Hi,
First, thanks for your all helps. Just installed 2 dedicated outlets and the sound is much better than before (much more than I expected for the cost of $300). Here are the improvements that I've noted so far.
* Dynamic and Transistion? (Music is faster. It's like I just change new battery)
* More detail, and cymbals is softer
* I can listen in the daytime without having to wait until late night
* The voices is in front a little bit not deep to the back wall like before
And here are the down side
* I hear low base that hang around the room which I didn't hear before (may need tube traps???)
* Turn the volum up to 10db (normally turn the volum -15 before, and now -5db)
* The noise from my speaker (it sounds like a storm buzz..buzz) is stll there when not playing.
I don't have a chance to test which one is better: fuse or breaker. However, I chose fuse because it's easy to pull out for cleaning.
Here is what I did
- Move all the heavy lines to one phase of main breaker
- Use the fist line of the opposite phase
- Run 60A to the sub pannel using 4AWG THHN wire
- Run two separate line (30A each) into the conduit to the outlets using 10AWG THHN wire. Grounded the conduit to the main ground, and use platic box for the outlets.
- Run ground wire from the outlets to the dedicated ground rod using there 8' copper rods deeply into the soil. The copper rods are connected in a triangle within one foot apart.
Last thing, I was lucky to found an electrician who understand the crazy things that I want him to do but within the code (he was the fifth one after I sent home the previous ones because they always aksed me why this.. why that.. I think 12AWG is enough and on..on). I'm so happy with my system now
Happy listening!
DT
