Have Linn Classik, upgrade to int amp & cd? Naim?

I have a Linn Classik and I was thinking
about upgrading to something like a
Naim Nait 5i and CD5i. I would be open
to other options except that it has to
be black and both by the same manufacturer
so that 1 remote runs both. I'm lazy.
buget is about $3000-$3500.

My motivation is mainly to get better sound.
Also considering a seperate Linn Amp and
running the clasik into it.

Does nait5i have a brighter or softer sound
than the clasik? I'm sensitive to brightness.

Thanks
Tom
