@terry9 I did not know of others who are using the P'holz as a Arm Wand.
Did your experience leave you with the perception there was another level of detail being extracted (crud removed ) with this as the material.
Each Time I experience it in use as a exchange material to a material I am quite familiar with. There is a certainty a extension of detail is present and a new comprehension is created of the structure of the recording during the presentation. The other trait that is on offer, and one that takes a little extra time to convince oneself is present, is the added micro details to how the instrument has been used, or the Vocal Note Formed. This is a lot of improvement for a little bit of being curious and not with too much cost involved to step so far forward in a improvement. I find it hard to see this as a subjective evaluation, there are so many reports all making claims that have a cross over of information.
For those with a mind to produce a range of items for HiFi purposes, It is becoming a go to material now. Which is at this stage of being presented as material worthy of investigation, is now with about 12 years of forum promotion for the investigation into the usage behind it.
