Don, welcome. Since your room is small, the M2s plus the sub should be excellent if the lowest bass can be redirected to the sub. On the bass point, as Ken commented, a description of your setup would be helpful. I'm aware of the Channel Classics SACDs and it isn't at all uncommon for multi-channel SACDs of any label to be 4.0 or 5.0 without a LFE channel. The LFE(low frequency effects)channel was basically created to play explosions, etc. in 5.1 movies that had special low frequency requirements; it doesn't handle the regular bass frequencies from the other channels. There's little or no advantage in most classical recordings(which is what I listen to)in including a LFE channel. On SACD the bass management(sending the lowest bass from the four or five regular channels to the sub)could be done by the player, by a separate device such as the Outlaw ICBM, or by a very few receivers. So, there are ways, even on SACDs, to direct the lowest bass to a sub.
