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.

Totem Mani2 speakers are actually not an easy load
Not correct.
They are an easy load, they are just not efficient 80.7db, which means they need watts rather current when played loud.

" I calculated the Mani-2's B-weighted sensitivity as a very low 80.7dB/2.83V/m. No wonder it didn't go very loud with the low-powered 15W Cary  Cary CAD-300SEI amplifier, as delightful as the sound was."

Cheers George

Let me address my customer service experience quickly.I had an issue with a new Pass amp.Nelson called me personally,worked on my amp personally,took it home and listened to it an entire weekend before sending it back..McIntosh refused my warranty card when I sent it in because even though i had no dealer within 100s of miles,I purchased from an authorized dealer an amp over the phone and had it shipped.Mcintosh will not recognize warranty unless you go directly to the store.On the phone they are the worst company i have ever dealt with.Rude is being generous. One would think after dropping $4500 you would get some type respect from a service rep.I would rather go without a stereo before ever buying anything from McIntosh....having said that Mcintosh imo is slow,colored,bass tubby in comparision to Pass. Mcintosh is like taling a knife to a gun fight

So you bought a brand new 452 for $4500. And the dealer shipped it to you, which is goes against McIntosh policy/dealer agreement. 
I would question the dealer as to why they shipped the unit when they know this isn’t allowed. And you bought the amp for about 50% off retail. Sure it was new?
i have owned many Pass amps. I agree that they are an awesome company with excellent customer support

Not looking for an argument but whatever wording you want to choose your advice was not appropriate. I know those speakers and 30wpc, class A or otherwise, will not be a good match to get the best sound out of them, even in a moderate size room. They’ll sound okay but nowhere near what they’re capable of.

tlong1958..No I bought a MC402 back when it was the latest offering..Pretty sure it was 4500 ,maybe 5500,I don't remember what it was but I paid retail plus about $150 to ship it UPS...the 452 I bought much later used and dirt cheap only to flip for profit, which I did.I would never have Mac in my system after the 402 disaster.So I battled the factory and the dealer at that time and the only thing I was promised was from the dealer that if I ever had a problem contact them.I did wait long enough and sold that amp..but my story is true.
