Fritz carbon 7SE MK 2, Upgrade

I would like to thank the following for your help and expertise that I don't have, or would like to. SOIX< THRIFTYAUDIO<JASTRALFU AND CHAYRO.  All had a lot of great advice. Don't really understand the sweet spot ref: on the ATC's?  I may adjust the crossover a bit as suggested, the second sub in this room would be great, just don't have the room.  Like I said,will never sell the FRITZ, they are that good, at least in my situation with rock and roll. I am not in a great hurry, just getting older as I speak, just very curious!  Also wondering if a Joseph audio perspective (USED) would  be a giant step up, overkill, too much for the smaller room, or maybe Nirvana??????? Thank again Robert

eric_squires/zlone   thanks also. Everyone has the voice of reason, but me. The phrase, NOT BETTER,  BUT DIFFERENT strikes a logical cord!  My  current ATI amp has the current and power to drive most anything. ATC has always intrigued me, but, the Joseph audio has also.  TAD does also, but, my wallet says differently.  Used should open some doors,maybe. I'll keep all posted. Robert

Just doing some soul searching tonight. I have to thank everyone, some excellent points, some profound! I have been tempted at times with a tube integrated, but, the tubes just scare me, SS has been good to me. In my main system, my amp which I will never sell is a Pass X-250.8  and it drives a pair of Specialty  Tekton Encores upgraded.  

One post that really intrigues me is the suggestion of ATC 19 or 20scm. I called Sound Approach on SOIX suggestion (coincidentally same place I bought my ATI amp) their 10% savings is almost over, as tariffs will raise it 10% on Monday. Their ATC 20 new would be 5849, regular price and 10% more Monday.  The ATC 19 is something that intrigues me w/o a huge outlay, also maybe finding a used pulsar, non graphene.  All posts have been great, Thank you Audiogon too. 

After espousing on my Current FRITZ Carbons, and reading@ rammerjammers  post: One word comes to mind that YOU ALL HAVE MENTIONED! Directly or in directly!

QUANDARY!

@larssman  Couldn't agree more. Fritz and I have spoken a few time at length. Very nice guy, regular type, for what that's worth. We both are the same age, and grew up during the muscle car era. We talked for hours on that topic alone. We have a great deal in common. Very easy guy to talk with.  You appear to have the same qualities. Glad you enjoyed your time with him, not to mention the speakers. Thanks for sharing. I live an hour outside of Nashville area towards Knoxville TN. Robert 

I will keep all up to date, Thank you. After listening to all (very welcomed) comments, it is a very sobering, complex, thought process.
