I have the 3500P and am very happy with it. I just asked about the 4500 and they are back ordered to January 2023. I was told the 3500 can more than hold its own. I had the Inakustic 2404 reference power cords going into a SR orange duplex box. I just sold all of my Inakustic cables. For the time being, I have a DIY Helix Dueland power cord but I have a feeling I am going to end up with the Takumi.
If I do I feel like I need three Takumi's: One for the 3500P, one for the Lampi Horizon, and one for my Lucas Audio Music server. That is a major investmentand I am not sure I could hide that investment from my spouse, LOL.
