Try running a full site search of "Belle Klipsch" @ audioasylum.com and you will then be able to read quite a bit about your speakers and tried/true amplification.
Only agree with the advice given in two of the above posts (numbering seven as I post) based on personal experience with SET amps and my advice is to visit Audio Asylum, spending your time @ first using the search functions.
