Hi Chuck,
I know Wadia recommends running straight into your power amp and I can appreciate the logic behind this ie most people aren't going to be too happy to spend as much again on their preamp as they spent on their Wadia and it does soften the upgrade path. However despite shortest signal path philosophy a top tier preamp will get a lot more out of your Wadia, at a price of course. After a long affair with tubes I finally went solid state, pre & power for accuracy. I chose the SMC VRE-1 over Spectral by a whisker but both are great preamps. A great improvement you can make to your Wadia is to buy a really good power cord difference is night and day.
