Feel free to talk me off the ledge

My friend, you are not nuts you have been made aware of a different sound quality of speakers. The depth, height and technology of a speaker matters greatly. My suggestion for you would be to explore the Heritage models further. Something relative about the sound quality of the Klipsch made you stop and take notice, which was most likely the clarity of the highs and midrange drivers. However, the speakers you listed as replacements have lower hertz frequencies than the Klipsch you purchased, not to mention your klipsch project considerably lower from the ground. The Forte IV or the Cornwall would have you wondering for certain.

At this point, however, I cannot imagine you ever being satisfied with your listing space now that you have the knowledge and ear for more. So go for it and be satisfied.

All the best

@doyle3433 Will your dealer let you take the demo units home for a quick listen to avoid having to open a sealed pair?  Back when I had dealers near me I would hang out on Saturday afternoon and take something from his consignment stock, returned or demo home and bring back Tuesday as he was closed Sunday and Monday.  It gave me a nice 2 or 3 days with the gear with my system.  I do miss those days.  

I've heard the B&W 800 and 801 Diamonds with dealer-matched expensive electronics plenty, and whether we call it 'fatigue' or not, I do not like those diamond tweeters, great hardware or not. My ears tell me to turn it down or off, not good.

I still think different speakers' tweeters sound different, that's all, some better to me, some not.

Try the BRXs and give us a good report!   grin.

I have lived with Heresys. As you mentioned, that tweeter will drill a hole in your brain.

You have a lot of good suggestions. But the bottom line is how the speaker performs in your room with your system. It is especially vital that your amp mates well. And really has a SQ that sound real to you.

I have been very impressed with the Fyne line. Those designers have taken the blueprint of Tannoy and taken it to a new level. And if you like horns, the Voti are a great choice and not as sharp as the Heresy.

What do they like? Did they even listen to the BRX? 

I guess both John Atkinson and Herb Reichert are deaf or hard of hearing, because they both liked the BRX very much.
