whats the best addition u have bought for system

Move speakers at least! two feet from back wall and three feet from side walls. Put bookshelf in the corner or along side the wall by the speakers and maybe some heavy big pillows in the other.

The NAD may help a little however I would invest in a better / more powerfull integrated for the Gold i's, maybe 100 watts. Here on Agon for $1000 or a bit more sometimes less you can get a good sounding integrated that has decent bass control and overall good sound. Arcam, BelCanto, Musical fidelity are brands that consistently make pretty good stuff.

I went through many pairs of speakers thinking they were sloppy in the bass dept and one dimensional untill I upgraded and went from a reciever to a good integrated.
Then I got a good CD player and impoved things even more..

Then I got better speakers, then better amp, then better CD player then better speakers then amp then cd player then better speakers.

then I finally found music I liked.

Switching from solid state to tubes . That made the music come alive !

Flyin2jz; ditch the receiver and get an integrated amplifier . An integrated amp is a receiver minus the radio and usually of higher quality , especially in the power supply (quite important) and amp portions of the unit . Then work on your speaker and listening positions .

Good luck .

Upgraded my old NBS cables to the IV series.....major improvement....thanks Walter.

The best auditioned I ve ever enjoyed ,hooking up, my
