Thread: Shunyata advice needed

My set up consist of 300B SET amplifiers driving very sensitive 3-way horn loudspeakers and about most little things I tried in making small changes were audible, so along the years I have to search harder for the next improvement step.
Powerline is directly going to the system and soon, the current powerline will even be replaced by a larger diameter core cable, breaker audiophile etc.
Power conditioning, ISOTek, but trying that on the two 300B amps really killed the dynamics so it's straight into the wall socket for now.

Looking ahead, shunyata, very attractive approach of not having components put in series and trying to "block" noise. On one side there are units as the Typhon, could be paralleled to the mains, NR cables cancel noise by just plugging in one-sided and even more when fully connected and then there are the power units as Everest, Denali etc.

In my situation I would be tempted to go for 2 NR cables and connecting these to my dedicated powerline. Would this be the wrong approach or thinkable it will do the same as having a powerconditioner for these two power amps?

Hello, Make sure you listen very carefully if you audition the NR cords in your system--my case in point --

I purchased on the readings of the prime reviews here and elsewhere, I decided my first sojourn into the Shunyata world would be a NR-V12 and NR-V10 ( both new)Power Cable for my

MacTone 300B PowerAmp and Naim CDS555 Player.

Upon first insertion and playing my test tracks --?? I found the soundstage had shrunk and there was slight dullness to the playback--hmm!

I found this most puzzling but thought to allow some days to burn in and see if my previous sonics I know well would return and even improve to my ears.

I allowed 10 days of solid burn in -as I'm retired I was able to play many hours both day and into the night.

Sadly--into the end of the second week there was no difference from the first day so I reluctantly sold the cables--at least they are very saleable so no problems there.

While my first venture into the Shunyata realm did not eventuate to my liking( I replaced my old PC cables back and the magic of the CD555 returned thank heavens!--)

Perusing the reasons maybe the NR circuitry(?) did not go hand in hand with the Naim PSU--I'll never find an answer I guess.

In closing allow me to state the the finish and workmanship of the Shunyata brand is beyond reproach and I urge intended users to try and audition the Products--I'm sure there is sonic nirvana

somewhere in the placement of the Brand in your setup.

Good listening,

Bruce

Hi Bruce, thanks for sharing your experience! Reminds me a bit of having the ISOtek filtering connected to the 300B's.

You mention "NR circuitry" but I would not be sure if it is really an internal circuit that kills the noise here. Then again, if "IT" is killing noise it could be killing some of the better pieces in sound perhaps?

Possibly--I was told there is some "items" in the Plugs themselves-so the NR cabling is total package--no mistake they are whisper quiet and I'm sure will please 99%

of owners --Just didn't do it for me

I sorta felt the baby went out with the bathwater.

Beautifully finished and packaged though- 100% for presentation.

Good luck,

Bruce

My understanding from Shunyata is basic recommendation is if your amps are on a dedicated circuit to use the NR power cables directly into the wall. The NR cables have some noise filtering capability while not restricting current delivery. Shunyata measures DTDC and you should see higher DTDC as you go up their line. When you reach Omega level, they include their QR/BB tech in the cable which is supposed to provide an additional reserve of power like a capacitor but be very DTDC friendly.

If the amps share a circuit and you have Everest/Denali, then plug them into those.

Obviously, these are general guidelines and YMMV. Also, what I don’t know is how non Shunyata power equipment should or should not interact. Might be a very individual setup thing. But your initial scenario of plugging amps directly into wall with NR cables seems viable.

Btw, this is my own read on Shunyata NR power cables. It does seem the NR cables all share similar noise reduction technology as they all show >12db noise reduction. Going up the line seems to be more about better materials/construction and a bunch of stuff around delivering better DTDC.
