I have had three Torus units for the last maybe 4yrs. and wouldn't be without them.
First when I had shunyata hydras in my room with approx 6 dedicated lines I had an opportunity to home audition the Torus(15a).
At the time I had 3X7Bssts and 2X4Bssts+subs and components.
Had the amps and most components in the Torus.
Seemed like it was the same as the shunyata( I think it sound beeter or it must be doing something ect).
Wasn't until I tried another Torus with the 15a which was a 20a that all hell broke loose.
it seems that if you add all the amperage of the amps I was looking at around 35a I believe.
Soon as I separated some of the amps onto the 20a Torus it was:eek:WTF.huge stage,very authoritive bottomend ect.
Seems the 15a could not give what the amps wanted just like wall plug,of course it worked but NO DYNAMICS ect.
Someone high up in the industry had told me :you have discovered as I have that having gobs of power in reserve for the amps makes a huge difference.
Reminds me of miking a kick drum using say 100w amp,you gey sound but it sounds like crap,add 500 -1000 it's showtime,huge difference.
Also I two instances where the Torus saved some gear:
#1:Had all my gear plugged into the Torus(s) and my computer into a monster,well we had a storm,the computer was toast,my gear was fine.
#2:last year I had four F-113s,two were connected to a torus and two were not,same thing,had a storm the two that were plugged into the Torus were fine as was everything else.
The two that weren't were done.
LIve and learn as I have everything into three Torus(s),20a(240v)for my components,4Bsst and projector
60a(240V)for my 2X28Bssts+7Bsst for the front
20a(120V)for my 1812 sub with dedicated 20a line
Haven't found anything better yet for protection and that improves the dynamics of the music,I know first hand that shunyata doesn't even come into view and that's with dedicated lines.
I may upgrade a component or amp but the Torus(s) are staying put unless I hear something better and with protection:D.
