Over the last 15 years I have owned Proac's. I had the response 5's powered by BAT tubed mono's then the BAT 250wpc SS amp. Loved those combo's but felt the 5's were a little too big so I sold everything and got the 1sc's and a Cary 300sei which was midrange magic. I lived with that combo for about 5 years and sold the Cary and replaced it with a Classe 100wpc SS amp. That combo was nice but as my music preference changed I felt the need for a deeper bottom end. One of my closest friends is a Proac dealer so I (for the last couple of months) started researching the new Proac line. I was torn between the D48r and the D30r. My room is aprox. 28'L x 17'W x 8'H. I was looking for that Proac midrange with a deep controlled bass. I finally decided on the D30r's (I was so worried they wouldn't have the bass I was seeking). I have had the D30r's now for 2 weeks and am totally blown away with them. They have the lush midrange and great soundstage of the 1sc's with the best, deepest and most controlled bass I have ever had. I have a Classe front end, Marantz preamp, Classe 100wpc SS amp with Nordost PC's, IC's and SC's. I couldn't be more happy. I think the D48r's would have been too big for me and my room. My musical tastes are R&B, jazz and some rock/blues....Ron
