Opinions? Bit of a compromise...

Hi all,
Bit of a noob here, just after some feedback.

I currently have a NAD setup - C320BEE amp, C521BEE CD player, C422
tuner and Kef Q1 bookshelf speakers. It's a good setup, but space is
becoming an issue, and I'm considering an Arcam Solo to replace the
separates, retaining the same speakers.

I'm aware that the Solo will probably be a compromise and not sound as
good as the separates, but how much will the difference be? And how
does the Solo work with the Kefs?

Thanks
Nick
