TAD M2500 amp - Power Cord warning

Hi Everyone:

I would like to upgrade the power cord thats connected to TAD M2500 amp with one of the aftermarket power cord from either Audioquest or Siltech(Ruby Mountain). My question is 2 fold (The inlet on the amp is 2 pronged).


1. I see the following statement in the user manual for m2500. 

        • Although the power cord to the unit is removable, do not attempt to use a power cord other than the supplied cord.


Why would they print such an explicit warning? I tried to see some pictures/videos when this amp was used in a TAD demo room, but couldn't find any that shows which power cord is connected during their demo.


2. My second questions is, can I use c15 plug to connect to this amp, even though the inlet is only 2 pronged. I think my second question could be already addressed here.

1 - Usually this is because those power cords can be unusually thin gauge.  So long as you stick to 12 gauge you'll be fine.

2 - Yes.  If your amp has 2 prongs, it is double insulated and does not require the ground safety wire.  however, shielded power cables still can reduce RMI / EFI noise.

Yes the 15 amp outlet is fine. A higher amp value is ok, lower is not..
EX. Equipment  rated at 300 watts, max amp pull 4-5 amps. You can use a  120VAC/15 amp/1800 watt, 3 prong plug. (normal house hold stuff). Your 2 prong stuff will be fine...

 Whether it is 120VAC and stays there, that's different't too, is there surge protection?Those thing can be an issue to..

I would think that you can use any power cord you want that has a three prong power cord as long as the ground prong is removable or you can use a cheater plug which allows you to go from three prong to two prong.

I think I missed the point here, if you are handy enough to install an IEC chassis inlet receptacle to accept any three prong power cord on your amp would be a solution, but you would have to enlarge the hole to accept it and may be worth it in the end or an adapter if available.

Thank you Erik, Hvymec.
@phd, the 2 pronged male inlet on the amp can accept the 3 pronged female plug, but the ground plug is not connected on the amp side. It will be connected to on the AudioQuest Niagara 5000 side though.

Anyone with a good result from changing the cord on TAD M2500? Which cords have you tried and liked. I changed the original cord with AQ Z3 yesterday, just to test it.  I thought I heard some improvements. Although that's not the final cord I would go with.
