Thanks for all the replies all - sorry for my absence over the last few days...real life got in the way
Anyways, there was a question earlier in the thread that asked what kind of wattage I am looking for. While I don't have an answer specifically to that question, I can describe the room and listening levels to answer this in a (I hope) roundabout way. My listening room size is approx 20' wide x 40' long (although my listening "space" e.g. office takes up approx 1/3 of this room). I do I have some flexibility in terms of placement of the speakers / listening position, and I am not opposed to moving the speakers for listening sessions, and moving them back to their wife approved home afterwards. Listening levels will be what I call average - most days will be soft to medium, with the rare occasional cranking session when wife/kids aren't home and I am feeling frisky. I also have a seperate headphone setup, so will likely just transition to that when I want to crank up the volume.
My current speakers are the KG4s, but do plan on upgrading down the line after I have a chance to listen to some of the KG4s bigger brothers (mainly the Forte II and Forte III, but also will be plan to eventually audition the Heresy speakers as well). My sources for my system will be Vinyl (have not yet acquired my turntable, although currently looking at the Technics 1500c) and a Schiit DAC that will play double duty in my headphone setup.
Hopefully all of this helps - I do appreciate all the recommendations (please keep them coming!), both here and in PM. The Fisher 500c Jimbo mentioned above is definitely in the running, but recommendations have also been made for other varieties/brands, including the Marantz PM8004 that I am going to be auditioning next week, that have given me some options to think about.
