FWIW, I drive speakers with lower sensitivity (89dB) yet slightly higher impedance (6 ohm minimum) with XA60.5s and plenty loud. But I admit I have seen the needles twitch. I'd be all over those XA160.5, personally.

At 36 amps peak, I can't imagine why it wouldn't edge out the
XA100.5 in this regard.

This discussion is about some very serious equipment. Just how big is the room you plan to install your setup in? As many qualified individuals have stated previously the majority of the music material will never use more that 10 watts of output power. Just one more reason why SE tube amps are so popular.
Since this is the DIY audio forum I suggest you find a good layout here and build your own. Nothing sounds better than home grown. I really liked my massive Mcintosh setup and was totally pleased with the quality of sound. However, I also like my Leach clone DIY amp and all the extra money I was able to stash away when I sold the Mac gear.
Honestly you will enjoy building and learning. The overall rewards far exceed the name plate heading on any amplifier especially when the name on the amp is your own.

Do not tell me none of you guys have never been swayed by a nice looking YOUNG curvy saleswomen.

i have the Pass Labs Xa 100.8 driving Wilson Sasha mk i.
alos been wondering if i should uograde to Xa 160.8.

But Xa 100.8 max output current is 40 amps. this is better than the Xa 160.5 which has 36 amps.
Therefore the Xa 100.8 should control the Sasha better than the Xa 160.5


Is this correct Mr Nelson Pass?

The current limit figure here is pretty arbitrary and based on the value
of zener diode protection. I wouldn't worry about it.

You do realize that 36 amps into 1.8 ohms is about 2300 watts...
