A week into using the HD-500 and it's safe to say, it's better than any HDMI adapter on Amazon!
Due to how well this little box has been working for my setup, and the need for other inputs to get some love on my XBR55X900H Bravia, I've purchased the AT-LINE-PRO5-GEN2 off eBay for $60. I'm hoping I can gift the HD-500 to a friend and also eliminate other equipment for my other consoles like Wii and CECHB01 PS3. One big box to do it all! I'll post my findings in here once it's installed and setup.
Another note: mClassic is amazing.
