Esoteric X-01 vs K-05...

I'm in the market for a new CD/SACD player to replace my ageing Modwright 999ES. I've been looking at used Esoteric's (K-05 or K-03). The K-05 is more in line with budget realities. I have noticed a couple of older Esoteric
X-01's for sale. Just wondering if the X-01 would still be considered a viable choice these days. Has anyone had a chance to compare an X-01 to a K-05. Any feedback would be greatly appreciated.

Thanks
