own  Dali Lektor 8 speakers.

Thank you
