There was some interesting discussion a couple months back on this thread about burn-in skepticism happening to "coincidentally" always be the changes that we
wish for, never negative. Wanted to share a small anecdotal experience to play a quick devil's advocate.
When I demo'd the Traillii 8 weeks ago, I loved the out-of-box DX300 warmer signature as a compliment to the R8's more stage, treble and airiness focused presentation. The pre-burned in DX300 had a much more forward, well-layered yet intimate lower-midrange and bass emphasis, which worked for when I wanted more "aggression" in my pairing.
8 weeks is a long-time in our fast-moving hobby, and although I
overall prefer how DX300 has burned-in to become more balanced since then, I do find it has approached closer to the R8 in terms of neutrality, which has me somewhat missing the synergy Traillii had with
pre-burned in DX300. Yes-the mids are still more forward and musical on DX300 than R8. Yes-the bass is still more textured and dynamic on DX300, but it's no longer the warm monster pairing I had prior, which was a guilty pleasure!
Nonetheless, today's pairing out of High Gain, NOS digital filter is amazing as a standalone. Excellent timbre, beautiful layering, and amazing bass-response. No complaints here! Just portraying how we win some and lose some
