A list of efficient speakers at ~$5K a pair.

OP thats a good move and Fritz speakers are very nice and he is I super nice guy, $5000 can buy a nice speaker in the used market there are a lot out there take your time and have fun don’t forget about Joseph Audio Pulsars if you have enough power.

@paulcreed  Yes, I have always considered the Pulsars as a speaker that would fit well into my room/system when I had a SS amp with the power to drive them. My current SS amp is the Pass XA 25 which I believe would be marginal at best. 

You have a very well curated system. Don't sell the Fritz before you find something you have heard in your home that you like more. You may miss the highs!

@jeffseight  Thanks you. I am in no hurry to sell the Fritz speakers. You are right about the 'highs'. My goal was to develop a system that relied on quality power, not quantity power. Said system best fit my budget. I also believe that the value of  speakers is in how they fit the room and have the desired presentation therein, not their cost.
