Used Audio Analogue, Wadia

I'm considering an Audio Analogue Maestro or a Wadia 830 to upgrade from my Rega Planet 2000. Lately, I've seen them both for around $1,600 used.

My all Acoustat system: TNP preamp, TNT Trans Nova 120 amp and Spectra 33's.

Any other suggestions in the $1,500 - $2,000 range?

Thanks
