Obviously (for their target market at least) the cost is a non-issue. Either that or their priorities are strange. I can't imagine ever spending more than 1% of the cost of a thing on decorations for it. The luxury market is quite different... to some it makes sense to get a $600 smartphone covered with gold and diamonds for $10K more. Pretty sure it doesn't work any better either - in fact it probably gets slightly worse reception. LOL

Well, if you want to pimp it out, you can always add your own Techflex:

These tend to do better in Non-blind tests also known as sighted testing.

I use paracord for PC sleeving... softer and better color range IMO. I think they do better in non-blind testing as well. Probably get an extra 100MHz on the CPU just from that. :cool:

But does the IEC power cord that came with your amp, DAC, etc. adequate? If not, what would be a sensible replacement? What is the Blue Jeans or Mogami of power cords (if such a thing exists)?
They should be adequate. That said, for high power applications, I plan to test a few alternatives.

Considering that high power cable rise temperature and change properties a little can be a good idea to have a bigger cable for high power equipment ?
Just to avoid temperature rising. I think that we'll never see that in the dac output.

It's theoretically possible I suppose, but again raises the question about engineering/manufacturing competency. As seen in the examples just in this thread, it's either the same price or a very, very slight increase to provide a larger gauge cable (especially if purchased in bulk). If that extra few pennies was more important than adequate power delivery... then they almost certainly went cheap in other areas of the design. That is way more likely to cause audible problems - that no cord will ever fix.

All of the subs and amps I've ever purchased (as well as PC power supplies, etc.) came with fairly beefy cords (12-14 AWG). However, all of the source components came with skinny ones (18 AWG at most).

With some of the luxury cords, I wonder how much of that garden hose size is just insulation or fillers... is the actual wire used even the same gauge as the cheap cord that came with the amp?

A not too special power supply will make that inconsequential.

I wonder what power cable this guy uses with his personal transformer.


With all that clutter and reflective surfaces in the listening rooms ... one has to wonder why they even bother with such extreme measures ! :rolleyes:

Ha, the irony of the gentleman's initial comments in that video "I found that I had long listened to music filled with noise. I could not stand it anymore."

While the image has him putting a record on his turntable. :)

Well, there's your noise! If you are that allergic to any background noise, you shouldn't be using a turntable. It seems to defy plausibility to me that whatever he did for his electricity to lower the noise floor would have been audible through the noise floor of his records. (Unless, perhaps, if he had truly execrable electricity and equipment with poor filtering and so was actually hearing significant AC noise I suppose).

If your looking for a inexpensive upgrade, Monoprice sells these 15A 14AWG cords. I bought 2 to upgrade and lengthen the ones that came with my switching power strips. $5.00 for 6ft.

It seems to b a common thing with Japanese audiophiles having the most expensive, boutique, modded and generally over-the-top gear, but placing it in tiny rooms or rooms without any acoustic treating.

Amir, your thoughts on the 2nd video?
The online service I was using to capture the video no longer works and is asking me to buy some app to do it. I am not going there so nothing from me unfortunately.

download link for the video: (so you can store it on the PC and analyze it)

will probably only be there for a few days and then gets deleted automatically

I am starting a company selling audiophile rotary converters. We used these on the British Antarctic Survey ships when I worked for BAS and the scientists all agreed that veils were lifted and that their scientific instruments had more rhythm,pace and slam when fed by the clean supply and that it was like being moved two rows forward.

But ... but the Earth is flat ! How can the Antartic be real ? :D:D:D:p

Down-sized versions of these can get your supply power factor to maintain constant unity. No more lagging(slow) or leading(fast) supply current. :facepalm:

Great... however after putting one in my yard, the bigger problem will be if I get to keep any of my gear in the subsequent divorce.
