Hello Klaudio,
It's an interesting hobby but don't take it too seriously, you'll find yourself searching for a truth that doesn't exist. Remember it's all about you. The Krell is a love hate relationship for most. Some hate (many haven't listened) and some love (many haven't listened). Trust your ears. There is a lot of marketing in this game. Krell mentions class "A" without the addition of biasing and Musical Fidelity suggests their amplifiers can handle peak currents at 75amp. Both are laughable and often meaningless statistics, both are in the business of selling and marketing general ideas. Each are successful and it happens in all consumer products. And most seem to forget these companies are in the business of selling electronics and not art.
I would recommend perhaps keeping your MAC and buying an external DAC. There are many more options and perhaps a cheaper alternative. If you are set too a one box solution then I would recommend an Ayon CD-1. For several years now I've tried (through casual listening on other systems) to find a digital product that beat my older Meitner gear and I think I have. The Ayon is a real gem. It has the same sonic analog virtues as my Meitner stuff but with much more detail. I haven't heard a better digital playback system. At least not in a home setup. I also believe the Ayon uses XLR outputs (I listened single ended) which would ease any concerns when connected to the Krell.
