So it’s a definite, and clear improvement.
I went back and forth with tracks I’m very familiar with of differing genres. Whether by beginning a track over with/without the Palmer, or pausing the track and then switching back and forth. I did this with several tracks for about two hours this morning.
It brings everything into focus. So much so, that I initially perceived it as a lack of coherence.
All the detail is still present, but more precisely staged. Leading to improved imaging as well, though I’m not entirely sure how it’s affecting the soundstage (which could be due to the fact that I’m using LCD-X which are narrow in their soundstage, or if it just isn’t affecting soundstage at all).
Bass is more focused as well, with a possibly slight elevation (not boomy or anything, it could be that it’s just more focused but it feels slightly elevated).
Treble remained the same. Sharp, focused, and accurate.
It also brought about a much blacker noise floor. It’s dead silent. That’s one of the things that initially stood out, and why I questioned whether it lost any decay which I don’t believe it did. It’s just deep black background.
My guess without having heard one, is that it brings an RNHP closer to what a Phonitor sound is. More precise, focused presentation, with a pure, sonic accuracy.
Whether or Not this is better is really a matter of preference, as it did clean it up which kind of reduced it’s Analog charm. My advice is to try it out and see if you like it better yourself. It’s only $20 USD, which anyone that owns an RNHP should be able to afford.
For what it’s worth, I’m keeping mine connected.
