tubes can sometimes offer more depth than solid state depending on what you have now and if your speakers can show it to begin with.
soundstage
interested to know which component has the most effect on getting good soundstage..especially back to front.Also can someone enlighten me as to how speaker placement effects soundstage. I have altec horns. I get good side to side soundstage but very little front back. All opinions are most welcome. Thanks, Larry
