The RS-1's are awesome, with the right setup, and very good with an average setup. While there may be better phones for complex, symphonic music, there is very little that's better for R&B, Jazz, Country and Acoustical music.
If that were not the case, why would I make so much of an effort to get my HD600's, and HD650's to sound more like my RS-1's? Although, I have to say, my Senns, are sounding very close to my RS-1's now... maybe better, but I don't think they'll ever quite have quite the organic texture and tone of the RS-1's, which their wooden sound chambers impart.
Though... they are overpriced, relative to their SQ compared to other phones. But... who pays more than $500 for them anyway (if you shop carefully) - which is not that much more than many pay for their Senns with upgraded cables and expensive amps to drive them.
No matter... the RS-1's are awesome!
