Good info, guys, and just the kind of feedback I was hoping to get.
@blisshifi, I can certainly understand why you would think the Platinum could be a better match with my phono stage. The Allnic H3000 is refined in nature, as you say, and most people describe it as being on the warm side of neutral, attributes that could synergize well with the Platinum's higher resolution. But after nearly a decade with the Allnic, I can say that the disconcerting thing about it is the extreme degree to which its sound is dictated by its external power supply. Rolling the rectifier can radically change almost every aspect of its sonic presentation. And the warmth people hear? A lot of it comes from the rubber footers on the PS. Not the phono stage itself, mind you, but the footers on the PS! I actually don't love the H3000 with the stock footers on the PS, finding the sound a tad bloated in the midbass and closed-in on top. Replacing those stock footers with Stillpoint Ultra SS (only on the PS), however, really opens it up, increasing HF detail, air, and neutrality, and thinning the bloat. Albert Porter turned me on to this tweak and he was so right. It's the only place I've ever liked Stillpoints. The improvement is big but not without cost: some of that desirable warmth and bass-weight is lost; and the overall tonal character shifts upward a bit. All this is to say, given the way my H3000 is tuned, I am a little apprehensive that the Platinum could tip it a little further in that lean and revealing direction. The Gold, with its musicality and body, and perhaps minor softening of edges, might turn out to be the better compliment,
