I installed 4 more E-Mats several days ago (paid for 12, have 10 now installed). I doubled the direct equipment only power panel, doubled the Bit20 (with one on top and one under), doubled the EAR Acute CD player and tripled the pre/phono under. For the first 20 minutes, I wasn't satisfied with the sound, jazz was sounding too forward and just not right. After an hour, the sound calmed down and then I began noticing the difference. First, the dynamics and soundstaging grew bigger. Unusual miking of instruments on one CD had a triangle hit outside of the mix to the left of the left speaker, like it was added later. It was always in the mix within the soundstage previously. Separation of instruments and singers is greater. Percussion and bass are cleaner/more detailed. The music sounds more organic if there is such a phrase applicable to the sound. While I could easily live with 6 E-Mats, 10 are better, just like 12 were better at Franks' place.
The price of an early pressed RCA LS of the the Shafran Shotavovich/Schubert LP has been $1000+ I didn't think my latest CD copy made it sound so special that it was worth anywhere near that. After the first 6 E-Mats were installed, I was thrown for a loop. The CD sounded spectacular. Now I can understand why the LP garners such high prices. It's that way with the several dozen LPs and CDs I've heard since installing 10 E-Mats. More spectacular sound from previously good recordings that did not show their true quality.
