On my RS151 I have the following options:
• Minimum Phase
• Linear phase apodizing filter
• Linear phase Fast Roll-off filter
• Linear phase Slow Roll-off filter
• Minimum phase Fast Roll-off filter
• Minimum phase Slow Roll-off filter
• Minimum phase Slow Roll-off low dispersion filter
I’ve tried to detect sound differences among them through many listening sessions but, maybe due to my “old boy” status, I was unable to appreciate more some options than others according to my personal sound taste.
Is there any document describing the filter options’ sound characteristics applied on the RS151?
I would like to identify the one that makes high frequencies more enhanced, more sparkling, a bit bolder/sharper. What’s, in your opinion, such an option out of the 7 available?
