452 or 601's

Stan.......My MC452 begins with a different prefix. My MC452 serial number is AAT1308. It is possible that McIntosh may have had a running production change somewhere in the production lifecycle. I don't know what that might have been.
 
I wonder what ACF and AAT means? Time to email Chuck

It is turned ON and energized. Gonna leave it on all night and begin its maiden voyage in the morning.

Stan.......If you are using the back panels on your Salamander rack, you may have to remove one so the amp will slide deeper to allow the MC452 handles to clear the door. It's either that or remove the door.

You were right. I have the rear feet of the amp right at the edge of the salamander and only than the door closes completely.

I'm planning on cutting the rear panel to size to fit the 452's protrusion.

Thanks mate!

I wonder how different 452 would be compared with Pass XA30.8 (let's say if the speakers are >90db)?
 
WOW what a difference and I've not even sent any signal to the 452 yet.

The first thing I noticed and this is in comparison to the XPR 5 that I've been using to power my mains until now, is the total and utter complete silence!!!! Just black as night.

The XPR always had some varying degree of buzz and hiss from the tweeters with only power turned on. Not the MC.

Money well spent already [emoji3]

Thanks for all the pics! Mc amps are a thing of beauty, love those big blue meters. I had a 402 and 501 monos. They were fantastic amps.

Indeed. She still has not begun her maiden voyage yet. I will in the morning when everyone wakes up. She's all hooked up though....funny do macs turn off automatically after a while if there's no signal going in? I tried keeping it on all night just to energize the components but it kept shutting off eventually.

On the other hand, I could barely sleep thinking about how good she's gonna sound...

I've got to say....been listening to all the familiar tunes in the past 24 hours and my mind is simply being reshuffled seeking calibration to reality gauged by the sound of music!!! And that's exactly what it is.... MUZIK. MUSICA. Nothing more. Nothing less. I'm not the type to qualm about having to hear every tiny micro and macro detail in the song, musicality and realism is more important than specifics to me. It's like watching a beautiful scene in an Imax movie, you won't have time to capture every detail in your mind but what's important is the beauty of the frame as a whole in that moment where you go WOW!!! And that's what a McIntosh sound is. A beautiful majestic scene that travels at the speed of sound.

On Sundays I like listening to Christian hyms sung in a choir setting. I've listened to the same albums over the years utilizing various gears from Denon to Rotel, Anthem A/V, Emotiva and now the MC452. And as I listen to them right this moment as I type, for the first time I hear the sopranos, tenors and baritones seemingly floating from floor to ceiling. And I have high vaulted ceilings. With my eyes closed, I could literally feel their lips smacking and their breath evaporating. Fantastically close and surreal.

Glory glory hallelujah never sounded so glorious and majestic! Amazing grace never sounded so sweeeeeet.....He leadeth me sounds so righteous and holy holy holy never sounded so.....welllll HOLY.

Keep in mind, the Mac has only less than 24hrs of total play time and it's already outperforming my expectations. Now I'm starting to wonder if these babies are indeed under priced. Great value. American ingenuity and muscle with all the control. Oh BTW, had it on and playing for about 15 hours straight yesterday, barely warm to the touch. Very nice.

Stanly - the 452/2500 combo is excellent. Let me ask, how hard was it to get that big bad boy in your cabinet?

Exciting stuff! Keep us posted.

Thank God for good helpful neighbors. Him and I got it squared off without a hitch. It's a friggin beast!!! I would've needed back surgery if I attempted to do it myself.

Any recommendations of speaker cables that works well with the 452/803D combo that you know off?
