Project Debut Carbon paired with..

Howdy. I have purchased a Project Debut Carbon with a Phono Box MM. From my previous setup I have an old pair of Sony SS-210's. [Here's](http://www.worthpoint.com/worthopedia/vintage-sony-speakers-set-model-ss-135217868) a link to someone selling a pair if that helps. Silly me didn't realize I could not just plug those guys into the preamp. So, correct me if I'm wrong, but I see three options:

* 1) Buy self-powered speakers. Replace the Sony's. * 2) Buy an amp/receiver. Then I could still use the Sony's. * 3) Buy a receiver with a built-in preamp. Still use the Sony's but get rid of the Project preamp.

That I would only want to do if someone tells me that a receiver with a built-in preamp is preferable to an external preamp. I haven't really seen that around but I wanted to throw that out there in case anyone has a feeling about it.

The main debate is #1 v. #2. I like the idea of a receiver for the control and I could also use it with my TV. Am I being stupid to keep the Sony's though? I worry I'm bottlenecking the quality of what I've bought so far if these speakers aren't that great. Any opinions/tips on any of this would be greatly appreciated. Thanks!
