WOW £700 for an iem cable,, respect.

Hmm the cable only costed me around $540 tax included.
Best cables I've bought for my IEMs.

The thickness of the cables changed the impedance of the Astroliths and boosted the dynamic range.

At least you are right on the topic. The thickness dont change impedance overall by much but the impedance curves according to the harmonic contents VS the deliveries of the amplified signal behind it.

There are also other properties as well, such as the thickness and materials of the dielectric, the geometry of the braids that causes inducted capacitances and overall allowing the cables to have some inductance as well. But people who shook off the ideas that cables can affect sounds will never find out. Because they never cared

However, I dont believe in cables that cost kilo bucks. I rather invest in better power supplies, amplifications, converters...etc... But when I build my own stuff, they are all of quality components, even a plug or socket

I have a disease...and it is hard to cure me from it

I experienced a similar phenomenon with my 8-Braid Null Audio Thera cable I bought a few years ago, I was genuinely surprised the first time I used them, the soundstage got much larger and dynamics were boosted. For what ever reason I sold the cable and never had the chance to compare with the many other IEM cables I've owned over the years.

And just like my old Null Audio 8-braid cable, my new Lavricables Grand IEM cable exhibits similar characteristics such as boosting the dynamic range of my Astroliths.
On the DX340, as soon as I swapped the cable to the Lavricables, I noticed that I could raise the volume a few more steps than with the stock cable which indicates a boost in dynamic range. Soundstage got much larger, details more splashier and dynamic.

This Lavricables Grand IEM is a 20awg 4 braid cable and my old Null Audio cable was a hefty 8 braid cable (I forgot the thickness gauge), both are thick in construction so I'm under the impression that you will hear a more dramatic change the thicker and complicated the braids are.
This is probably true for headphones as well but maybe to a lesser degree.

Thicker cables seem to lower resistance which effects impedance on IEMs.

Cables actually effect headphones just as much if not more than iems dueto the ability to being more capable with open back, larger drivers and more spacious housing

So is the internal wires that connect from drivers to removable sockets. This effects headphones more than IEMS for sure

IMO, Dx340 with LPSU can replace a stack of 320/PB5 or D16/PB5 or 340/PB5.

By adding a high quality LPSU, you really think that a 340, stock, with amp 15 card (no Nutubes), will replace the sound profile of a 340/PB5 stack?

Beside the tubeyness, yes. Staging, layering, dynamics, texture fidelity can be outperforming PB5 amp itself

Thanks for your viewpoints.

Obviously, if I had a DX340s/LPSU, I’d compare the sound profiles myself and form my own subjectivity.

One more puzzling question I have for you is concerning the DX340 in super gain mode (12vDC active) while placing the DX340 in Line Out mode.

I think this might have been answered a couple weeks back in this thread, but just want to clear up some points in my mind about it.

Does the DX340 in super gain mode affect its Line Out signal or is it only for its PO signal?

I was trying to understand if super gain mode actually increases the max LO output voltage beyond the specified 2 Vrms for Bal LO, and 1 V rms for single ended LO……or does it add any additional character to the DX340’s Line Out signal.

Chiming in to say that my complaints with battery life are now zero. After a few charging cycles I'm easily getting 8 hours of play in a 24 hour period.

Yesterday morning after listening I kept the 340 powered on but sitting idle for 24 hours. I believe the battery percentage was about 63% when I stopped listening yesterday. I put it in the cabinet with both tidal and UAPP running and Wi-Fi enabled.

When I took it out this morning the DX340 was 58%. Huge improvement.

I listened for about 4 hours this morning streaming from Tidal in high gain.

When I stopped listening the battery was around 18%.

I left it playing to run the battery down to zero and then when I checked again after a couple of hours the battery was still at 11%

I'm definitely satisfied at this point. Huge improvement over last week when I first received it

Yes but you're in the States, I'm in the UK. To be fair that's for a 3M, shorter are less. I'm not likely to ever own one of any length given I'm retired.

And have you done any QFIL flashing, debloating, etc? And how did you install new FW? OTA or manual?
Sorry if I missed that on your previous posts... I am just curious if 0 - 100% - 0 cycles are enough to sort the battery issues
Thanks!

 

[Peekayoh]

Second this although I can't comment on the PB5.
Sorry that was about the LPSU.

I did zero tweaking. Just ran the battery down to zero and charged to 100 3 times

It does effect LO as much as PO. Because LO is a Preamp Out for amp15.

I am not an expert on these, but as I remember reading somewhere, it is possible to measure with a multimeter the line out, while feeding the player with a 50-60Hz sine wave and should be pretty accurate. So, it would be interesting to measure it while AMP15 is also connected to DC in supply to see if there will be more than 2V out from LO this way. Maybe some of the more experienced members here could confirm this.

You can hear the gain effects by yourself. Very obvious, no need for measurements
