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

Pass is one of the top choices among the solid state amplifier.


But if you listen to mostly Jazz, I recommend you to try tube amplifier.

The Jazz voice will sound magical with tube amplifier.

You did not specify your speakers.

If your speaker is efficient you can try small power SET amplifier.

But if your speaker is not efficient you had better try out PP tube amplifier with more than 100watts.

If is always important to check the synergy between amp and speaker by auditioning at your home.

Vitus, a Danish company, has a lovely series of amps which are often mentioned in the same breath as Pass when looking at the best in solid state.   Their small class A integrated SIA-025 has become something of a classic here in Europe. 

There are many good amps. I am No expert but I have liked Mark Levinson during demos as well as Devialet.

No other company I know of takes care of their customers like Pass Labs. You can call them at any time and discuss your entire system. They will cheerfully talk to you. When it comes to repairing something NOBODY compares to Pass! Their philosophy is not to charge for repairs more then
necessary. I had a Pass Labs X1 preamp for years. It finally needed work. It was of a vintage that they needed to replace several circuit boards in order to facilitate the repair. I braced myself for the bill. Including a new shipping carton they charged me $125.00!!!!! Insane but great for me and all who decide to be Pass owners. Good luck. Joe    

I have owned many of the Pass products There is no better SS amp
made anywhere. And the customer service is second to none. You will not be disappointed.
