My post came across as ill-mannered and I apologize. What I meant to say is that the Model 6, which retailed for over $16k when it was introduced ten years ago, occupies a different market segment than a speaker that retailed for $3,500 -- that is what I meant by "mismatch". I meant no disrespect to B&W.
When run with the battery power supplies and with fully differential balanced front-end equipment, the Model 6's are bested by only a couple of solid-state amps. They are not, as one poster above stated, bass challenged -- they can swing 35 amps continuous (few amps can do that). Rowland 6/8/9 have trouble with bass? Sir, with all due respect, you are quite mistaken!
Your question: the sound signature of this vintage of Rowland? Very high resolution, warmish mids, powerful bass, slightly truncated highs. Overall, musical. Also, great build quality and not ass-ugly like a lot of equipment.
