The Best AC/ IEC power plug combination. Oyaide, Iego, Neotech

I use IEGO (Gold) male and Furutech Fi-28 Gold IEC on my solid core power cords used on BAT vk-600SE, Einstein The tube MKII and Mcintosh CD player, with a great result.

My experience with IEGO Silver (Male/IEC) as well as IEGO Gold IEC, was not enchanting and found it too bright with a lack of BASS. This is based on my experience with different power cords (Furutech, Transparent Audio, Tara labs and Neotech).

IEGO Gold Plugs are very dynamic and well extended on High Frequency, nice midrange Fr. as well as very good Bass. Beside, they also have an EXCELLENT articulation of music notes especially on piano, strings and voices. This is not the case with Furutech Gold plugs or Neotech which have more warmness and could loose some HF details. Furutech Rhodium male is very neutral and could exhibit some brightness.

IEGO ppower cords are also very good with IEGO Gold Male and Furutech Fi-28 Rhodium.

Neotech NEP-3003 MKII (hybrid) power cord is a very good PC too with Neotech AC (gold) plugs or IEGO Gold male and furutech Rhodium, really 3D effect and detailed.

Hope that would help...

@richardhk,

Regarding IEC / Ac male plugs influence on sound quality, there have been some discussions all around. we are talking about 1 to 3 meter PC.! I found more neural IEC plating plugs, would offer better balanced result. Even IEC pure copper (Furutech Fi-15), would sound fantastic in combination of AC gold/Rhodium Male plugs (on pure copper PC)

Audioquest power cords with modified AC plugs are very good, well detailed and well defined images as 3D. I still have one NRG-2 and NRG-4. I would suggest to send them for Cryo treatment too. It will improve its capabilities by 10%-20%. The only problem is that they are 14AWG PC and could not drain enough current for my amp or my preamp! Of course, the Storm series have higher gauges ...

IEGO 8085 gold male would work out fine with any Rhodium IEC. I am not familiar with Oyaide F1, I think your ears are the best judge.  

cheers...

I use Neotech NC-P313 Male AC and compared with IEGO 8085, it presents a warmer sound and less details. It is a good choice with Neotech Hybrid (copper/Silver) PCs but not with copper PCs like NRG-4.

Based on my experience, Using IEGO AC male plugs with Furutech Receptacles (GTX-D Gold or Rhodium) as well as Furutech pcs (like Alpha-3) is not a good idea. It kind of slows down the dynamics. Perhaps it is because of non-compatible plating process that two companies went through.

Furutech IEC plugs using based metal as copper (Fi-15plus (C., G., R.) Fi-25 and Fi-28) are better than other IECs brands. They are very good match with IEGO 8085 Male plug.

BTW, what is the PC brand that you are using?
 
Sorry, I never used Oyaide plugs...

cheers...

- AQ NRG-4 has multiple noise dissipation layers, it would be a better choice than 3xNRG1.5. Power cord built up against RFI is more important than purity of its copper conductor. 

- IEC Rhodium is not a bad idea. I also tried IEGO 8085 male with Fi-15plus Rhodium IEC ($50), Plating is done on pure copper conductors. IT is a good match.

- Furutech Fi-15 copper IEC is also a good choice. I had a good result using them.

- I didn't have a good result using Silver IEC (IEGO or Furutech Fi-11 Silver IEC).

After all, it is all system dependent.

cheers.
