Subwoofer for two channel system


I love my stereo system. It includes the following:

Rowland Synergi IIi preamp
Rowland M201 amps
Cal Audio Labs CL-10 multi disk
Meridian 588 CD player
B & W N802 speakers
Reimyo DAP-777 DAC

I am very interested in adding one or a pair of subwoofers to the system but I do not want to mess with the sound too much. Just add a bit bass to make it perfect. Any suggestions would be greatly appreciated.

Hi,

I'm currently using Totem Lightning for my two channel system wand I'm satisfy with the soundstage.

I also have to of VSA VRS1 subs with my VR4 Gen III HSE. Sound awsome, you can't go wrong with it. Good luck
