Ref 5 is very old now , at least 10 years . even the 5se is getting old . 5k might be under budget for one of them . ls27 rarer than rockin horse ... oxford audio have a ls28 they might let you try . they have tried to sell it for months now , one went for 3k though recently on ebay
I would echo geoffs thoughts too
you could add a mfa baby ref to your list . thats an amzing pre amp . a few about but often no remote
ou might slip, you might slide, you might
Stumble and fall by the road side
But don't you ever let nobody drag your spirit down
Remember you're walking up to heaven
Don't let nobody turn you around
… Walk with the rich, walk with the poor
Learn from everyone, that's what life is for
And don't you let nobody drag your spirit down
