You never forget... I still do all my own work. Go for it, Richard!

The advice to run two dedicated circuits at the same time rather than a single dedicated circuit is good advice. The material cost doubles but the additional labor is minimal. Having more available power than you may need at this moment is always advantages.


Thanks

Right now everything is running on 1 15 amp circuit, so I will install 2 20 amp. 1 for the two 2301s and 1 for the rel g2s Because of the location of the the other gear, it would require me to run conduit on the outside of the house and puncture the stone to exit and reenter. So for now the C1100, D1100, N10, Phono stage, R2R, TT, and P10 will stay on the 15 amp.

My hope is after doing this work, I will here some kind of improvements

Go for 2 like everyone suggests. I have installed 20 amp dedicated lines on 2 separate occasions. I definitely noticed a smoother presentation.

Richard.......Is the 15 amp circuit for the P10, preamp, and source components a dedicated circuit?

Default Dedicated Circuit, Circuits?

Richard,

While I have three dedicated 20 amp lines in my room, for added safety mostly, I am running my entire system from the P10 and one 20 amp line.

I haven’t noticed any reduction of SQ and I like the one extra layer of power stability to protect all my equipment from voltage spikes etc.

At full blow, my P10 gets pretty warm and shows 65 - 70% load. Right now listening at slightly above average levels, the P10 reads 6.76 Amps, 651 Watts at 67% load.

I should add the figures above are with the waveform set to SINE, interestingly enough, if I change it to MULTI, the figures drop to 537 watts, 5.22 amps and 52% load.

Can’t hear any difference.

What do you use with your system?

P10 on the front end, nothing on the back. That’s next up. Power cords and ?

I Pulled 2, 20 amp dedicated circuits, and made a provision for a third ( 12/2, wire is in the attic above the source electronics but not pulled thru the wall yet.)

The 2 that are finished are now being used as follows. the 2301's are now connected to 1 and the 2 REL g-2's are connected to the other.

I did not complete the third for two reasons. first I will have to remove everything from the SRA rack and move rack, this was more work than I planned for.

Second the 15 amp circuit that is in the room only services that room, only three things are attached. The P10 which then all front end electronics are attached to , Klaudio's KD-CLN-LP200, which I only use when audio gear is off. and the light which I usually have off when listening. The blue light from the meters light the room enough for me.

So far with only about 20 minuets of listening I can notice a improvement in a blacker background.

Now I'm considering looking at the Nordost power cords and power products for the 2301's. and some upgraded Neutrik Speakon cables for the REL G-2's

Does it make sense to upgrade the power cords on the G-2s ?

Thanks in advance
