By using Nordost Component video cable, Krell DVD Standard's picture has decent red, green, and yellow color that my Denon-5910 troubling catching up. The Krell DVD Standard would probably was considered one great player at its time but since it doesn't have HDMI I find that its picture is not as clear and sharp as my Denon-5910. If you don't care about 1080p picture quality then it's alright for movies and music concerts, I guess.
For 2-chanel listening, Krell DVD Standard sounds alright. People called it super details and that's a good thing but I'd called it bright. All of my music seems to move really fast and short. Yes, I can hear every notes of music almost clearly but I end up listening to my speakers/system the whole time rather than enjoying the music itself. I personally like my music soft, and slow; a romantic kind and the Standard does not fit in this catergory. The Standard will not play SACD or any burn CD/DVD. Denon, however, is a bit more friendlier in this department.
If you own a DVD Standard, you may not need any home protection such knife, fire arm weapon... you got its remote controller. It's heavily weighted so if you aim it right and pitch it correctly you def will take out/down the intruder with its, seems to be, steel or brush aluminum remote controller.
Also, have to be very careful when work behind any Krell products. Make sure its power is off and give it a moment long enough so all the capacitors be discharged. The Denon, again, is more reliable in this department.
To sum it up No, I would definately not paying $8K for it. Just like Nordost, Krell is a big name and it has the power to lure new audiophiles into it like a magnet. Its sound is very unique, very diff, very American. Unlike the "English sound" that I'm very much more into.... So, if you are happy with your KAV-400 intergrated Amp and your component video output, the Standard may fit you well.
