Erik, I agree with your assessment of the sound of the FR filter on the Brooklyn. It does accentuate the leading edge of notes and attack more than the SR or MPH filters. If I am listening to a forward or edgy recording, I like the MPH or SR filter a bit more, but the SR filter is not quite as extended in the upper highs.
Be sure to try a different type of wire from the heavy 14 gauge speaker cable going to the Brooklyn from the power supply. I found the heavy gauge wire to make it sound dark and overly warm. I know it sounds silly, but the cheap, black 22 gauge stranded copper wire you find on small, wall wart power supplies sounds much more neutral and better balanced all around. It beat out all of the various, expensive, ultra-pure copper and pure silver wire I tried. You don't need a heavy gauge wire to supply the Brooklyn. Try to keep the wire as short as possible too.
My local audiophile friend just ordered a second RS12A from Astron, and had them set it up to put out 19 volts so he could power his audio computer with it. They did not charge him extra for the custom set-up. It took a few days of constant use for his new RS12A to break-in and settle down, but once it did, he is enjoying the results. Leave yours powered up for a couple of days before any serious listening, and DO try that cheap wire!
