High Fidelity Cables MC-0.5 Effect


I'm looking for some advice please.
Has anyone used/is using a High Fidelity Cables MC-0.5 Power Conditioner?
What are your observations?
I'm looking at possibly getting one.

Have a number of extras already:
- Akiko Triple AC Power Enhancer
- Akiko Audio Fuse Box Tuning Chip
- iFi AC iPurifier
- Russ Andrews 'The Silencer'
- Mad Scientist Nitro power cables
- Signal Ground Solutions Grounding Box
- Bybee iQSE

I'm not looking for comments from those who have not heard this in a system.

Mad Scientist Nitro Nano is much better than Nitro
Have contacted Bob.
Will replace the Nitro with the Nitro Nano, after I pay for some Black Ravioli pads.
I auditioned the MC-0.5's. I used two modules in my system and the effect they had on my music was astounding. They're not power conditioners, although they do lower the noise floor, but they create a holographic image. It's so hard to explain in words, but the music image is very clean with instruments sounding more realistic in terms of tonal quality, attack and decay, and a more defined sense of the recording space. It's more than what we call soundstage, it takes you closer to being there.

It was very addictive. Unfortunately for me, they ultimately didn't work out in my listening room. My system is neutral with smooth extended highs. Over time, the modules created such top-end extension that my digital setup became very fatiguing to me.
After removing them, I missed the holographic sound they had created, but I preferred my analogue-like digital system.

I use a HF CT-2 digital cable with streaming and CD playback to an Audio Note DAC.
I suppose I could have made some tweaks such as tube rolling to retune my system. 

I still will recommend them, YMMV.



I have one installed in my system and find it to be the perhaps the best value system enhancement I've ever used. Fortunately, I've experienced all the positive results and none of the negatives lowrider57 noted. The MC-0.5 removes harsh and artificial artifacts present in music reproduction (that you weren't even aware were there until removed) and takes your system another step closer to sounding like real music. Like lowrider57, I would characterize my system as neutral with smooth extended highs. Evidently, the usual caveat of "YMMV" is at play. 
@photon46 , the sense of realism really is remarkable. Maybe your next upgrade should be a second MC-0.5. 

I probably could have made the modules fit my system, but it would have involved tube and cable rolling.
   I experimented using only one module, but the pair was twice as good. 


The MC .O5s where a game changer for me. Easy to use, short break in. Had good results right away ten hours or less. Best results was at the wall for me. If you can swing 3 on 1 power line, think you will be impressed. I did get good results starting with 2. The more i add it just got better.

These all sound promising. Thanks.
And I'm keen to try an MC 0.5
Like the idea of lower noise floor, more realistic instruments.
And more analogue.

With my above tweaks (Akiko etc), the sound has improved greatly over the past 12 months. Improved soundstage, quieter, better instrument separation, richness of the sound, and less digital.

I'm trying to eek out the best I can, from what I have.
Not a 'high end' system, but does have a sound I like.

I only have two power points, in a small cupboard.
One for the amp using the Mad Scientist Nitro.
The other has a second Mad Scientist Nitro hard wired to an Eichmann power strip. The MC 0.5 would plug into the Eichmann.

I'm guessing would still have a positive effect.

I have a simple system all so. A dedicated line for my amp and one line that feeds my front end. I started with one MC O.5 on my amp line at the wall. This was a noticeable improvement. I add one to the front end side and the improvement was all so noticeable. As i add more to each line the front end side improved even better. The amp side got better but not as a big jump compared to the front end side. The more MC O.5 i add the sound just got better. Just remember to give them some time at where you put them. If you change them around the settle in times starts over.
Right now on A'gon they are 35% off for new and 40% off for B-stock. I ordered one and will report back on what I hear. 
Don’t bother looking anymore: https://www.youtube.com/watch?v=DgS4DD0CgHs&frags=pl%2Cwn

I should have said nothing as I was planning on getting another if it proved to be of benefit.
Oh well. 😉

So many positive experiences, I'd like to give the 0.5's another try. My amp was having problems at the time; hum and power tubes red plated. Maybe this affected the overall performance. Amp is in the shop now, bad resistors found  with low voltage from transformer.

Anybody know if noise from the amp (hum and buzzing)  would affect the performance of the 0.5's while playing music? The highs were not smooth with the modules installed and presented overall harshness, even though there were benefits to imaging.
   I purchased the amp (used)  about the same time as the modules.

When I returned the modules to the dealer, he was very surprised they didn't improve the sound of my system.

Just bought an MC-0.5 B stock at 40% discount, reposted ad.
@jerrybj,
Just listened for about 4 hours with the MC-0.5 in place and it’s staying there. I just might get another. No more need for the Blue Circle Thingee anymore. Loving the results would be an understatement. Sliced bread is now relegated to 2nd place. 👍

Also, thanks @lowrider57 for your perspective and impressions as it got me interested enough to buy one. It’s everything you mentioned, and more, without one bit of negative to relate.

It’s the most realistic presentation I’ve heard in my room. 

All the best,
Nonoise
 @jerrybj 
I also bought a discounted 0.5 from Audiogon. I think the buzzing from my amp caused the harshness in my system on my earlier audition. So amp is in the shop.

Good on ya, @nonoise .


As much as I liked what I heard, it was when I retired to watch some TV, which is on the same line as my audio gear, that it hit me. 

I need more.

The picture had an unusual sharpness that still retained a natural look. The colors and contrast didn't pop as much as one would expect but were nonetheless more contrasty, defined and again, more natural looking. I liked it so much that I went and ordered two of the B-stock units to add to my system.

Now I see what all the hub-bub was about when High Fidelity first came online with their products.

All the best,
Nonoise
So that's why the MC-05s in the classifieds disappeared.

I only have space for one MC 0.5
That’s probably a good thing.
Still have to pay for Black Ravioli, and upgrade to 2 Mad Scientist Nitro Nano power cables.

Where is best for the MC 0.5?
In the ’2 outlet’ power socket?
Then would have to run the amp through the power strip.

(Power strip also has the Dac power supply, Akiko Triple AC Power Enhancer, Russ Andrews ’The Silencer,’ iFi AC iPurifier, Blu Ray player).
They ran out the first time last week and got more in stock. Hopefully, it'll happen again.

As for the placement, I used an open outlet socket to get the results I got. I'm lucky in that although I live in an apartment, my two outlets that serve my audio/video needs are the only two on that particular breaker.

Since I have only one available outlet left on a power strip, I was advised to just get a 2 or 3 way (t-shape) adaptor for the wall outlet, running two MC-0.5s on it and use the third on the power strip. It will all work out the same due to the proximity of the devices and the isolation of them as well.

All the best

I took a look and there's still some for sale if anyone's interested. 👍
