Help - Mark Levinson Owners

.
Look at BMI Sharks or Whale Supreme. They are terrific on Levinson and reasonable priced. Buy one used, if you like it, contact Brian Introcaso at BMI ( bmicables@aol.com).
.
In my system and for my ears, I prefer the BMI Sharks over the Shunyata Black Mambo that I had for a while and the Shark was head and shoulders better than the Black Mambo.
.
What ever you do, replace the stock Levinson cords. That is a no brainer. Make sure that you allow for sufficient break in time on a new power cords (100-500 hours +).
.
It is probably worth buying two used power cords and doing some comparative listening before diving into buying a bunch of power cords. I would suggest that you continue to try one used cord at a time and continue till you find your favorite. You can always sell the used power cords for more or less what you pay for them. Just be patient.
.
Please let us know how it all turns out.

Good Luck & Rgds,

I have a NBS Statement power cord that is excellent and both the BMI Shark and Whale Supreme were dramatically better than the NBS. The Shunyata Black Mambo was good but was not even close to being as good as the NBS.
.
I think that BMI Sharks, Whale Supremes and Orca's are by far the best value on the market and outstanding power cords in their own right.

I have to politely disagree with Rex & Larryi. In my system, the sound from my Levinson 23.5 improves greatly and degrades greatly depending on which power cord that is in place.
.
I strongly suggest that you look for a good deal on some used high end power cords, do your own comparative listening, and decide what you like from there. You can easily resell the cords you don't want to keep on Audiogon with little or no loss of money.
.
I went through about 10 different brands and models of power cords in the process when I was looking for an ideal cord and I can assure you I am glad that I did.
.
A good power cord on a pre-amp or CD player is a relatively inexpensive upgrade that can bring a lot of improvement. For me it was a good as a component upgrade.
.
Good Luck and let us know how you make out.

Rex,

I have not had good results with the Shunyata cords (specifically, the Black Mambo). It was certainly better than the stock cords, but killed the detail and left the bass very unfocused, boomy and not at all tuneful.

I have had dramatically good results with the NBS Statement PC and significantly better and terrific results with the top end of the BMI products (Shark and Whale Supreme in particular).
.
My point is that in my system, a great power cord that matches up well with your system, room and sound preference makes a huge difference in what a Levinson Amp is capable of putting out. There was a Jaw dropping difference for not a lot of money.
.
I would suggest that Piperdan experiment with used cords (they sell at great discount to the list prices)and see what works for him. A used BMI Shark can be bought for around $ 300.00 - 350.00 and a Whale Supreme for a bit more. Both of these cords were dramatically better than the Black Mambo (which did help the Levinson Amp, but was no where near as beneficial as the BMI cords).
