However, in this day, you could not get this system for that money. I agree with others that an integrated amp is your best option. But of course, there are many that you could not buy for $5k. I have heard the Exemplar eXception integrated amp but it costs %$5.5k. The LSA Statement integrated amp can now be had for about $3k used and is also quite good and more powerful.
What you lack today is the many dealers that used to be around where you could hear equipment. This seems to be a result of the internet and buying directly. All that can really suggest is going to local shows and reading reviews by those you trust. Also were there any consensus among those posting, you might get some guidance.
