Depending on your expectations of "low level" listening, virtually any receiver/speaker combo can be just as good for low level listening as it is for "normal" listening levels.
The problem arises not with the hardware, but within our ears. At low sound pressure levels, our ears are more sensitive to the midle ranges and attenuate the lows and the highs. This is why all systems sound "tinny" at low levels. The hardware is doing just what it does at higher levels, but we simply can't hear the frequency extremes.
In the good old days of stereo, a button called "loudness" would boost the lows (and sometimes the highs) at low levels to compensate for this deficiency in out hearing.

This magic button seems to be missing in today's HT gear but you can get a similar effect by boosting the bass control. I don't even know if this exists in modern stereo gear, either. My most "modern" stereo tuner/preamp was made in the early 90's, and it has one.
