Thanx. Maybe the partsexpress isolator is the thing to get. I will try looking into your circuit load advice during the week.

Thanx for the advice. I clearly understand your point and could potentially use a LS as a center now, as neither is currently used. I actually have the Heresys on top of the LSs (due to space issues) and use the Heresys as my rears.
My couch is low and I spend a lot of time on the floor too.
My 20 yr old 26" Sony could not even be killed by Katrina. With a LaScala center, my TV would be too high on top of it
As is, the Academy's weight warps the TV top a bit. It was the best compromise I could figure out 14 yrs ago, when the LSs were my BR speakers in Phoenix.
Also, horn loaded speakers are very directional and the mid range and tweeter need to be kept near ear level. A sideways LaScala would look a bit goofy. My TV would still be higher than on it's existing stand and the LS is not shielded.
If you use a Belle or a LS center, do you put your CRT TV or Flat screen TV on top of it (again, too high for me)?

oh, no difference which outlet (of the 2 reasonably available) I plugged the subs into - 1 was for the main stereo equipment. I was also afraid of overloading a circuit with 4 amps (about 3000w ttl), TV, preamp/processor, vcr, dvd, turntable, 2 tape decks, clock, etc....

Yes, the hum goes away when the cable TV line is disconnected, but then again, the TV goes away too
Wierd how it did not occur with the prior amps which only had 2 prong plugs.
I think I got about a 2/3 improvement by running a 2 foot long speaker wire from the cable ?shield to the strip outlet ground. If that is unsafe, I will undo it (still reading the pdf). The hum went away for seconds at a time, but always recurred.
I also tried to determine the Ohm differential, but analog and digital multimeters gave very different results. 1-1.2 Ohns analog, up to 8 digital. (Cable TV wire to strip outlet ground). Is there some kind of Ohm balancer that Radio Shack would have?
In the French Quarter of New Orleans, no telling where my cable box is. There is "a" cable box, rather mangled, about 100 feet from my slave quarter apt at the front of the main house. It is outside, so no ready way for me to ground that cable box to my inside ground. I have no way of knowing if the cable box and the house are grounded to the same spot(s). My wires could also be from a box on a neighboring property. That is not uncommon here.
I do not wish to make any safety hazards.

Hope I posted in the right place.
As part of redoing my place in New Orleans, I am thinking of doing a 3.1 or 5.1 in the bedroom.
My main room has K horns, LaScalas, Heresys (1st version), paired subs, and Academy center. If I move LSs (which I think are too big for the bedroom) or the Heresys to the bedroom, what center channel would be best? I think another single Heresy or Academy might work. I have seen postings about the RC-7s and have heard the 62s locally.The 64s were a bit pricey. If found used and in good shape, the first 2 choices should be in the $150-350 range. The others new, close or a bit more. I would likely get a small commercial sub too. If I could fit rear speakers.....no clue yet. My BR is about 15 x 17 but entry doors, closet locs, layout make the space a real challenge as it not the typical box shape.
Thanx in advance for your thoughts.

My room is about 17 by 40. It includes den, study, dining area, and kitchen. I only use the front third for music and HT. Because my couch is low and I have a 26" 20 yr old Sony, that even Katrina could not kill, I use an Academy center. I have K horns up front, paired subs, and can use LaScala's or Heresy's (which currently are right on top of the LS) in the rear. In my room and for my ears, unless you like true 5 ch audio, the LSs in the rear are overkill, so I actually only hook up the Heresy's in the rear. (But the LSs won't fit in the bedroom and I won't sell them). I have never put a LS between the K horns, because if I put my TV on top of it, the TV would be too high for me. I think the sound would likely be grand though. Keep the height of your TV in mind. I also live on the floor for hours at a time. So again, a low TV makes more sense for me. If you have small kids, a high TV may be safe, but they may not be able to see it from the floor.
I agree that for HT the center is very important. I use an Academy. It sounds fine and fits on top of my TV, while only mildly crushing and warping the TV top. Nothing heavier would work for me. Nothing bigger is adequately shielded-although I am told you could use roofers steel from Home Depot to shield the TV if you used Heresys under the TV as a center. That would still raise my TV.
Remeber, your folded horn speakers are directional. Unless you have a projection TV with a semitransparent screen for the horn speakers to shoot thru or unless your TV height is high a single LS or Belle could cause some issues. You want the horns to fire to your ear level. Could the other posters reply to this (unless they just have high TVs).
Just my 2 cents.

Hello
My post Katrina set up includes:
Klipschorns, Academy center, LaScalas and Heresys rear
Paired subwoofers from Madison Amps (218s)
Mc240 Tube amp for Khorns
Outlaw 750 for center and rear
Dayton Audio 1000w amps for subs.
My preamp/processor ia an Outlaw 990. It offers about 12different modes for phono. These include basic stereo (I think all other spkrs are turned off, limits bass to Khorns), bypass, 5ch, some Dolby PL IIs, Neo 6? etc.
Most of my new "old" records are from the 50s-80s, Jazz-Rock. Some were recorded in mono. I think some of the records are awesome. I can't explain it, but I think they sound better than some CDs. Most of the sound modes offered on the 990 sound quite nice, but they are very different. In order to achieve the closest approximation to being in the studio when the tracks were laid down (which I think is our goal), is simple good old fashioned stero the best mode? I will assume the answer will also be true for my cassette tapes, mostly from the 80s-if not, le me know.
Thanx for any advice.

I have a technical Q. Speakers incl Klipschorns, LaScala's, Heresys, and Academy center.
Since buying dedicated sub amps (2) I have GL Hum probs. Each sub amp has a 3 pronged plug. I actually don't have a 3 prong to 2 prong converter or cheater lying around and I do not want to mess with the new 1000w sub amps if possible. The prior Adcom stereo amps used in bridge mode were located in a different - but poor - position and the sub cable path and speaker wire path are also changed. On the prior non ideal placement and amp set up there was no GL hum - but, the prior amps only had 2 prong electric plugs. My Mac tube amp also is 2 pronged and my Outlaw 750 SS amp, well I can't see back that far...
I found that by grounding the cable TV outer plug to a ground outlet plug of a 3 plug outlet strip hum is much reduced though still notable and bothersome. Changing outlets for the new amps and messing with the turntable ground wire does not seem to change anything. I do not know where the cable TV ground is located. The distance from cable TV splitter at home entry to sub amps is too far for the "lamp cord" speaker wire I have left now to attempt to ground to sub amp chassis. I will likely try that next. Each sub amp has a 3 prong plug.
Other solutions I have found include getting 2 different 300/75 and 75/300 ohm tv converters and connecting them. May mess up TV signal, but a $5-10 solution. Also, getting an isolation transformer. Not cheap at $40-60 from Jensen Transformers. Parts Express 180-075 is about $11.00.
As stated, the 3->2 prong cheater (which I really prefer not to do) and directly grounding the cable outer shell to my sub amps are also possible (with more speaker wire).
Anyone have any other suggestions?
