RECOMMEDATIONS FOR AC RECEPTACLE


A friend of mine convinced me to purchase two PS audio Power Ports. Received them and installed them and almost immediately I notice my HDTV picture had greater clarity and it cleaned up the video noise. The Picture is awesome and the graphics didn't have those little jagged edges.
In the meantime, my music jumped out at me, with greater transparent detail, depth, and tighter bass. But I also noticed that the highs were a tad bit harsh especially on piano.
Just finished running a dedicated line with two circuits with an isolated ground. I understand that this will make my system sound and look even better.I would like to hear suggestions for AC outlets that will be an improvement over the PS audio Power Port, i.e. getting rid of the harshness. I know this will be very subjective, but I would like to hear what you guys have to say. I have gotten some great advice in times past.

BTW my equipment: Meridian 568MM.2, Meridian 518, B&W 801's series 80 with bybees, B&w cc80's sides and rears, B&w HTM2 Center channel, Velodyne Sub 12", Denon 2910 DVD, Earthquake Cinenova 5 channel with dakiom stabilizers, B&k 2 channel amp, Mitsubishi Diamond series 73" 1080p HDTV, slim Device Squeezebox, Monster Power HTS 5000.
Everything is looking good and sounding good but as you know good is the adversary of better. Waiting to hear

I do agree, "good is the enemy of the best"... but I'll take a different tact.

I don't think it's the outlet adding to the problem. it maybe is helping to show it though.

I've four dedicated lines. Worried about outlets a goodly bit. Leaned on my experience as an electrician and decided this... use those outlets which will provide insertion of a device without arcing, and have the greatest surface area and grip. I went with simple hospital grade 20a duplex outlets.

given the level of gear you posted here, I'd think well about replacing the Monster regulator as they tend to induce more of a hardend upper end. Perhaps thinking about a passive line filter coming off the Monster, or in place of it would provide better results. I use only the aforementioned hosp grade 20a outlets and PS Audio line filters. Two Duets for the gear, and a UPC 200 for all the wall warts and PC gear. I could not be happier... and maybe ignorance is bliss. Don't know, but that path does work quite well.

If it were otherwise, and ONLY attention needs be given to the outlet itself, Why then are the proponents of these higher priced gizmos using apparatus after the outlet to further condition system conponents?

Spend money where it needs be spent, I say. tight gripping well made, durable outlets, and condition thereafter using the money you didn't spend on outlets.

As I mentioned previously, the issue maybe elsewhere... dedicated lines aren't the end all be all for supplying components good power. if the dedicated lines were installed using the same bus as that supplying household appliances, fans, hot water heaters, fridges, etc, or lighting with poorly designed dampers, you've not helped yourself a lot. Some good bit, but not terribly.

The thing about dedicated lines is this, ultimatedly they share whatever issues are pre-exsisting in the homes power feed. The same neutral/return, and the same supply bus. Dedicated is segregated or separated entirely, just lessend of the direct impact or influence of other problems. A separately installed iso transformer is needed to better remove any issues from that of the feed to those D lines.

Quick note... you said you were using a secondary isolated ground. Although a good idea usually, Depending upon the application/implementation of the iso ground, some difference of poetential can exist... causing a ground loop. An easy fix for that is an inductor. Simply looping some 10 or 12 AWG solid wire wound round and roung and then taped up and shoved into the wall, can eliminate that issue sufficiently to make it unoticeable.

Remenber unless the D lines use a t-former, somwhere along the line, somewhere in the home, both the neutral and the other ground come back into the ckt.... just the effect is lessend or takes longer to be realized.

When I installed my hosp outlets I did not add the ground/common line of the D ckts to every outlet. Just one. Violin! No hum, buzz, sibalence, top end harshness. Dead quiet, and I use tube preamp and mono blocks.

I found that elsewhere in my home, other things were either contributing to, or directly affecting that top end, or upper midrange on up... ground loops, primarily, but appliances too. I put chaeater plugs on the washing mach. diswasher, and fridge. Five minutes and 2 bucks later thijngs were better.

Also, Computers and their accesories leak DC back onto the power line. Hence the UPC 200 AND SOME EXTENSION CORDS. Even my cable system and/or sattelite added to the mix negatively. I used a coax transformer from Dayton on the cable feed directly attached to the converter box, which in turn is connected to my system.

before spending tons on a new set of whozits high end outlets, or making major moves in the system... Fire up the system and listen a bit, then turn off the rest of the breakers in the home not associated with the system, and listen. how's the sound? then one by one flip on a breaker, listen again.. this can be done pretty rapidly, with just a few minutes between each energizing... and just keep listening. Another body to just flip the breakers on whill facilitate things. I think you'll find the issue that way... if nothing changes as the result of that exercise, Try just unplugging the coax going to the cable/sat box, or ant to the TV.

Taking a few minutes to do the above is quite telling and my most sincere recommendation. Addressing a problem is best done if you know first hand where or what the problem is at the on set. therre's no guess work then.

THEN go add well built outlets and conditoning thereafter IF desired or even necessary, and I do feel they are.

Before I spent hundreds of dollars on something that I don't know about, I'd spend a few minutes determining what I do know.

Good luck.

Blindjim, I appreciate your detailed response to my questions. What a novel thought: Define the problem before trying to bring solutions to it.
First of all I will perform the breaker test and the unplugging of the connections to the cable...These are easy and very economical.

I was already looking into another power conditioner or I may take your advice and add a passive line filter.
The Bybee purifiers and the dakiom stabilizers are all tweaks I purchase prior to the Meridian 568MM.

My B&W 801's are about 20 years old and when I first got them they were a little muddy sounding on the bass. Adding the bybee purifiers, unplugging the automatic overload protection circuit and adding speaker stands tightened the bass. Found out from reading forums like this, that all they needed was clean, high current power. The Earthquake Cinenova 5ch 300wpc continuous made the bass even tighter and deeper. AS a matter of fact, a friend of mine has the B&W Nautilus 802's and he always declares that my mids and highs are cleaner than his. His opinion which I concur with.

I am going to trouble shoot the harshness by going back and removing the dakiom purifiers. May also remove the bybees to see if they are contributing to my problem, I doubt it, but will give it a try.

Blindjim besides the obvious what are the advantages of a 20 amp outlet compared to a 15amp?
Thankyou so much!
I've used the Power Ports, various Furutechs, various Wattgates and all the Oyaides. The Oyaide R1s outperform all the others in my system, greater transparency and detail without any edge or stridency, there is simply no downside in my system. Initially I was skeptical that one ac receptacle could be that much better than others, however, the R1 is a big step up! Mine were also cyro treated by Alan at Audio Excellence, good guy.
I got several cryo'd Ac receptacles from Cryoparts here on Audiogon. They are Hubble and P&S. The top end through my maggies now have less grain. It was a small but noticable improvement for around $15. I now plug my powervar into it. Highly recommended. Next, I will try changing all the AC recepticles in the powervar.
