Are Pass Labs amps probably the best ever you can buy ?

"At Pass we build amplifiers with excessive output stages, huge heat sinks and massive power supplies. We use the highest quality components in simple linear topologies, assembled and tested with great care in Auburn, California. They measure well and sound great. They are heavy, reliable and expensive."
In my opinion, the only way to go is class A and I'm not sure anybody does it as well as Nelson Pass. Beyond that, Nelson is just an excellent human being that embraces a great life philosophy. I think the thing that makes Nelson such a great guy and engineer is that he finds fulfillment and joy in giving and humbly receives new ideas and approaches to things through that process of giving and interacting with his customers, fans, and DIY'ers. That guy has taught me a lot. His followers have taught me a lot. 
Best amps there are? Tough question. Are his mainstream amps everyone's cup of tea? No. The guy readily admits that some speakers pose problems for amps that he doesn't waste time worrying about. On the other hand, he's designed some amps that are ideal for very unusual speakers. They're all very well built. He puts a very high priority on his designs being very stable and reliable. I love my F5. I haven't heard anything yet that compares to it and there's definitely room for improvement. But I'm sure it's not for everyone. 

One answer. YES!!!! Get Pass Labs and don't look back. I have the X260.8 monoblocks I will never go back to tubes.
Happy Listening

Pass are superb, there is better.
for less, shop around, listen and learn. 
I went with McCormack. —-and no turning back now. 
Im hooked on Steve’s house sound. 
 Passed up a Pass mono pair for the McCormack monos’, could not be happier, your ears will tell you what you like, when the goosebumps hit......you will know. 
Enjoy the hunt. 

I’ve always liked Nelson Pass and his designs but unfortunately I’m tied to a little Dennis Had single ended tube amp driving efficient speakers...I can’t break loose...that new 25 watt Pass amp seems SO cool...but I fool myself into thinking tubes are just better sounding...maybe the SIT First Watt amp...no...I can’t do it...damn.

Take a look at the SIT3. It uses 2 complementary input JFETs to drive an autoformer for voltage gain followed by a single power JFET output actively biased by a MOSFET constant current source. A real damping factor, 200kR input impedance, and a near double of it's output into 4 ohms...it's a real amp with real triodic response curves that makes real power.
