Now, I'm confused.

+1 mattmiller! Changing to an Adcom GFP565 preamp would be a beneficial upgrade! I also think that your phono cartridge (unspecified) is a limiting factor. I have found mc cartridges to be superior to mm types. I recommend a Denon 103R as a very good low-cost mc cartridge that will work well on your Dual 1019 TT.

Regarding fuses and speaker wire - neither will give you an improvement in sound quality - regardless of what the "golden ears" crowd says! I have been in this hobby for 40+ years and am appalled by the level of "magical" thinking about wire (and now fuses)! Hucksterism to entrap the gullible!

For the most life-like sound in any room the Ohm Walsh's beat the competition hands down! I have a pair and they do indeed produce a 3-D image superior to any box speaker. And from ANY spot in the room - uncanny! Mine are the Sound Cylinders.

All recordings are artificial and many (particularly multi-tracked rock and rap) are far from the "sound of musicians playing in a room"! What many prize in a stereo system as "soundstage" is often an illusion caused by wall and floor reflections! 

Anybody remember the AudioPulse reverberation device? It allowed one to dial in various settings: "small club" all the way up to "cathedral"! It contained a two-channel amp to be connected to a pair of speakers behind the listener. And it gave surprisingly good results when used judiciously! This was back in the mid-70's before HT.
