System synergy or mix and match


I've put together and interesting system....Sonus Faber Cremona Auditor M Stand mounts parred with two REL G-2 subs, Mac 601 monoblocks and Mac C50 pre, Modwright Oppo 105 and Lumin A-1 Streamer with Kenneth Lau PS, all Audience AU24 power chords and high end AQ interconnects and speaker cables.   Thinking of changing to tube line stage and was curious on thoughts out there of sticking with Mac or perhaps trying a different brand.  Seems to be a ton of nice choices out there but I'm also aware of same brand synergy...any input?
Thanks

Do you have any friends with a nice preamp or a dealer that would allow you to audition one? That is the only way that you will know how well it will integrate into your system.
Yes there is something to be said about brand synergy to some degree but look at what the  speaker and accessory Manufacturers are using at shows like Axpona.  Most have an assortment of different gear. Specifically chosen to showcase their products.
If status quo and bragging rights are high on your priority list then go with Mac. If music is your goal, then have fun and experiment. 
My 2 cents FWIW
Thx JD....good call...bragging rights don't enter into it....all about the music.  I have a bud with a rebuilt, old school Counterpoint line stage...we are going to audition that soon.  I see Counterpoint got some nice reviews.  Looking forward to the journey!
Yes, Counterpoint is a good one. I have a fully tricked out Audio Horizons that sounds very good. It has replaced an Aesthetix Calypso and was a nice upgrade from it. The fellow that I got the AH pre from replaced it with an Allnic which is a VERY nice piece. 
There are many other nice ones such as Audio Research Reference series, Conrad Johnson, Cary 05 and more. And then comes the tube rolling.
Have fun and enjoy your trials.
