Best power cable for levinon no 336?

I use Synergistic Research cables with my Levinson with excellent results. There is a way to change the powercord on your 336. You will have to cut the powercord off at about 8 inches. Then attach a male IEC connection. Nw you can plug a power cord in! This works very well, I owned a 336 at one time and modified it in this way. You could also remove the cover, find the taps where the current power cable is attached, cut off the end of the power cable you want to use and wire it direct. However I believe the first method would be the best.
Hope this helps!

Those are good points, especially about the resale. However all their new amps except the 33h now have detachable powercords. I own 436 amps which are monoblocks in the same powerrange as the 336, and the type of powercords used does make a difference. Some people might be relieved that they can update the powercord if you make the mod.

One could just open the 336, take loose the powercord by unscrewing it from the taps, buy about a foot of 10 guage stranded, flexible wire at Home Depot (I've used this for power cords and it sounds very good), connect it inside the amp, (be sure to note which taps the orginal wires (hot, nuetral, and ground, and draw a picture where they are all connected) , add the male IEC to the other end, and then you can experiment with other powercords to you ears' content. If you decide to sell the amp you can always reattach everything as before and your 336 would be "stock".
I would only attempt this if you have basic wiring skills or a friend familiar with electrical connections. As I recall once you have the cover off the 336, the powercord connections are really straight forward requiring average technical skill, but be sure to sketch the wiring arrangement so there is no doubt where to reattach everything when you get done.
Enjoy,

Not to cause a commotion, and I do not claim to know exactly "why" but that last 3 foot of cable does indeed make a difference to your components in systems like you're building. I have heard the differences that power cables can make in a variety of systems at my home and a friends. I have heard cable changes degrade and enhance the sound. Is there some "snake oil" out there in the hobby, "yes" but in my experience many of the tweaks make more than subtle differeneces in your system.
Running a dedicated electrical line to your amp of at least 20 amps will make more of a differnce than the power cord. While your at it, run another line to for your digital gear and one to your preamp if possible. I've found that these tweaks were more profound than any other tweak I've made.

I have a friend who was a linesman for AmerenUE. He gives me advice and help at times. While doing this work is not difficult, it was easier for me because I had an unfinished basement to work with. I'm not sure where your stereo is located in relation to your electrical box, but the new lines have to end up there. Getting the lines to your system in a finished house is problematic but not impossible. You also must have room in your electrical service box to add the lines. If you don't know someone that can help, then I'd consult an electrician for your safety and asthetics.

It should be an easy job for your electrician to handle. You'll really be surprised how good it will sound. Be sure to use at 10 guage wire. You'll want 30 amp circuit for your amp.
