Old Furu downstream now

I went for putting the old broken in Furu Cu in my Jon Risch Digital Isolation Transformer. That feeds both my DAC and my CDP. Not that I could justify the digital over the analog in this case, but the Iso Tranny is less of a knuckle-scraping job than the DIY power strip feeding my analog gear.

OK, my impression right away is that it works. Though broken in already, the Furu took maybe 5 minutes to mellow out and settle in (it had been out of the juice chain for about a week now.)

First noticed that acoustic bass srtings were more defined, taught, better attack. Then all strings and piano were better defined. Then found that voices in mids were great. Instruments started to come in clearer and a bit more lifelik, for example woodwinds like the sax, so no loss there. Then heard much clearer cleaner HF in the brushes on the crumheads and in cymbals. Nicely defined, properly metallic, came out of the background where they'd been hiding a bit before with the tweaked P&S 5262 there; no brightness or glare or tizz. Just pretty nice overall and a definite improvement, though not as strong as putting the Oyaide in the wall. Cannot tell any difference in electrified instruments, but do think I picked up some subtle odd background sounds from a Hammond organ on one track.

FYI, the iso tranny had a 15 amp P&S that was tweaked and well broken in with a metal plate cover and a magnet on that. I replaced the metal plate cover altogether with a 3/8" thick carbon fiber blank drilled out for the plugs to pass through. So there is probably some improvement due to the change in the plate covers too.
