I am not sure of your budget here. I recently had a BAT VK300x SE in my system while I had a small issue getting fixed on a amp. I have a all BAT system (51se, p10se super, vk150se's)
I'd consider the Kimber Palladian PK 10 given your sonic priorties. Also, I'd in general, you'll like the Purist Dominus Ferrox rev c. Both will give you extension (The purist better on the bottom and richer through out).
When I heard the VK300 in "my" system compared to BATs top of the line, It more than held it's own. Killer int. amp you have ! But is did loose some of that extension on the top and bottom. I'd recommend either of these 2 cords, buy I'd like the Purist Dominus Ferrox best, the Kimber a close 2nd and closes to your stated goals above.
Also, for top end and air, have you cleaned your contacts recently? That may help this. Also. TURN off you int amp, let it cool. Unplug it. Take the cover off, pull the tubes and clean the tube pins and sockets with your contact cleaner. Be gentle here. This will give a improvement likely.
Finally, what is your BAT VK300 sitting on? Proper isolation really helps the BAT gear and address the exact issue you are raising in your system.
Hope this helps
