Like others I have been intrigued by the positive reviews for grounding blocks from various companies, but the prices are prohibitive. I decided to spend the extra $100 for the Ultimate over the Perfect as both reviews say it offers significant improvement. I am planning on plugging it into an unused RCA input on my Antique Sound Labs autoformer passive pre. I'll post updates after I get it, and have broken it in.
Yes, definitely. My experience so far agrees with the reviews. The areas where I hear improvement read like the proverbial audiophile checklist (transparency, resolution, texture, sense of space & air, palpability, dynamics, musicality, involvement etc.). It still has that bit of brightness, or glare, that I’ve learned to expect during break-in, but pretty much everything else has improved quite significantly.
