23

My man cave is equipped with a 48" TV. Some of you (my fellow Curmudgeon Societé Generale members not so much) might not think that is very big. Let me assure you, from 6' away, it is nearly IMAX. 

It was an early model. Surprise of all surprises, the speakers are in the front. Wonders of wonders, you can HEAR things, like dialog and such. A TV-wide built-in speaker bar where sounds from the left sound like they're coming from outside the house are included. 

When I got it, volume setting 23 was perfectly adequate - enough to hear everything and not so much that certain Sainted wives would yell from adjacent rooms. 

These days, 23 doesn't cut it. Neither 26, 28 nor any of the 20s. I think the amp must be going bad...can't be my aging hearing.
