I don’t have dx300 yet , and from what collectively I have seen, look like 100uF/10V Fine gold series, which is a very well known Audiophile grade Nichicon.
While it is fun to look around, please keep in mind that these Fine Gold is highly praised by many, including Sony who uses it in their utmost marvelous DMP-Z1.
I had a couple PMs asking me about my Statements previously about Dx220MAX being so good, and priced at $1,800 while Dx220 is $1000
and a watered down version from MAX. Now, people may misunderstood me, then allow me to clarify. What I meant is that Dx220 could have and should have this Dual batteries system (not small components) since beginning and raised up the price , but it was too large, and the pricing may put people off, so IBasso saw the market that would welcome Dx220 as a portable player, and took it. Now, we are here, at the days and times where
Dx300 has everything the Max have including dual battery, and even further, with such Low pricing that people would think it is Mid-Tier and not High-End
The Dx300 under my point of view is a very High End player, and once again, I do not know how IBasso could have kept the price this low with all the new technologies being cramped onto it.
Now, regarding little capacitors, op-amp, small components that ”modifications” most than often bring “improvements”. Well, you have to understand that “improvements” is under someone “preferences”, while
IBasso have to cater to all of us as a “mass”.
Ibasso has never cheap out in components, and in fact it is more expensive to “modify” than to be “manufactured“ by “Ibasso”, and that was Proven by “Amp8EX”.
I could never modify an “Amp8EX“ for less than $400 in total prices while Ibasso was able to produce a limited run for “$250” including shipping by DHL. If it was being produced much more than it did, then there was no reason that Ibasso couldn’t keep it as low as the regular Amp8. That is the strongest proof I have to present to all.
Ibasso is the champion of Values for the money, no doubts, and that comes from my views. Modifications is to be different and very personal, and that is why I don’t run it as a business, but I publish DIY for all to cater to themselves.
I've to press the power button together with skip back button for 5 seconds, the release the skip back button (power button always pressed) and then press again on the back button?
..and I can't charge the player anymore..nothing happens only black screen. Maybe Paul from Ibasso has a solution? I hope i'ts not bricked..beautiful sounding player! Further help highly appreciated
