Mcintosh 452 vs Pass Labs XA 30.5


Hello everyone, I'm at the Mcintosh house and so maybe part of the answers will be taken for granted, thanks to the desire to try new devices I'm evaluating a transition from my current Final Pass Xa 30.5 to a MC452. Even the pre should be replaced by switching from an Xp10 Pass to the Mcintosh C48.
I use the Totem Mani 2, Audio Physic Scorpio 2 and Tannoy Eaton speakers in a listening environment of around 20 sqm at low and medium volumes.
I would like some advice from those who have had the opportunity to try, comparing these brands and the good interface between the coupled MC 48 and 452 and my speakers.
Thank you.

Having owned both imo Pass labs blows mac out of the water .A giant move  backwards
Apples and oranges...but for the Totems the MC452 will be a night and day improvement.  Others, not so much.
@missioncoonery so you had a 452 and a XA30.5 and the Pass “blew the Mac out of the water”?
kinda hard to believe, but if you say so then ok. It’s all pretty subjective if you ask me, but whatever 
Why do my posts all have a little snowflake-like icon on them? Is it because I don’t have many posts? Am I on probation or something?
I have owned the Mac 402 ,452,Pass labs x150,x150,5,x250,5,x250.8..all driven into various speakers including the Dynaudio confidence line (which if not mistaken the Totems use their drivers,not positive).Both the mac amps imo are slow with less dynamics,very tubby which has been a long criticism of them..Plus Pass has a better, much better customer service which is a big deal to me.So much i would never buy McIntosh again as i had big issues with them and warranty.
