Holy moly, only 69 pages, for such a great headphone! That's ok, it's a great number anyway.
Speaking of numbers, rad-0 number 494, Pink Floyd, checking in. Proud to be part of such an underdog thread. Since my previous posts here, I have had my mega high end palladium coated silver cable reterminated for the Rads, with curious but satisfying results: the rad-0, with a dead neutral, dead honest, hyper detailed dac, amp, and headphone cable, still refuses to become boring or clinical, or unfun.
With my Hugo 2 and my equally expensive silver cable, the raw detail retrieval is really something special, but the Rads still retain a subtle, tasteful euphonic character over the whole frequency spectrum, one that doesn't sacrifice any extension top or bottom. Previously I had praised the Rad-0's versatility, and if anything upgrading to a more neutral, transparent cable has increased the versatility even more.
This might be a hot take, but I think the Rad-0 has the right amounts of everything. I don't hear it as "slightly euphonic" I hear it as Extremely Correct sounding. The bass for example, it's not excessive at all, I now have another headphone rig with significantly stronger, harder slamming bass than this, and it still sounds good. Likewise I've heard a truly, actually euphonic headphone, the Sendy Peacock, and that one still sounds good in the right chain. The Rad-0 is like a middle ground between everything.
I still can't believe I got this headphone brand new for 1800, what a deal! Now I'm going to spend more money on custom grills though, because I like it so much!
