I would say that if you are looking at high end products… say in the $5K to $25K… tube products are likely to sound better.
in my previous reply, i said under $5k...and probably even closer to $2k would be more likely at the moment.
Also, for use to be helpful, if you would put some quick photos and your components under your UsrID… under virtual systems, we can be tremendously more helpful. Lots of times a question comes in about a piece of equipment, but the answer is about how your system is set up or your venue. Very helpful.
setup is fine.....as i said, there are room treatments, speakers have been moved in every direction possible and the end result is always the same : center imagining and that is where it ends. i would like more soundstage, hence the preamp question / post.
