Shahed,
Like you, I listen to a variety of classic/indie/prog/folk rock music from the 60's through today. No jazz, no classical, no metal and no Black Sabbath style hard rock. To give you an idea, some of the new bands I listen to are The Decemberists, Death Cab for Cutie, Arcade Fire, The New Pornogrpahers. I also like the Beatles, Doors, Clapton, Tom Petty, Procul Harum, Yes, U2, The Moody Blues, Pink Floyd, Jefferson Airplane/Starship, CSN, Neil Young, Neko Case, Wilco, ELO, etc. I have the DA-1.1s with the AP crossover. I also have a large room. I love the speakers. They throw a wide and deep soundstage with excellent imaging, dynamics and detail. Vocals and accoustic intstruments sound natural and real. I bought the Da-1.1s because the off set tweeters provide a wide sweet spot. All of Lou's speakers are excellent for acoustic instruments and vocals.
I have heard the DA-Rma's at Lou's and in a couple of rooms at RMAF and they do a great job with all kinds of rock music. You might want to check out Lou's newest model, the Athena.
