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

Best is a relative term in that you need to understand the synergy between the Amp and speakers and pre amp.

Pass makes a great amp, but the key is finding those who have the same speakers and what they use for power.

I have my own bias and budget and those also play a role in ownership.

It is Not a simple answer, yet the journey should be enjoyable as you discover what is best for Your Ears.
