Short List of Amps I prefer over the Pass Labs XA25 or INT 25

I know this is a little off topic, but is there supposed to be a difference in sound between the XA25 and INT25?  I was reading some reviews and they are talking about JFET, Vertical FET, BoboFET, but they don't really explain what it does, or why it's better.

For those of you that are quoting text, are you just clicking the " button then copying and pasting the text from their post?  Sorry, I'm new and have been reading more than posting.

jw,

Sometimes I think the XA25 sounded better than the INT. I never had the
two at the same time. The INT is still a very good product and I am happy with it. AVA has a new Mono Block amp that a buddy of mine
loves better than Pass with his ML CLXs. 

That would be these.

They're very good.

Thanks for the reply.  I was looking at a lot of amps and amp/preamp stacks and at the end I purchased a new First Watt F8, since it's the latest from Nelson Pass and comes with a full warranty.  

Those monoblocks look awesome, but I just put in an order for a BHK Pre-amp, which seems to have a history of working best with a BHK amp... and by working best, I mean it will have less quirks, noises, issues, etc... A lot of people seem to keep the BHK pre despite these little quirks, so it was a leap of faith, since I will be running it with my F8.

Part of the fun is experimenting with new gear, hopefully I won't regret this.  I want to try those monoblock amps now!  Thanks for the link @twoleftears 

Touche Atma!  Well said sir!

RE the Spectral question. I heard them in May of 21. 
None better.
