Hi newmguy:
Here's a link to a previous thread which discusses the various issues you might be experiencing.
http://forum.tvfool.com/showthread.p...hlight=preamps
In the thread, there is a number of links to various preamps/amps that might suit your needs. I think that some posters here would recommend Kitz Technologies amps for their robust performance and low noise figures. There is a link in the thread to their website.
Please let the forum know how you come out. I think it would be of interest to many here.
All the best.....
