I have the LAP-150MkII which I wanted to upgrade to the 300. However the phono section in the MkII doesn't have enough room for the Auricaps so I upgraded to the Sig. as I don't want want another piece of equipment around as I don't have room for it. I am very glad with the Sig upgrade as I feel it brings me 90% of the way to the 300. The best preamp I have owned. Don
