All are great. I have been a fan of Krell and McIntosh for years. But you really have to listen for yourself. One of the best systems I have ever heard in the last 20 years was an all McIntosh system. The funny thing is most "audiophiles" don't consider McIntosh "high-end". The bottom line is you are the one who has to live with the equipment so give them all a listen. If you can't listen to all of them make your choice on which one you can hear. The best thing would be to take an amp home for the weekend and give it the run though.
