Pass Labs A/B amps vs Class A amp and Actual Power

For me it's probably a mute point; the XA100.5 is most likely more than I can/would spend even at used prices...

All the more reason to make sure your buying what your expecting. Mind you, the same might be true re: doubling down power/halving Class A bias for the amount of Class A bias in the Class A/AB amps.

Let's be clear. The XA.5 doubles its Class A power. The XA100.5 would provide 200 beautiful class A watts before going class AB. This is indicated in the specs on the Pass website. The older XA series kept the output fixed at lower impedences.

Rtn1, that is exactly what Pass told me today. All of the XA.5 amps will double their Class A output into 4 ohms.

Guys, any thoughts on the absolute minimum room width for Magnepan 20.1's?

Stickman51, I would suggest having at least mininumly a foot and a half off the side walls. You could always put the Ribbon tweeters on the inside to avoid sidewall distortion. The space between the 20.1's should at least be five to six feet apart between the inside edge of the speakers. My 20's were set up this way in my old place and they still sounded great, now I have them more then six feet off the side walls and about nine feet apart and they sound even better. Hope this helps.

Remember, you want at least four to six feet off the front wall behind the 20.1's so they can breath.
