Tube amps under $7500

Raven Audio all the way! Their tube amps and selection of NOS tubes are second to none. I wrote a full review on my journey to find the best tube amp here (spoiler alert: Raven Audio blows Prima Luna and McIntosh out of the water). 

If your speakers are 88+db, the Black Hawk has more than enough power and sounds fantastic. If you want a little more head room, go with the Osprey (which is the one I have and love). 

Either option comes in below your price point and ships with NOS tubes that can be tweaked/upgraded to your liking. 

Good luck!

Unless you are dealing with a long cable run (say 15ft or more), you will spend a lot more money and never hear the benefit of balanced inputs. It's easy to get obsessed with specs, but how the amp is voiced matters WAY MORE than its specifications on paper.

Don't sleep on Raven Audio ;)

Good luck!

@ditusa , the article you posted mentions several times that balanced operation was developed to make super long telephone line runs possible and adopted by the pro-audio industry for long cable runs between the mics and subsequent electronics. Sounds kinda like what I said in my post. 

Your article is also chalk full of vague generalities like this, "Balanced lines offer advantages even if the connection is only 6" long, although it is also helpful for longer distances."

While this may be technically true, so is saying that spitting into the ocean raises its overall volume of water. Any minute "advantages" a balanced operation has on a sub 15-20ft cable runs are, in most cases, inaudible and nowhere near worth the huge additional cost. Getting an amp that sounds great is priority 1. That amp having XLRs is a distance 4th place on my priority list.
