New Dedicated Line - Almost No improvement

If you need to add an additional breaker box make sure your dedicated lines (hopefully you will be adding one for your amp) are wired into the same box… otherwise this may cause a ground loop.  I’ll leave the details of wiring to others. Only, they make a difference… both.

On the spousal acceptance factor. This is definitely something to consider. Personally I would rather put my system in a small room that I control versus a big communal room. Treatments and careful choices can make a system sound amazing in a large closet… but a really expensive system can end up sounding not so good when placement is compromised and treatments (especially something like lots of windows) cannot be installed. 
 

Did you really think a dedicated line would make an improvement ?

Properly designed electronics INTERNALLY has all the necessary filters & mechanisms necessary to generate a good enough & acceptable DC.  Nothing external is needed.

The only requirement from the mains is that it is reasonably sinusoidal so the transformers work properly, and the voltage stays within a reasonable range.

Unless you are driving synchronous motors, even the frequency deviation does not matter so much, as long as the frequency does not drop below a number which causes the transformers to heat up.  Besides, not even the WORST mains supply in any country does not have fluctuating frequency to such a degree.

Inverter systems sound as different as anything.....here is one that will blow your mind.......incredible sound....everything you do makes a difference...even how an inverter is mounted.

On come on @westcoastaudiophile , you don’t need and unlimited budget. The average audiophile product includes more than enough budget to implement an adequate power supply. The issues are often not the power supply at all or just require good design practices, not even a lot of cost.

How are you finding those Ampere Time batteries @ricevs ??  Saw them on Amazon. They seemed at the time a bit lower cost than others but not much difference between the brands. I have built up my own 24V batteries for my big boat using 200aH LiFeP04 3.2V cells, and an off the shelf BMS. Too many BMS failures. I wanted something that in a pinch I could bypass in and keep operating.  Been looking for some 100Ah or 200Ah for the fishing boat.

RE: outlet burn-in. Interesting and I had no idea. As a newbie I think burn in is the most annoying thing about this hobby (wife issues aside). I'll just leave them in because ......although I have about 180 hours on my Sapphire M3s and about 90 hours on the tweeters (had to replace those after too much volume) I'm reading again and again on Audio Circle that they really need 500 hours so I've got a ways to go before those are burned in anyway. That said, if I wanted to speed up the process I could remove one at a time and run my PC through it that I'm on all day at work.

RE: Spouse and dedicated room. We have a 4 BR home, mbr, office, wife's office and yoga room and lastly a spare BR. So they are all taken. My plan is that she usually stops watching tv around 9:30 PM and then spends 2 hours doing chick stuff. If I'm not buried at work I will be able to listen from 9:30-11:30 once (!!!) I sound proof the MBR door some wich of course leads out to the LR/stereo room. I figure once I sound proof the door (as much as possible) i can at least listen at 70 db which is fine. Then when she leaves for doctor or hair or yoga the volume will immediately go up to 85-90 db which is where i usually like it.

RE: the topic of this thread :) , so many opinions (which of course is fine and the reason I created it) that I'll have to spend some more time sorting through them. I do want to look at a few things mentioned and will be discussing with my electrician and will also read ditusa'a link. I been slammed at work today (with a ways to go) so I haven't had a chance to look in the breaker box again but will do so. 

RE: impact of SQ - I was just reading my EMI reading for the dedicated outlet vs. the regular outlets and not seeing much of a change. May or may not affect SQ. In an earlier post someone made a good point about this when listening to quieter passages - which I will do once I mount my cart and will put on the Wall or DSOTM or Abaraxis (sp) - there is a long list to choose from.

Thanks again all. I appreciate your time and expertise. As mentioned I will go through all of these a few times – especially this weekend when I have more time for it to sink in and look at the panel/breaker box. Will also discuss w/ my electrician.
