Pass X-250.5 or Plinius SA-103

If money is an issue, I am downsizing and going back to the Pass Labs Aleph series. Still great amps with many models to choose from. I have been running one Aleph 3 with my Audio Physic Virgo IIs with great results (30w into 8ohms,60 into 4ohms). I have another one the way so I will be verticlly bi-amping for extra headroom. My Virgos are a tougher load than your Nines...4ohms at 90db. I am downsizing but got a chance to hear a Pass X-0.2 in my system and put my X-1 up for sale (big upgrade). My favorite the Aleph 2 is for sale on Audiogon....I do not know the seller! They are not the biggest mono blocks in the Aleph line but very sweet!

The Aleph 3 is single ended. I think the other Alephs were single ended or balanced (with the exception of the 0s ?)

I think if you like the Plinius amps, to my ears it is similar in presentation to both the the Aleph and the X series Pass equipment, depending on the position of the bias switch. I had the SA-100 and would compare it to the X-150 Pass A/B design. When switched into high bias class A very similar to the Pass Aleph 4...but I found the Aleph to be the most musical to my ears...a little magic!
