Just added the LPS-1.2 into my Matrix - DS DAC - headphone system earlier today. Wow what an unexpected improvement in sound quality! Years ago I had an Iso-Regen and LPS-1 with my speaker system. While I “thought” I could hear an improvement with the Iso-Regen, I could never discern a sound difference using the LPS-1 or the stock wall wart. But the LPS-1.2 into the Matrix has really transformed the sound to the upside. Using the WWPS (1M) HDMI for a couple days now, the sound is definitely cleaner with a bit more extension at the extremes without any high-end graininess. The LPS-1.2 has added weight to the music but has not decreased the clarity. In fact, it may have polished the notes a bit. The bottom end has really improved too. I don’t know the technical reasons why, but I am enjoying it immensely.
My analogy to describe the changes I have heard is this. Imagine a page of the conductor’s score from a complex symphonic passage, maybe a full orchestra allegro movement of Wagner’s. Originally what I was hearing was equivalent to that page of many individual notes looking like a high-quality, hand-scribed copy in black ink (seemed great to me at the time!). Add the Matrix and I now see a 300 dpi printout on 20 lb / 92 brightness printer paper – much better compared to the original. Add the WWPS HDMI and it changes to a 600 dpi printout on 24 lb / 96 brightness paper. Noticeably better! Finally, with the LPS-2.1, its 1200 dpi on 28 lb / 100 brightness photo-quality paper. Itchy-Owee what a beautiful presentation. Irrational exuberance? Maybe. But I’ve gone from being Happy (H) with the sound to being H^3. Thanks for all your helpful guidance and suggestions.
