Its better than the old days when we had boomboxes and multi rack stereo systems.
i had to go to the store and buy a special cassette or vinyl 45 to update my system.
it was worse for those not living close to an audio retailer. They had to ordered theirs via the stereo companies via mail order.
It could takes months and sometimes by the time the cassette arrived there was a new update!
still not as risky as loading a video game with a 90 minute cassette and then the Pong game not loading and having to do it again...

in other DX300 news the gain settings for the DX300 i have on android and pure mango are correct.

Hiss
(*i am not a hiss meister. But i do get my ears tested every year).
i have tried several experiments with various earphones such as Monk earbuds, various Campfire Audio multi BAs, other BAs, some hybrid IEMs and also single driver IEMs.
I used Dire Straits as a nice quiet well mastered album to check for hiss
I would play the track for a few seconds (to let the amp kick in).. then stop the track.....Then up the gain to high and volume to maximum and check for hiss. A most extreme test. But it gives results. Then i dial down the gain and volume of course.
i found generally the multi driver BA IEMs to exhibit a minimum hiss. The level was not much different from high gain/max volume to low gain/ normal volume (around 35-45 depending). The hiss is not large, nor distracting. Possibly only noticeable to most by critical listening.
The earbuds, single dynamic drivers and hybrids seemed not to exhibit hiss.
At earlier listening sessions i did not detect hiss with aome of the multi driver BAs... So go figure.
Slightly more on 4.4mm than 3.5mm. I have not done a 2.5mm test set yet.
i did think it was less on pure mango - but mai brain could have been seeing double by that point.
But nothing major in my mind. Quite minimal and not distracting.

I still have the DX300 vs DX220 amp8EX notes to type up. But would like to include the Max in the round up.
