I buy a lot of last year Demos & trade a lot with a Stereo Club
Goal: Full range detail with good transparency, sweet mid/highs due to the 2 electrostatic panels, & a tight clear bottom end due to the 6 ten inch woofers.
Limits: The Martin Logan SL3 speakers are an electrostatic panel hybrid which can limit the musical soundstage to either a small to mid-size sweet spot depending on the room acoustics. I have opened up the soundstage by placing 2 subs at the corner postions of the listening room. During listening sections, I toe-in the speakers a few inches to focus on the detail of the music, but if I walk around the house or out in the yard, I turn the speakers parallel with the back south wall to fill the house with music.
Room: 18.2 ft W x 16 ft L x (8 to 20 ft) H
Main speakers placed 4 ft away from south standard 8 ft tall wall facing north to 20 ft tall stairway. Concrete floor with full carpet
Music: Broadway, Classical, Film Scores, Folk, Jazz, Rock, Opera, & World. In other words: almost everything but bubble gum, extreme pop, ultra negative, or rap

Bought a 2nd AudioPrism WAVEGUIDE & placed both on the power cords of the Martin Logan SL3 speakers. In the near future I plan to buy 2 Synergistic Research active shield power cords to use on the Martin Logan SL3 speakers & place the AudioPrism WAVEGUIDE on the balance interconnects from the pre-amp to amp. That way any interference will be cleaned up before being ampfied. Debating on rather buying a 2nd Richard Gray 400s for the other side of the stereo or go for a PS Audio Ultimate Outlet to power the Synergistic Research active shield power cords.
System edited: Move the main Martin Logan SL3 speakers from 3 ft 3 inches to 4 ft away from the back wall to increase soundstage & to place the Synergistic Research speaker cables with the Music Hall Cable Elevators Plus away from any power cords
I just received the above items & here is the first report:
I thought that the AudioPrism WAVEGUIDE came as a pair, but it was single. Therefore I wont use it on my power cords to the Martin Logan SL3 speakers, but on the Sony XA7es CD player. This is because the Sony XA7es CD player power cord can't be removed. The center hole for whatever gets put in the middle of the AudioPrism WAVEGUIDE is too large for the normal power cord of the Sony XA7es & too small for the Synergistic Research power cords. My first reaction is: too few with too little adjustments for too much money.
The Extreme Phono NONE FELT MAT/STANDARD is very interesting. I removed the normal felt mat & palce the Extreme Phono NONE FELT MAT/STANDARD in it's place. The new mat holds the LP in place while playing & I has to turn off & stop the record player before taking the LP off. A little slower starting & stopping normal LP playing but I think that extra friction & less static makes up for it.
I placed the 2 MMF Music Hall CABLE ELEVATORS PLUS on each speaker cable & used the enclosed rubber bands to hold the cables down. I haven't experimented enough to hear any difference in the sound, but at least the speaker cables are away from the power cords.
I just bought 2 AudioPrism WAVEGUIDE to go on my power cords with the Martin Logan SL3 speakers, 1 Extreme Phono NONE FELT MAT/STANDARD to go on my Rega Planar 3 turntable, & 8 MMF Music Hall CABLE ELEVATORS PLUS to uplift my Synergistic Research speaker cables from off the floor. This is going to be my 1st expriment with tweats. Any buddy have any experiences?
