Do you plug your power amp or integrated amp directly to the wall outlet or power conditioner?

    Do you turn off your amp with the power switch on your amp or your power conditioner? Thanks.

    Turn off/on the pre-amp, which sends a trigger to the amps to turn off/on.

    I have tried it both ways and see no detriment using my power conditioner so I plug it into the power conditioner.

    YMMV as some conditioners might limit dynamics or change the sound of the amp a bit. You will need to experiement in your own rig to find out for sure.

    I have my int tube amp Unison S6, Squeezebox Touch, and PS Audio DAC plugged into the PS Audio Duet. The reason is the Unison int amp can only be turned off via its power switch and I would like to use the PS Audio Duet switch to turn it off to minimize the wear and tear on the Unison amp. I wonder if there is any ill effect if I use the Duet to turn off my Unison amp or not.

    all amp manuals that I read tell you to plug it directly into the wall, especially those high current amps. I trust the engineers who designed the amp.

    All amp manuals? I have a high current amp and it makes no difference if it's in the wall or power conditioner. That's why I suggested the OP experiment with his gear, in his rig, in his listening environment. Did said engineers expressely say NOT to plug it into a power conditioner because "x" will happen? I'm sure that verbiage appears in some owners manual.

    Here is what my owners manual says. Nowhere does it say NOT to plug it into a power conditioner. The bold part is most likely why I don't hear a difference either way. It's convenient to have it plugged into the power conditioner.

    The amplifier is powered by a toroidal transformer which charges 120,000 uF capacitance. This unregulated supply feeds the output transistors only with a full power ripple of about .3 volt. The power draw of this system is constant regardless of the music playing through the amplifier. As such, it does not depend on a high quality AC outlet or special power cords, since the dynamic performance does not create a variation in AC line draw. If the AC line is running low, the output stage will bias to a higher current level by way of compensation.

    The amplifier is stable into any load impedance or reactance including a direct short. The Aleph 30 is impervious to electrostatic shock at the input and dead shorts at the output. You can safely plug and unplug inputs and outputs while the amplifier is running. (Do not try this with other products). The Aleph 30 is protected from overheating by a 75 degree C. thermostatic switch, and from internal failure by a slow-blow fuse.

    I do not recall reading to plug my amp directly to the wall. Perhaps I need to upgrade to a "High End Amp."

    Have my multi-channel amp, subwoofer and powered speakers all plugged into the conditioner for a total of four amps. I do this mainly because the power conditioner can turn all four amps on or off with the 12V trigger from my pre/pro. Doesn't hurt anything as long as the power conditioner is sufficiently rated for the power draw. This is probably why some high-current amp manufacturers suggest plugging into the wall--a CYA measure in case someone plugs in to an insufficient line conditioner and burns their house down.

    PC's are protected against over current and over voltage draw so the likely hood it would burn your house down is negligable. Also the max rating of the PC is important but unless the rating is really low which indicates a cheaper unit I doubt very much the draw will exceed the capabilities. It is possible certainly, but only in extreme cases and usually if you are running said amps (think Pass mono's, Krell mono's. Levinson mono's, Parasound JC1's, etc) you aren't using a $300-500 PC.

    I'm a "wall" man, myself.

    1. Because I'm too cheap to spend 100s and "100s" on a high end power conditioner
    2. Because many manufacturers tell you to go ahead and plug her in directly.

    Of course, I'm not crazy. So, I'll shut her down when not in use and during electrical storms.
    Massive power conditioners that cost more than some of my amps have always seemed like "overkill" to me. But you have to spend on something, after all! And if you have the "extra" cash, why not? Some of you have "very" deep pockets when all is said and done! And there's nothing wrong with that.

    You don't have to spend big to get big performance/protection. How important is protecting your electronics from the events of which you can not control.

    The power into my home varies significantly throughout the day.

    2 channel:

    Tube amp, tube preamp, CDP, tuner, and external power supply for Wadia iTransport all go into a PS Audio Power Plant Premier. The PS Audio Power Plant Premier goes into a PS Audio Soloist Special Edition. All power cords are PS Audio AC-5's. The Power Plant Premier output reads 121 24/7.

    Home Theater:

    AVR, 3 external amps, blue ray player, Parasound Zbreeze cooling fans and cable box all go into an APC H15. The APC has been going strong for a couple of years now. Actually, thus far the APC has been bullet proof. I really like the APC H15. Especially given it's price point. YMMV.

    Run EVERYTHING through my H15. For its price it works quite nice and has voltage regulation incase I need it (I dont own a home so I have a higher chance of getting crappy wiring and needing voltage regulation).

    It depends on the amp.

    In my master bedroom system, an Adcom GFA-5400 power amp, as well as the entire A/V system, is plugged into a PS Audio Power Plant Premier AC regenerator. The amp sounds much better (deeper, more detailed bass, better imaging) plugged into the regenerator than into the wall.

    In my home theater system, I have three Adcom GFA-5500 power amps plugged into a PS Audio P10 AC regenerator. They all sound better with the regenerator rather than plugged into the wall.

    In my two channel system, my Parasound Halo JC 1 monoblock amps are plugged into a non-current limiting in-wall passive power conditioner (PS Audio Soloist SE) on separate dedicated 20 amp AC circuits. The amps sound better with the Soloist than straight into the wall. I tried running the JC 1's from a PS Audio Power Plant Premier AC regenerator. The PPP shut down. The same thing happened with a PS Audio P5 AC regenerator. A PS Audio P10 was able to run the JC 1's, but with a loss in sound quality. Parasound advised that I would need a commercial grade AC regenerator to meet the current demands of the JC 1.

    Even my little class D amps(wyred 4 sound) sound better straight from the wall. The two Belkin conditioners I tried chocked them pretty bad, and even the two RGPC products I tried negatively effected dynamics.

    Whenever I go out I unplug them.

    FYI, Hypex's new N-Core amps are recommended to be plugged directly into the wall too, conditioners are not recommended.

    Power conditioners stay on 24/7.

    2 channel:

    1. Preamp
    2. Amp
    3. CDP, if use is desired
    4. Tuner, if use is desired

    Shut down is the above reversed.

    Home theater:

    Universal remote and everything powers on via 12 volt triggers.

    For me, it depended on where I lived. Where I used to live power interruptions were practically non-existent, therefore I didn't worry about it much. All power lines were underground and I maybe lost power once a year, there was never a brown out that I was aware of. Now, I live in a much more rural area, power outages are much more frequent, depending on the weather. All power lines are above ground and I'm at the "end of the line" as far as the power lines go. When talking to the neighbors they have also stated they've had stuff fried on brown outs. So..., just for my piece of mind I finally broke down and got the H15.

    I figure it's much cheaper to replace a semi-expensive power conditioner than my whole system...

    (FWIW I didn't notice much of a musical difference with the PC)
