Wadia direct into amp, Sound a bit too lean??

I own a GNSC Statement Wadia 861 and run mine directly into a Boulder 1060 amp. I've tried many ics from Jena to Tara 0.8s(including MIT Oracle V1.1s, both single ended and balanced. I am currently using the 0.8s(balanced) and NBS Omega 1 speaker cables and now the sound is a little leaner than it was with the Tara "The One" speaker cables I was previously using. Whether you run balanced or not, there are a lot of ic and cable combinations that would minimize the harshness without giving up the definition that a high resolution system such as yours should be capable of. Before I would invest in an expensive preamp, I would certainly try cabling first. I am currently experimenting with a Purist Audio preamp(differentially balanced tube design)running balanced through the 0.8s. I then have my Wadia connected to the preamp via Cardas balanced cables. It certainly sounds different than it does when connected directly. I only went this preamp route because I was planning on getting back into vinyl and I needed a switching device. I have yet to hook up my analog system so now I'm really just jumping back and forth between the two setups. I don't think I have the ideal combination just yet, but somehow I'll figure it out.
