Power Conditioners - Best Set-Up

Lrmljaf, As Psychicanimal has stated, you've got some homework to do. The statement you made regarding amplifiers and power conditioners is partially accurate. In many cases, passive power conditioning will act as a "choke" to your amplifier. In other words, the amp will demand a higher level of current draw than the power conditioner is capable of providing it.

If the dedicated line you are presently using is 15 amps, a well built 200 watt per channel amp will suck it dry. Many passive power conditioning units are built for a maximum 15 amp current draw. If your amp is doubling it's output power based on load, ie: 200/400/800 watts per channel, you've just drained your wall receptacle. That's just the amp alone, now what about all the other components you have plugged into it?

If you have a dedicated 20 amp receptacle, that will allow you a little more wiggle room. Active power conditioning units (PS Audio, Accuphase, Exactpower, etc.) will help to keep your AC more stable during high current draw scenarios, but still will not always provide the high current needed.

Now I know I'm gonna get hammered for this but, here goes.
I personally have found that ANY form of passive power conditioning restricts current draw to the amp. And I use a small 100 wpc integrated. But, even that small integrated will draw as much as 900 watts, during let's say, the Telarc version of the 1812 overture. (you probably know about the cannons?)

Imagine what would happen if I use using A 200 watt amp?

In terms of everything but the amp, I use a passive conditioner plugged into an active conditioner. The amp is plugged directly into the active conditioner, everyting else is plugged into the passive. That provides filtration, including digital, isolation between components, and does not choke the amp.

And, I'm also assuming that your isolated outlet is also using an isolated ground? Is that correct?

Buscis2 - That's a pretty detailed answer, and I appreciate the time you spent on it.

Let me give you some more information. I actually have two 20 amp dedicated lines with seperate isolated grounds with direct feeds to the main electrical box. My amp is rated at 90 watts @ 8 ohms and it's a tube unit.

The amp gets one of the dedicated lines along with a tuner and VCR. While the other dedicated line gets the tube pre-amp, CD Player, and TV.

Does this info help?

Thanks again for your time.

I would suggest using Bybee Technologie Signature or All Pro power conditioner. I have used many types of PCs (PS Audio 300, Tice, API, Hydra and Sound Application and now ending up with the Classic Bybee Tech Signature. My system has a lot of improvement in detail, musical and dynamic. Using PCs is the best for front end like CDP, Analog like turntable,DAC&Transport, Preamp...

Lrm1jmf, You have obviously provided more than enough dedicated power for your system. If you are running 90wpc you should have more than enough power available at the wall. Now the question is, what to do with the power in terms of processing.

I very rarely get involved in threads that involve mentioning brand names. I find it is about the easiest way to start the packs of wolves to come "out searchin for ya". This site could be a tough environment. But, OH WELL!

I use an Exactpower EP-15 active power conditioner. The EP partially regenerates the AC waveform. The PS Audio units completely regenerates the AC waveform. The PS Audio, because of this, is not very efficient. The reason being, the PS uses almost as much power as it regenerates. So, if you're generating 600 watts, you're using 600 watts. The EP uses 35 watts. On the 15 amp EP, 1600 watts in, approx. 1550 out. That's pretty efficient.

The EP regenerates an AC waveform that is pretty much devoid of any AC distortion. If you were to look at the AC waveform coming from your wall, you would more than likely find that the waveform is corrupted on the tops and bottoms of the waveform peaks. That's AC distortion. Now think of what happens when you send it to your AMPLIFIER. The EP is about the only unit (other than the Accuphase @ $8000) that does this. Although Paul McGowan over at PS Audio will soon be releasing a unit that is somewhat similar to the EP in terms of design. But, I didn't say that.

Unfortunately, neither of these units provide filtering or isolation for the other components. That is why I use a passive conditioner containing filtration for the rest of my components. I think you may find the filtering portion of the equation to be as important as the regeneration portion. Filtering the digital portion of your system is probably the most important. Digital nasties backfeed into you AC power and can create a general "haze" in the overall sound of your system. Electric motors, such as in your VCR, or if you were using a turntable also send AC grunge back into you AC.

There is a rule of thumb that you can follow in regards to AC power processing and conditioning; Remove the distortion, generate a clean AC signal, and don't let the distortion get back in. (Regenerate, fiter and isolate). If you follow that path, you will be guaranteed clean power and sweet sound.

Do a little reading on the Exactpower unit, which is now available in a 20 amp version, and also do some reading on the PS Audio. After that you will need to figure out what you will want to use for a filtering device (passive).

It's taken me over 3 months of auditioning to get where I'm going with this whole AC thing. It pisses me off that I have to correct the garbage that my utility company is providing me. But, that and 10 cents will get me a cup of coffee. Oh Well.

Nguyenchiro, you forgot one conditioner, a BPT balanced power conditioner w/ Bybee`s. If you havn`t tried one, you should as they`re a very musical conditioner. The Plitron NoLo torridal transformer is well regarded for their musicality and the addition of 2 Bybee`s further it`s depth perception. Regards, Robin
