This is the kind of post yo0u would see in Audiogon but I will not go there- those guys can be brutal. I am looking for an upgrade path. I have the full stellar stack with M700s and the P3. Speakers are LSA 10 Statements Oh and a Denafrips Iris USB converter. Got imaging space and dynamics galore. Recommendations to improve tonality is what I need. New Preamp maybe? I am a retired man don’t have the big bucks. Maybe a tube preamp? Budget 3,000?
