Building a Magnepan System, Please Help...

Hello everyone,

I am going to be shortly building an audio system, my first high end set up ever. I have decided on Magneplanar 1.7 speakers. The reason is that everything I have read seems to indicate that they are the best deal in audiophile speakers and the sound signature appeals to me. But since I have never built a high end sound sytem before, I need some help in picking components that match up well with the Magnepan speakers.

I am on a budget here. I want to get the best quality I can for the lowest price. I will even get the Magnepan speakers used if I can find them. I would like to be up and running for somewhere in the $3000 range but I can stretch that if need be.

I have all but decided on an Emotiva amp as they seem like a good deal and others have said they match up well and have enough power to drive these speakers.

So lets start out with saying that I bought a used but good condition Magneplanar 1.7 speakers for under $1500.

Then I bought an Emotiva XPA2 for around $700.

What else do I need to have a good startin system?

I have no intention of buying a subwoofer at this time. Maybe I'll add that later.

Do I need a pre amp to pair with the XPA2? I don't know too much about high end audio. What is the precise function of a pre amp and do I need one? Please recommend one for this set up.

As for the source, I would like to get into vinyl but I will hold off on that for the present. But bear in mind that I would like to be able to incorporate a record player into this system without much trouble in the future.

Instead of purchasing a high end CD player or SACD player, I though it would make sense to get a high end DAC for a computer source like a laptop so I can store my audio on my computer.

Can you recommend a good DAC that would be not too expensive but good enough to get the most out of the rest of the components I have selected?

So far I have, Magneplanar 1.7 speakers, Emotiva XPA2, maybe a pre amp and a DAC for running digital audio from a computer source. Not counting the cables to hook everything up, this is basically what I need right?

One final question. Should I also get a power conditioner to protect my components from surges and also to "clean" the power from my home outlets? I don't want to spend this much money and have my components damaged. If I should get one, please recommend one that is inexpensive.

Thanks for the help.
