Thank you guys for your input!
I have no way of doing an audition on the Klimax set, as none of my local Linn dealers carry them. I guess the only way to find out for sure is to buy them.
My current amp is a Gryphon Callisto 2200, according to the description of Linn's sound from your guys, I would expect Linn's sound will be leaner, but hopfully faster and more transparant. The Twin has only about half of the on-paper rated power than the Gryphon, but the Klimax set costs more than double, it will be interesting for me to compare.
I am shopping for a used set of Klimax, so in case it does not work out, I will be able to sell them w/o too much loss. I am also hoping my Wadia 270SE transport and Reimyo DAC would help out a Linn's set in warmth and weight. Again, There is only one way to find out!
