Integrated Amp Utilizing 2 Prong Power Cable

Greetings,
My new Yamaha AS2000 integrated has an atypical 2 pronged IEC and stock 2-pronged power cord rather than the typical 3-pronged grounded IEC and power cord.

Are there any detriments to using any of my aftermarket 3 pronged power cords with the AS2000?

Do you know of or can recommend a quality 2-pronged aftermarket power cord to improve on the stock power cord that came with the AS2000?

Thanks
