Single box better??? No, not at all. My Empirical Audio and server sounded much better than any one box I've ever heard. I'll be very honest right now and I know I'm not the only one who feels this year, but I like the sound of the Empirical with my current server better than the DCS Rossini. I'm not a DCS fan, but I'm familiar with many of the CD players or CD players with digital inputs and none of them have sounded as good as many of the DAC's I've heard. The Krell was out in 2012 and maybe earlier. It's very dated right now. The Ayre QX5 is using a chip that hasn't even been fully released to others yet and it got custom filters just for Ayre. The ODSE/SE I just sold is unreal and the soon to be released ODSX will be THAT much better I'm sure. Bricasti M1 SE is also updated and outstanding. There are way too many great sounding DAC's in all price ranges. As for servers, there are the custom made ones that fix all the problems that CD players have had. Sorry, just can't buy into a CD player right now.
BTW, I have heard that Krell on many occasions and never was able to warm up to it, but that's my ear. I'm happy that you love it and will never want for any other digital again.
