Pass Labs Speaker Choices

Magnepans and YG Acoustics.

I got good results with the Pass XA25 and Tekton Lore Ref BEs (about 89db free air sensitivity). 
 

Great amp but I wouldn’t recommend it for speakers any less efficient, unless one has a small near-field setup.

Can’t comment on other Pass amps but it’s interesting that since I’ve listed my XA25 for sale, multiple potential buyers have told me it’s the best sounding of all Pass amplifiers. 

I currently have Pass INT-150 and Martin Logan Montis.  Like that pairing very much.

The first Magnepans I ever heard were driven by a First Watt amp, I forget which one. The owner thought it showed that a good power supply and solid engineering provided plenty of juice if you weren’t aiming for rock concert sound levels. I took it to heart and now have a living room secondary setup of a diy First Watt M2 driving Maggie MMGWs with a little Martin Logan sub. It’s a sweet sound, but again, pretty modest sound levels and mostly acoustic music.

Nelson Pass uses Tannoy speakers to voice his amps and I can verify that the Cheviot is an outstanding pairing with a Pass INT 25.
