I've tested the 8805 in my system. It's an excellent processor for the cost. Large power supply and discrete analog output stages. Very good bass, punch and midrange body and fullness. However, it is voiced slightly warm with slightly rolled off high frequencies. It's a great product.
I haven't heard the MX123, but it's also very well built. I don't know if it's similar to 8805 or if it has better high frequency response. Either product will likely,
I wouldn't recommend Audioquest HDMI cables. They did not perform well for the price you pay. Audioquest interconnects and speaker cables are good. So are the power cables. There will be a million different opinions on the best cables and this is a "can of worms" question, lol.
I would recommend older WireWorld Series HDMI cables that do not have the DNA Helix design. The older Silver Starlight 5-2 or Starlight 5-2 or 6 are excellent. If you're on a budget, the Neotech NEHH-4200 HDMI is excellent for under $100 and will perform as good as the much more expensive WireWorld 7 Silver Starlight.
