Which amp would you choose and why - Pass Labs XA-25 or First Watt F8?

I wish the XA25 had balanced inputs

@aberyclark 

i wished it did too but i was able to use the balanced outs on my preamp and balanced cables by using a neutrik xlr to rca adaptor at the amp.  
sounds better than using rca to rca.  

@avanti1960.

Have you tried just using single ended preamp outs? I would be shocked if using the balanced out and converting to single ended would sound better than just using single ended. Pass is one of the greatest amp designers of all time. If he wanted to use balanced input they would be there.

i live 25mins from Pass Labs. Have been there a few times and given a tour and education at the same time. Great people, even meet the man.  i am a Pass Labs dude!  the 25 will have more bass control with your speakers.  the F8 is their version of a solid state tube amp. that said, the only way to really know is to listen to both of them

Forget about power for a moment. XA25 is a normal pass amp. If you like pass sound (smoothened out, clean, safe & a bit boring), get XA. If you are looking for something raw and true to source, get Firstwatt. It should satisfy your speaker's hunger though. Look for a J2 as well
