What Horn loaded speaker/ speaker system for $10k'ish and under
Perhaps a Horns Mummy, if the looks are acceptable.  Incredibly smooth mids and highs, strong bass from a 12" Beyma.   No need for a sub, at least not for myself.  Soundstage is incredible for this price ($3k used), both vertical and horizontal.  ... 
SET amplifier (for AvantGarde Duo's-original) recommendations

Great review on HORNS Symphony Loudspeaker for you "aficionado's" of horn speakers
Thank you for the response, nepfotos.  I have a chance to purchase the Symphony 13" at an extremely low price, but I'm just waiting to make the jump.  The dealer I purchased the Mummy's from said the Symphony's provide a "beautiful" sound.  With o... 
Which pair of speakers changed your Hifi life?
Horns Mummy by Autotech, followed by Horns Atmosphere MK2.  Similar to Danager, I didn't realize the potential of horns (when done right).  With the Mummy's, I learned what a large soundstage is all about, along with HF clarity, clean bass, speed,...

Linlai E 6sn7 tubes
@ram18. The PSVane UK 6SN7's are bright, clear-sounding tubes.  IMO, they're not a "musical" tube, if that's what you're looking for.  I'm currently running them in a Finale Sesto Elemento FFX (6V6-based amp) running a pair of Horns by Autotech At... 
Horn speakers are really bright?
I have a pair of Horns by Autotech Atmosphere MK2 and find them soft.  Extremely detailed but just a little too soft for my liking in my living room.  However, for smaller rooms, I'd say they're near perfect for my needs.  No fatigue or harshness ... 
10k Towers with biggest soundstage?
Horns Mummy by Autotech.  Conversation starting look, which isn't for everybody though.    
Suggestions for an integrated upgrade please
I'd email Frank at Finale Audio.  No matter your speakers or other equipment, he'll point you in the right direction.  I myself use Apple TV with their lossless and digital master recordings.  But my DAC is a Hifi Bluetooth receiver too.  Best of ... 
The Most Philosophical Song You Ever Heard
One that comes to mind is Pink Floyd - Time.   
Great review on HORNS Symphony Loudspeaker for you "aficionado's" of horn speakers
Late congrats on the purchase.  Any input on how these compare to the Mummy's (which I have)?  Seems like the horn adjustability can come in handy.  Thanks
