I love marantz amplifiers, they are really well balanced and sound excellent for PCM stereo as well as DD, DTS etc.
Good speakers will make all the difference in your system. If you specify your speaker budget we can offer some more specific products to try.
For foreign manufacturs I like B&W, Energy but you can get batter bang for buck with local made products of excellent quality and sound for every possible budget.
I personally like VAF (
www.vaf.com.au) the best, but sound is a very personal issue. Make sure you spend at least 1 hour listening to what you are going to buy when you narrow down to the last 2 or 3 sets of speakers. Some speakers sound good for 5 mins but wear you down for exteneded listening.
Some other good sites are

www.audioreview.com is ok for info about hardware (amplifiers and American speakers etc)
