As I discussed above, initially I setup the SMS-1 using a main speaker high pass crossover of 80 Hz 6 dB (set in my Theta CB3 menu) . But especially when I played some multi-channel SACD, I noted that my bass seemed sort of to lose some of its life, that the music clearly moved me so much more before engaging the EQ.
Then I setup the SMS-1 using a main speaker crossover of 40 Hz 6 dB. NICE! Multi-channel SACD as engaging as ever - thought it was perhaps better than before, but really didn't do critical comparison yet, just enjoyed, using this setting for all of my music, tv and movie formats.
My audiophile Psychologist buddy Lon Grushko just came over. I showed him how easy the SMS-1 is to setup.
I decided, as we re setup everything, to run main speakers full range with no crossover.
Interesting. We set up the SMS-1 from the sweet spot front row center leather recliner spot, as before, but this time main speakers with no crossover, run full range. Then I took microphone over to other five recliners, and to the very back of the room behind the last row of recliners. WOW! The SMS-1 on screen graph showed very little difference
regardless of room position of the microphone. No wonder my bass has always sounded so similar throughout the room!!
Then I put on some multi-channel SACDs, specifically, Steely Dan Gaucho and a jazz sampler disc from Telarc
Heads Up label. Immediately Lon, who has spent a number of hours listening to my system especially these discs,
noted that we didn't even to take the SMS-1 out of my system to compare With vs. Without SMS-1 Eqing, because it was so clear that my system had never ever sounded this good (and it sounded darn good before).
Well, I decided to take out the SMS-1 Eqing but connecting the sub cable from the CB3's Six Shooter output direct to the front left Aerial sub (chained to the other two subs). WOW! Right away, music I used to love, I no longer wanted to listen to. After a minute, I quickly inserted the SMS-1 back in, and WOW music nirvana.
Here's what Lon had to say about comparing multi-channel SACD music EQed with the SMS-1 vs not using the EQ:
"With the EQ: Overall, more coherent, more of a seamless integration between subs and main speakers, end result being a cleaner, smoother performance, with obviously the improved bottom end improving the overall performance of the mids and highs as well. A substantial sonic improvement."
I was hoping for some improvement with the SMS-1 EQ - but this was a very substantial improvement towards being there live. Quite amazing.
