Further on the DX300 Amp 12

Head pie 0



Posted on head fi just now-


regarding PO (i havent tried the LO except with iems accidentally at first - no hiss and volume is lower than PO).

At around 36 hours now. Aiming for around 75 hours for proper impressions and quick comparisons to Amp11mark2 and DX220/amp8EX- maybe Max also.

development seems to be Amp8 - Amp8EX- DXMax based on Amp8 - Amp11 - Amp12. All retaining a certain Amp8 flavor but developed and getting cleaner each time.

Clear is how i describe it, another person i message chatted with said Clean with no prompting.

No hiss on the LO. Very black. PO has some Minor hiss. Initially more but decreased after 24 hours. Not an amount that gets in the way, hardly noticeable imho. This is t

Flicking through the Filters. Mostly using the Slow roll off 2 & 4 with some NOS. Needs more hours to settle just like other amp modules. At least we have data that shows the general sweet spots as one edges to 200 hours or so. @jamato8 thanks parallel journier.

its very listenable. Neutral, not neutral. It does not have that slight coloring that amp11 has.

agreed

Next up is to get some more hours on it and then comparisons.

Its a tricky amp module to discuss...because it just ‘is’. In it clean presentation. Its not one to gush about...rich this, wow that...the wow factor is more subtle.

Using CA MW10 constantly as a base point of sonic continuity up to 75 hours.



Nothing to report
At around maaaybe 65 hours

a few sonic changes have happened and stayed or moved on, less refinement then back to refinement, more low end then less then medium. Quite the adventure.

its maturing well would be the right angle to view it.

i think 100 hours rather than my initial usual 75 hours would be a better time to report more fully and accurately.

I’ll be back.


Noise testing etc
