Sometimes when you make a significant upgrade in the Naim electronics, you will find that the previous locations for your speakers are no longer the optimal ones. I would urge you to experiment a bit with speaker placement before you come to any conclusions about your electronics. Moving speakers a bit closer to the wall behind them often increases the apparent bass performance, by setting up more of a sympathetic room response. This might help better integrate the higher frequencies in your system. Or you may find that the speakers sound better when moved further away from the rear wall. You really have to experiment to find the best balances; for your tastes and for your system.
