$7000 preamp vs $700 receiver - Is the difference THAT significant?


Current setup:
Marantz SR5005 (AV Receiver) + Peachtree Amp 500 + BluSound Node 2i + GoldenEar Trition 2+ = Current Setup

I'd like... no, want... no, desire... to add "Blue Meters" to my setup.  McIntosh haunts me.  For dozens of years.

My quandary:
Acquire a McIntosh C52/53, maybe C2600/2700... vs something like a Marantz AV7705 (or AV7706 appears it was just released).  Yes I know I'm comparing brie cheese and cheddar.  I'm more concerned with the notion that I can get "as good" sound out of that Marantz preamp, as I can from those McIntosh units... (ignore the multi-channel notions for the moment)

Is my sonic happiness "that much better served" by a McIntosh $7K unit vs a Marantz $2-3K unit?  How much difference can I expect?

“Nothing Else Matters”. Why does Qobuz have loads of  Metallica but Tidal has zero?  Sucks big time.
Theory of Relativity at its best.
Took my bil into one of our stores years ago so he could hear what a 100K system sounded like. Mostly ARC stuff thru big Wilsons..
He sheepishly turned to me and said "It sounds like my Bose but not quite as good."
Yes, big difference.  You could go from a $700 avr to a $700 preamp and there’d be a big difference
OP, get a Mac tube pre-amp. You want blue meters, so get the blue meters. It will be a huge sonic upgrade for you and you'll have a nice piece of gear, maybe for the rest of your life. The Peachtree amp is adequate from what I read but if it was me, I might hide that amp on the bottom shelf. You will not be disappointed.
