Hi mattmiller ;
I agree , the Primaluna stuff is quite nice .
Actually some do use a preamp on their integrated . They usually start out with the integrated . Then , to improve the sound , add a preamp . Most integrateds have a dubious
gain stage at best and rarely an all out pre circuit such as a stand alone unit would have . It's usually worth the effort and cheaper then starting over .
I use Reference 3a Di Capo i's .
Happy Tunes .
