McIntosh decisions

I have the mcintosh c 12000 driving  several monoblock mcintosh with a xlr splitter with out any problems. Mcintosh has powergaurd as mentioned that protects it on bad voltages and sometimes puts it in limp mode. Also it has clip protection that won't let the amplifier clip. You can get on mcintosh  website and they list certified repair shops and there are plenty. I do also have the mi502 that is 4 hypex modules class d 500 watts in 8 1kw in 4 ohm. I have several brands but love my mcintosh  blue meters the best,well built and heavy stable to at least 2 ohms.enjoy the hunt and the music

My experience with preamplifier / amplifier combinations vs. integrated amplifiers is that the separate chassis systems sound lower in noise because of the individually isolated power supplies but the big plus to my ears is the life like excitement of 0 to 60 off the charts speed and dynamics.  

Once I went to separate chassis systems I stayed that way.  

Currently running a newer mint C22 MKIV retro look tube preamp and a new MC312 solid state power amp and loving the sound.  

I run a C2300 with MC601's mono blocks and I love that combination. The C2300 made my system sing. 

Ive owned Dynaudio Contour speakers (rated at 200wpc) for 25 years and recently I was able to obtain a second McIntosh MC352, I run these in mono for a minimum of 700wpc! Yes I have to be mindful of the volume knob, but the sound is much better, more impactful, more defined, better detail and improved dynamics. I never thought having so much power would be needed or wanted, but now that its hear I can never go back.  So I would say to the OP that separates are the way to go. But make sure your passing on the integrated for the right amplifier ...The MC462 is one of those amplifiers you keep forever and maybe even get another:-)

to add as to why a preamp in the mix adds additional dynamics and lightning fast response is that it has additional gain being powered by an additional power supply and additional storage capacitors.  this adds the ooomph to the sound for both minute changes in pace as well as fully blown crescendos.   

most integrated amplifiers have a passive (zero gain) preamp section (except for phono stages).  

the sound of an integrated amp tends to sound less dynamic and more laid back when compared to a properly matched linestage + power amp system.
