Question for Merlin VSM/ARS Sonum owners

Hi all,
What did you have (preamp/amp) before convert to one piece Filarmonia ?
Is this Filarmonia sound that good with VSM?
I currently run my VSM-MXe with Cary SLP-05 with Cary CAD-120S (both are Stereophile Class A rated if that matter) - My CD player is Cary 306-200 - Using Cardas Golden Ref balanced cable thru out system.
Wonderful sounding in short -
Now I have a thought of trying Filarmonia to save some rack space (1 vs 3), cable, and $$ as well
I would like to know what you have before ARS Sonum and your comments
TIA
Thuan
