Chaps, just a thought, how about we run a blind test? I’d be happy to host for say 5-6 people.
My system is fairly decent and Jason could bring along a couple of RA items to show us.

I would love to be involved in this. As it happens i have 2 RA powercords, along with 2 Naim Powerline Lite cables as well.
If you wanted me to, i could also bring my Airlink Balanced power supply. If Jason was to bring along all his mains conditioning bits, it would be very interesting to compare all of them against a balanced power supply on it's own with no mains conditioners.
 
Hornets ginger could bring a Polaroid of his setup as seems showing it on here isn’t possible? :cry:

I actually do something like this, I have taken power cables to friends houses to try. I'm certainly interested in meeting up providing everyone was prepared to take the listening tests seriously.

The issue is i'm Nantwich, that's 4.5 hours drive from Surrey, so we need a location that's more central. I am interested in comparing the balanced mains unit someone mentioned to the RA passive power conditioners. A good location would be OCUK showroom, but they would never go for it.

Something you have not considered, your audio will be improved by these products, once you hear your improved audio you may want to spend money on cables / mains conditioning also. I can tell you it's a total rabbit hole once you start down this path.

Your offer of hosting and doing food is very good of you, but as said it's 4.5 hour drive for me.

What RA power cables do you own? I have Yello powers, Classic, High Powers, References and a Powerkord 300, everyone I purchased pre-owned. I own 13 RA power cables, 9 are in use at the moment on various gear.

I also have some more entry level Audioquest cables I purchased from Peter Tylor in a clearance sale, the construction quality is good on them, they are still better than a $5 stock PC cable, but the improvements from the RA cables is more.

Makes sense. I'm not sure that I'd be up for a 10 hour round trip just to listen to someone else's system.

Plan B. Have a look on Ebay and recommend something under £100 that you think could be worth the effort. If it's not too bad, I'll consider buying it just for the test.
After all, if it impresses, that I can keep and use it, and if it doesn't, just goes back on Ebay.

What components do you have? How are you powering them? Do you use a mains block, or plug directly into the wall? What interconnects are you using?

You have good stuff. Also you have a balanced mains unit, plus you have a dedicated mains line from the consumer unit, your already way ahead of most people.

To improve your system, first step would be one of the RA power cables going into your streamer / DAC. It could even be a YelloPower cable if you want to try for the lowest cost. The good RA cables you should be looking at High Power / Reference cables or above, with WattGates on them.

The second improvement is filter your ethernet cable going into your streamer /DAC. You need a very short Ethernet cable for side that connects to device, also you need to wrap it in aluminum foil to shield it. Don't listen to others on here, they work, if it's no good Amazon free returns.


After this I would look at RA power cable for your pre-amp, then a RA power cable for your amp. However the 2 things above will be enough to get you started.

How are you powering your components, do you go directly to the wall? Or are you using some form of mains block?

As a slight Audiophile myself (Valve amp with vintage tubes) and custom built speaker cabinets, I get a lot of why some of this is important.

Crap cables will cause problems, and a cheap upgrade to something properly made for the job can make a difference to the sound.

What strikes me as odd is all the talk about removing noise from the power lines. I run a double conversion pure sine wave UPS on my amp to get clean power...that's all that is needed with half decent shielded cables. Without it my amp would be subject to large voltage swings (not good for valves heaters!) and there is definitely noise on my AC from the Powerline network which is very audible without the UPS.


I would be interested in testing things with an oscilloscope but it's just not a rabbit hole I've gone down yet.

Good point as a ups should isolate pretty well (and you get quite a lot for not much cost with a ups).

I have 2 of these, one powers my Supernait 2, the other powers my CD5 XS.

Can i make a suggestion here guys ?
I live in the Midlands in Worcestershire. I'd be more than happy to host this if it means less travelling for most peeps. Obviously you would all have to put up with a Naim system lol....................but we all have to make sacrifices :D

They are old cables, but there still better then the Yello Powers RA sell.

They are the same as the RA Classic, they also use the same high purity copper with Kevlar dielectric as RA current line of Powerkords. The modern version of your cable is the Powerkord Evo 100.

I'll give you a tip to improve that cable for free. If the plug has not been opened in years, undo the plug and clean the oxidisation from the fuse holder and also fuse. You also need to gently press on the fuse spring bars as they slacken over time.

The IEC end, spray contact cleaner inside of the holes. Again if it's not been cleaned for years there will be dirt / oxidisation on the contacts.

BTW I use Halfords electrical cleaner to clean out all the pre-owned power cables I purchased.

I don't need any tips thanks @JasonM. I have probably at my age gone through more Hifi in the last 30 years than you have in your lifetime.
ALL my interconnects and mains leads are cleaned with ISO at least one a year and have been for the last 40 years.

To answer your questions:
- My processor is my pre-amp, streamer, and DAC. The source is my RoonCore, which I host on my PC. Short ethernet cable? Unfortunately, not really viable as it's a floor up and the other end of the house, meaning that there's one router, two switches and 4 ethernet cables between the server and streamer
- The processor is plugged into the balanced power supply, which then connects to the wall
- The power amp is directly into the wall
- The wall socket is dedicated for only use by the stereo components, i.e. it's a dedicated electrical circuit, fitted at the same time as the one used for the conservatory when we had that built. So there's nothing on that circuit apart from music components. Even the TV is on the normal house circuits

Being a little further down the rabbit hole, I can probably give you some thoughts but that's a separate thread :)

The short ethernet cable, I'm referring to a tail that needs to be added to that ethernet filter.

Going to the wall (as opposed to using a mains block) that is good in my view.

Your wall socket will still have some mains noise / spikes on it, likely from outside of your house. Your amp would most likely benefit from a passive mains conditioner.
 
When I last played around, I preferred the sound of my pre with a balanced PSU and the power amp directly into the wall. Haven’t actually tried it with the BAT, but my thoughts are that pre amps tend to be more sensitive and also that my balanced PSU might be unable to meet the transient requirements of the BAT.
 
on the Ethernet thing.

Is that running TCI/IP or UDP as the tranaport menchanism.

If it’s TCP then it’s error correcting and the data presented at the other end is guaranteed to be correct (ot not at all).
If it’s UDP then it’s not error correcting.

The digital signal being buffered before DAC reduces the impact of lost data etc.
If the ethernet is isolated, and the digital data is uncorrupted and buffered then there should be little audio impact if any.

It ia easy validaing the corruption - compare sending a know bitstream and ghe output.

It’s easy to isolate Ethernet (optical makes this even easier).

After which it’s just buffering the audio stream transported.
