System matching can be difficult...

I think I have a well matched system and I feel no need to upgrade or change any componets

simple but good
Its a start

A sensible solution is to go with a company that designs and manufactures with system matching as a guiding principle, particularly in the source through amplification chain. Unfortunately, VERY few excel at all links in this chain. One company that does is Naim. If you're anywhere near a Naim dealer, give the gear an audition. Speakers being the most personal of audio components, another manufacturer's speakers might be more to your taste. For instance, ProAc does very well with Naim components upstream. Good listening!

Audio Note was the answer to my system matching problem.

I am embarrassed with all the transactions I have on Audiogon because I didn't know about AN gear.

Use this forum to your advantage by searching the archive and seeing what other reputable members are using with your individual components. If no information is found, ask. Also, call the manufacturers. For example, If you own a particular type of speaker, call the manufacturer and ask them what they recommend for amplification. You may want to go to a show...perhaps RMAF in Denver and see what other folks are using with your gear. Instead of trial and error, ask first. That being said, trial and error is a good thing; as you have found out it is a learning experience, albeit an expensive one.
