DX340 iBasso developed Discret DAC, Easily replaceable batteries, Amp Modules! ***New firmware on 1st page. v1.04 local update. ***

If they don't fix these damn charging bugs there will be problems. I had them AGAIN on the new FW. Stuck at charging at 80% for 2 hours. Shut off DAP and started charging right away. I might return Bloom unit and sell other one and buy again in 6 months when all bugs are fixed. No question SQ is best ever and unit is well built. I noticed something else. IF your IEM is lacking in anyway you will hear it on the 340 because it reveals everything.

Notice "This post is about DX340" is now gone. Someone with ADMIN rights added it and thought it would be cute or something. Lets say I have one foot out the door with the site because of it.

Agreed! and I can not say enough good things about Dx340. I am eagerly waiting for Amp16 LOL!!!! we should be getting info about it in the next couple weeks or so

Right now enjoying the AMP14...curious about AMP16 (since it will be still an all-in-one device), but waiting eagerly for PB5 (which should arrive tomorrow)
Thoughts about your custom Ni-CD powerbank? Is it worth it? I have researched components to build a Ni-MH one based on AliEx components.
I'm looking into Eneloop AA accu Ni-MH which are 2000 mAh or Eneloop Pro which are 2500 mAh.

Also thinking that if I am to build one myself, I would do 2 sets, 1 in use and the 2nd for when the 1st is drained

But...is it worth it? Not sure how much time you can get out of it.
That's the big question right now...probably after getting the next cards that can make use of the 12V DC in it might make more sense...right now I'm planning on using the AMP14 as the regular card + use it's dedicated LO for feeding in the PB5.

 

[mattclarke18]

LOL, that's how I was yesterday waiting on the damn UPS truck...seemed like an ETERNITY....Didn't arrive till 8pm last night

That is LATE. I have learned with UPS if you pay $20 a year you can redirect your package to UPS store and get first thing so no waiting until end of day.

For LO why not use AMP15? IF you use with 4.4 port LO volume is better.

LO is software driven in AMP15, probably the AMP section of the card is differently build, and because all of this it's acting like a preamp and not a pure bypass of the AMP.
On AMP14 you get a dedicated LO, no more switching and you have fixed volume, you cannot control it on the device - which is great for external AMP like PB5 where you would control the volume just from it...no longer depending on extra 12V DC input for better performance (more power).

From my POV, AMP14 is a better LO card because of all of this. Schematic wise, LO on AMP14 bypasses everything, it just outputs from the DAC directly to the 4.4mm jack.

DX340 Amp15 NOT a true LO? I thought it was.

No, the AMP15 LO is a bit weaker than PO too.

The AMP12 was the one that had true LO mode.

Well, if you need 12V performances on the go. Then you cant beat the battery pack solutions . Whether it is Preamp or Amp usage. It is cheap and effective. Dont know how long it lasts LOL!!! Too many stuff on hands atm

Amp15 isnt software driven LO. It is just Preamp out as i posted previously. The True voltage driven stages are built in the module, that is Amp14.

Next moduled will possibly have an improved Line driver for LO instead of Pre out

Indeed, I'd very much like to have something like a level of the pack...haven't yet looked into that (need more time)...
When I was saying that AMP15's LO is software driven I was correct...in the sense where you don't actually have a dedicated LO 4.4mm, instead you have just one 4.4mm output that can software between PO and LO.

I believe all AMP modules that have 12V DC port will behave similarly to the AMP15 when it comes to LO, just my 2 cents.

Well, the LO can switch by software or via a transistors based on plugged port. They are the same. Amp13 is similar. Once plugged into LO, 340 says LO mode (it will refuse going into PO)....gain still affect loudness

The amp design architecturals is the decisive factor, not how the player switches to and from

There are many different ways tp design amps. Having DC In port doesnt neccessarily warrant the same outcome as Amp15. Though super gain may still benefit as even the Line driver stage can benefit from Fed with higher voltage and other gains will not if it doesnt do pre out

The 320Max Ti LO is also switching via software, sharing the same as 4.4 phone out....and it is a true line out FYI

LO on AMP15 4.4 port does not sound bad. Used in car system and did not have to raise volume in car system any higher. With 3.5 port I did have to raise volume a lot.

It shouldnt be bad. It is a pre-out, which is still a proper Line Out.

My D16 has LO from it Line driver stages, given that it is a dedicated DAC with integrated amp as a bonus.

Line out is also firmware selectable, sharing the same 4.4mm port. But gains is not affecting the PB5

Here is all the beasts working together. The Ibasso current Trinity

Portable anywhere, couch side, bedside, never lacking of power, or tubes, or needing powerbanks

I only use the best for my stuff. Please dont mind my obnoxious cables. They dont look good or kilobuck expensive. But their performances are Real, anyone can hear, and they selectively come from endless of my experiments with a lot of researches, works and $ invested over decades in this hobby

True and not so true.
Dedicated LO is different from shared plug with software switch. At least when it comes to AMP14 and AMP15 since I have both and have tested extensively between the 2.
LO software from AMP15 is preamped thus you can still switch between AMP gain.
LO hardware port from AMP14 is not preamped and it has a stable 1.8Vrms voltage always...there's no AMP gain available anymore - it does absolutely nothing to the output when plugged into the LO port.

Having the 12V DC available, iBasso took it in a different direction by giving us a preamp on the AMP15 card...I'm assuming same approach would be available on the next cards as long as they also share the 12V DC ... might keep the same implementation as AMP15 from my POV, we'll have to wait and see

No one said it sounds bad by any means...only that it's not a fixed voltage one and it's actually a preamp LO that is influenced by the AMP gain settings.

Exactly! So the AMP implementation on the AMP15 is totally different than anything that has been made available so far - it being preamped.
Stable voltage from my POV is everything so I don't have to worry about settings volume to max/min, or adding additional power via 12V DC in to get the best out of it.

 

[Whitigir]

If they designed Line driver stage with optional Voltage gains, You will have variable Line Out voltage. Even if it is switchable from software. Amp gains wont do anything but Line driver stage Voltage gain will. That is 320Max

I never heared my Utopia 22 better then with DX340. There is air, big soundstage, all elements have that analog full sounding character. Absolutely amazing!

Good with trance/edm too
