Hegel H160 -> Hegel H390 upgrade suggestion

thanks @audioman58 makes sense. I will try them out and keep you guys posted. Luxman and Pass are indeed very sought after if price is ofcourse not the concern. The build quality speaks for itself.

+1 on a second sub either way, as @soix has stated.  

but do you think a second sub would make that much of a difference when the lower frequencies are directionless anyways?

This is sort of true.  Very very low bass can be directionless.  Try this: stand in your room, close your eyes, and point to the sub.  You can pick out a single sub almost every time.  Having two subs allows the integration to be almost seamless.  I am a REL fan, but you can integrate most subs easily.  First, set each sub's phase for maximum bass response.  They may be different  Then, set the sub volume where you can hear it,  and adjust the low frequencies until they just disappear.  Then turn down the volume until you can barely hear it.  do this one at a time; you may need to go back and forth a bit.  Properly adjusted, not only will the bass fill in the lows, it will more effectively support the soundstage and improve the midrange of your speakers. And they will disappear much more readily.  At least this all did for me.  You may even find experimenting with different sub positions helps.  

@fastfreight I guess I should try that with one sub like you advised and then get the second one as advised. I never thought of adjustment in that sense ever honestly.

REL has a nice little video on sub integration.

@fastfreight thanks will dig it out tonight and give it a shot for sure.
