Speaker swap or Amp,which impacts more????

I was right where you are. I went with B&W N802s and I thought they were a great improvement, since then, I went from Bryston 4B-ST to Roland M201 and this also enhanced my sound. Either way, there was an improvement. I think the speakers were more but since I sold the older B&Ws I can't be sure. I think the good thing about the N802s, they hold their value like the Bryston amps so you will be fine if you move in a differnt direction.

you have a great system......a swap would be different, not necc better....a powerful sf tube amp if you have to change anything

2bigears, If you have not addressed some soft of room treatment I second the recommendation to start there. Before you go and sell off your line 2, what tubes are you running in there? Changing the the tubes in the middle positions to some NOS makes a world of a difference in dimensionality and bass slam with these units.

I think the speakers would be more of a impact than changing your preamp or amp, and don't rule out room treatments as mentioned above, It seems alot of people put this very far down on the priority list. Room treatments and dedicated lines has been huge!
Happy Holidays

thks all,Gsselling,the tubes are still SF originals.can you direct me to a good set for replace.what brand,where to buy and if i need to change all of them.thks much.
