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

[Whitigir]

Great to have you onboard as well Scuba! Glad you took my advice of ordering from https://ibasso-shop.eu/ - really awesome sync we have had with them, right before they got it we were fortunate enough that it wasn't all out of stock in the first batch...I'm in exactly the same delivery situation as you are




Hype is real...both within the team and outside. Really looking forward to increasing the adoption of iBasso gear. Can't wait for the new AMPs to also be made available as well as the compatible replacement face plates for existing modules.
Any word of advice/comparison you can give us tubes followers between AMP14 and AMP16?


What you're saying here is that a dedicated Linear PSU puts out a different sound out of the AMP card vs the included power supply for the card?
How much of a difference are we talking here in %? (if possible to quantify)
I do have a FiiO PL50 that I use with my XD05PRO that I can borrow.

I guess there are many factors in places.

But if you asked my instances specifically under quantiative % differences, then I will use digital filter differences by the Dx340 itself to answer

If the head gears permit you to tell the differences between filters and you observed 5% differences. Then under desktop mode and a dedicated LPSU, the scalability % would become 30%

The improved dynamic, punchiness, sub bass rumbles/ripples, the textures and staging are all improved. Keeping the same amp Gain level.

Now, back to the LPSU and many factors as I previously mentioned

1/ different LPSU will have different performances. Even the same schematic using different parts quality will be different. Therefore, I cant say for your specific instance, what you may observe.

My PSU is Sigma 11 with parts that I specifically selected by DIY.

2/ the head gears you hook up to the 340 may allow a different observations depends on it quality, sensitivity and it impedences curves. I observed these differences with HD800S

My question was more targeted towards your own experience with your own Linear PSU vs the included power supply that came with the DX340.
How much of an improvement did you notice there?

It's good to know what sort of PSU you have on your hands (have created in this case) just so that I can also then potentially compare with what I have.
But main important thing for me to take here is Linear PSU vs included power supply and how much of a difference do you feel it made when using one over the other.

 

[Whitigir]

It isnt exactly different sound signature. But it scalability which allow the amp to perform under a different pedigree and the many obvious improvements would be almost as if you were to use a different amp with different sound signature.

Well, you could simply say that it has different sound signature. But then again, as I mentioned, the LPSU that you are using will play an important role. Case in point is when you compare the stock adapter VS battery mode. They carry almost similar performances

 

[pmichaelro]

Gotcha! So in your case, simply put, it improved the already there characteristics of the AMP Card by scaling it further and probably "more easily" than a regular switch based power source.
Will give it a try when it arrives on Monday, hopefully I have the right barrel plug on my PSU.

Exactly!

I doubt it. The size for the DC input on the amp is the smallest I have seen. I dont think it is common enough to supply it to LPSU typically. But you can always order it

It took a little while for my 12 volt linear supply to come up to speed. It has a lot of super caps and hasn't been on for a long time. The difference now, even with the volume set lower that no PS or the included PS is very noticeable. The included ps works well and is nice and small. My linear supply makes the DX340 sound like a DAC with a separate amp. The sound is huge. Wasn't really expecting this as I stock, the 340 is already excellent but this does go to show, as Vince has said, what the DX340 is made of. Crazy.

Exactly! And I dont want to sound like exaggerating it. But it really is almost as if

I am very glad to hear that DX340 is living up to expectations, I look forward to trying it out in the near future

I wanted to ask a question about Rayteon JAN6418 tubes, talking about another recent product that also features them, someone seemed to downplay the proposition as it is an 'old and cheap' component

It is true that with a quick search you can see that a JAN6418 tube can be found for around $10 compared to the $50/60 that a KORG Nutube 6P1 can cost, so the question is this, is there any real advantage, improvement or differentiator in using KORG over Rayteon or vice versa??

Normally I think that how good or bad a component can sound depends on how well implemented it is, I must say that I am curious to see that suddenly there are so many products equipped with JAN6418 see SP3000T, M8T, AMP16 and Nunchaku among others so it would be nice to get some additional information

 

[phiemon]

Any comparisons with the DX320MaxTi?

They don't know what they are talking about. Tubes in the 60's could be had for 50 cents and some less. Some much more but the point in, 1000s upon 1000s were made, 100s of thousands, millions. So they are, for some, abundant and not being used so you can get them cheap but they are not a cheaply made tube. I have worked with tubes for many, many years, starting in high school and then the military and tubes can do things that solid state can not. The KORG is expensive because it is made now, these days with the current costs. A pair of 300B Western Electric tubes are 1500 dollars (they are currently being made, thankfully). Back in the day, they were an expensive tube, around 50 dollars. It all goes with the times. And they new tubes back in the day, the metallurgy, vacuum used etc., that is hard to match now. Oh, new old stock tubes of quality, I will take any day.

I have NOS tubes from 1929 forward. Excellent stuff.

 

[Whitigir]

The differences between tubes are still under a lot of discussions and developments from High fidelity community. Basically, bacl in those days, nothing could make one think about or discern much between the differences.

Just recently, digital high fidelity have surpassed the analog mediums. Otherwise, older technologies, it was what it were. The hardcore enthusiasts could always tell the differences. But as always, they got branded to be snake oils, shill and chill kinda stuff. Until nowadays, either it is the demands, or the quality, or both.... the investment back into tubes are getting into gears, and together with it, the investigations and development of the older ancient technologies.

There are many factors that effect the tubes. The materials, the gas, the grid structures, but most of all is the "Heat intensity"

Korg is a modern kind of tubes, while functioning under similar principles, just can not have the heat elements as the true Vacuum tubes . But just like everything else...there are pros and cons.

General consensus is that NuTubes are NOt as sweet or as musical as true tubes. The saturation points are also different...and so are the measurements.

But all hardcore enthusiasts....rather crave NOS tubes. For NOS tubes, 1 may be cheap, but using 2X while hand matching them...can not be cheap

@Paul - iBasso Can you please provide us with the actual plug size for the 12V DC port on the AMP15 card? This way we can also make sure to order to right type of DC plug adapter in case we want to try out Linear PSUs.
The most used one I came across was 5.5X2.1mm, not sure if AMP15 DC port has these specs or not.

Thank you in advance!

There are adaptors that fit 5.5x2.1 into 1.35mm. At least that was what I tried and made with

Yes 340 is crazy good even stock...with PB5 is another level...what if with a good Linear power supply to the 340 and lineout to PB5...I can't imagine really...it's madness!

Can I modify a Aroma Audio PS100Pro to use on DX340 for real portable ultimate endgame?!
