Power cords to the same outlet

A 15 amp circuit at a nominal 115 volts has 1725 watts of available power. Compare that against the maximum operating power required by the 2 amplifiers. If your operating power requirements of all connected equipment is nearing 1500 watts you want to seriously consider adding another circuit to prevent voltage drop problems.

With monoblocks there are some who favor putting them on two circuits. Each one on opposite sides of the mains breaker. Supposedly this setup aids in canceling common noise. There are ways to simulate this setup if you want to see whether it's benefical in your situation. My method requires you know how to use a voltmeter however.

Radioman; It looks to me that (based on Alex's 1725 watts) you, at the very least, have adequate watt capacity with the outlets you have safety wise. I've done some research on Proac speakers, and the 2.5/3.8s I believe have easy to drive impedence (about 8 Ohm)-- nice speakers BTW. Also, the Rogue monos should not be a difficult load electrically, ie as impedence drops, tube amps do not increase their power demands like a good SS amp does. As Alex notes, I've also read that it's desirable sonically to have the monos on different circuits, but probably all the existing outlets in your room are on the same circuit anyway. BTW, last summer I had an electrician put in 4 Hubbell duplex dedicated outlets and dedicated ground, and it dropped the music's noise floor dramatically, but then required good quality power cords to get rid of brightness (from the stock cheap power cords). Total cost was about $850.-- mostly labor. Good Luck. Craig

The Rogue will sound better with new AC cords.The stock ones like all stock ac cords are average.

You have to be careful when it comes to breaking your system up onto different outlets. Unless all of the outlets are on the same circuit breaker or fuse, you can easily run into ground loops, higher noise floors, etc... I found this out the hard way when i went to some mono-blocks in my computer room system last year. Due to their location, i had to use two different outlets. While i could never put my finger on it, the system just never sounded right after that. As it turns out, I had a low level buzz coming throughout the whole system that was hardly noticeable due to all of the ambient noise in the room ( air cleaner, ionizer, etc..) Once i got the plug situation straightened out, it sounded far superior and i had to wonder how i had been listening to it like that for so long. Besides having to worry about ground loops, make sure that the outlets are wired in phase with each other. I've had outlets that were wired backwards from one another and that made a big difference, especially on the phono stage. TONS more noise due to the high gain. Sean

HI Sean. Can you help with what instrament/and the "how to" to check phase? I am doing maybe the unthinkable. I take a 3 wire 220 air conditioner circuit( 2 20 amp breakers joined in the box) black and white are both hot/the bare copper,being the neutral. A black and the bare copper being one outlet. The white and the same copper being another outlet.I have been doing this for 7/8years.-----But,how to tell;are they phase?
