A audiophile is someone who seeks out the best sound from recorded music, the brands you mention are not high end and are not considered high performance they are mid fi at best.
B&W is the only brand you mentioned that makes speakers that are somewhat respected by the high end community.
Second recievers will never produce high end sound, there are to many compromises in sound quality to be considered high end. There are a handful of receivers that are ok sounding, use reasonably decent parts, but still the better option is integrated amplifiers or better yet separate amplifiers and preamplifier.
The only place to purchase high end speakers and equipment is your local independent high end audio video dealers, they also have the knowledge and experience to design high quality systems.
Its really endless what you can spend for a truly state of the art high end audio system, but there are some exceptional sounding budget gear you just must choose wisely.
Vandersteen, Magnepan make some great budget speakers, but its important to know that even the best speakers hooked up to cheap equipment will still only produce mediocre sound. Speakers are only as good as the equipment driving them, the detail comes from the front end, speakers can only reproduce what they are given, so the equipment is equally as important.
A good book to really learn what makes a high quality system, is THE COMPLETE GUIDE TO HIGH END AUDIO by Robert Harley, it is well written, very informative and will give you a good foundation of what to look for and how to achieve truly high end sound.
