replace Mcintosh with Luxman

The minute I made the switch to the Luxman I heard a boost in bass.  Its my opinion the Luxman are better than the Mcintosh  in every way.  I was using a Lyngdorf mp60 a/v processor for movies and two channel.  I currently got the Linn Climax DSM and Magico S7s and moved the S5s in the back surround position.  For the money I don't think the Luxman can be beat.  Jay of Jays Audio Lab did a review of Luxman on you tube that I thought was accurate and influenced me to switch yo the Luxman.  

replace Mcintosh for Luxman good idea or bad idea? all replies welcome thanks.

magico s5 mk1

SQ huh?

My apologies I am considering m900u amp and not preamp.  The plan  is for two Luxman m900u (in mono mode) for the Mcintosh.  
Thanks to all for the input it will help me decide.

For those interested I decided to go for the Luxman amps(2)  In regards to the Mcintosh I found them to be almost painfully bright sounding in the higher frequencies.  I spoke to a dealer who told me his store has had both amps hooked up to the magico M2 and in his opinion the Luxman magico combination was superior.   I guess I will find out.  In regards to crusty coot concerns switching the M900U into mono mode your opinion is appreciated.  I have done all I can short of demoing the Luxman, which is for me is impractical because I live in Alaska.  For what it is worth Jay of You Tube's Jays audio lab indicated with some stereo  amps switching from stereo to mono was disappointing but that was not the case for the M900U.  Again thanks for your input.
