linn kairn preamp vs VTL TL-5.5

should i sel/trade my linn kairn preamp w/fono & brilliant p/s for a vacuum tube logic VTL TL-5.5, w/fono? if so, why?
The 2.5 TL is just as good and I'm selling mine for $1000, only difference is the seperate power supply and face. Otherwise the two units are identical
tbonephile, my experience is that separate p/s can make a *big* difference in the sound of a component. does your tl-2.5 have remote & fono stage? why are you wanting to sell this - getting a linn kairn? :>) i still need vtl vs linn info. thanks, doug
Mine has remote no phono selling in order to get headphone system
