Suddenly i got a hint of connecting my powered desktop T40 speakers to my soundblaster z card headphone out with amp. Sound/audio play improve a big amount compare to the usual 2v line level output. What come to my mind is that 2v is very small voltage which can only drive 1m length of line level cable. Longer than that, quality and performance will drop. While trying out different length/size of 3.5mm line level cables at the headphone out with amp, i found out that even a reduce in size and length from a thick and 2m length cable make improvement to sound/audio. A search on the internet also can find headphone amps that enable connection to both headphone and powered speakers. Anyone has opinions on this and using headphone amp for powered speakers can kindly share it here.
Electricity is the science about the quality of contacts. I would believe in 2m vs 20m difference, but not in 2m vs 4m... I remember having several cables (of the same length) but only one of them not having some static noises - either due to proper soldering of insulating braid or something else...
2V RMS is RCA Standard, 1V RMS is PC Standard (why I have no idea) and Creative typically adheres to 1V RMS unless specified in specs. Using the headphone port on the soundcard is amping the output, which is probably making it louder, which humans perceive as "better". Until it clips. Want a good quality 3.5mm interconnect that isn't expensive? https://www.amazon.com/Monoprice-105583-50-Feet-Premium-Stereo/dp/B001T21DU4/ref=sr_1_1
Since the world we live in is a dream world (world of matrix), don't get trick, 1m is the optimal length for line level if audio/sound equipments only output 2vrms of charges. Anything longer is consider a working length, not an listerning length There are peoples claim to get better result from 0.5m length. If you look at my system setup, there should not have fuse at power plug in order for it to function truly. And i put ferrite magnet to suppress rf/emi. My soundblaster z line level output is 2vrms. What i am doing is like putting a pre-amp before the power amp, it not uncommon, it greatly improve audio/sound performance. You recommendation of 3.5mm interconnect is at the right time. I assume god know i happen to be searching for it and already placed order, thank you.
if you have the time (and 3M "command" clips) running all power lines 10cm parallel then crossing at 90 deg angles will also improve the sound by deepening the sound stage. i borrowed a trick from the old hi fi cabinets and made a false back out of spray painted masonite where i made the wiring harness on the back. but that is for a DAW which is why i recommend the damage free wall clips from 3M as you'd be done in a fraction of the time
Unless your hearing a noticeable problem, it's not a problem. Same with ferrite beads. Unless you are hearing some hiss or problems with the audio before putting them on, they aren't magically making the audio better by just being there. But I'd have to assume you had a problem, that's why you did it and why your considering cable lengths. Because v1, or v2, 3.5mm can work at lengths WAY beyond 1-2m and not have an issue.
@teots SB Z spec: Front Channel Out: 2Vrms Headphone (33 ohms): 1.3Vrms Headphone (600 ohms): 2Vrms So you have a sliding voltage output based on external resistance, but the amperage is low: 300ohm headphone out: 22 mW, at 33ohm : 46 mW Also, thicker cabling lowers resistance and allows for a longer run on analog interconnects. This whole 2v RMS with 1m (3ft) limit is unfounded. This is why you can run speaker wire at longer distance if you use a thick enough cable.
There is no need in "believe" in world of audio. You can record same audio cut using different cables and then you can compare records. If you claim there is difference then you will see difference in comparison. PS And there is blind test approach...
If you know the resistance in Ohms per meter of the cable, you just calculate the voltage drop over whatever the length of the cable is. Read up on "Ohm's Law." It's not that complicated.
true, but you forgot capacitance and resistance. and btw... capacitors and resistors are used to make an (analog) eq

Ok folks,my new cables finally arrive today. A monster mobile audio 3.5mm 1.2m and the other is Monoprice 22awg 3.5mm 1m cables recommended by @Chastity (Thanks ). The third one which i already had is Qed connect 3.5mm 1.5m cable. This 3 cables are mild sounding when using line level out on my creative soundblaster z and T40. It's only good for music listering at best with the 1m length cable. When i plugged them into my soundblaster z headphone amp. My speaker come to live with high playback capability. The best game/music playback result is still the monoprice 1m cable. High playback capability, faithful reproduction with nice and accurate tone and vocal even at 30 feets away from my speakers. My audio/sound setup is finalize.
Nice, glad you hit a configuration that you like the sound of. As honestly we can all go back and forth on the technically details, but if this doesn't break anything and you like it how sounds your kinda good to roll.
A bit of discovery when looking at my soundblaster z control panel. Image 1 show that show headphone when speakers were plugged in. Image 2 show the playback device as speaker with adjustable volume. Therefore my soundblaster z does support headphone amp to powered speakers, of course not all soundcard/on board sound chip are able to.
Update: my first audio music play session with such setup. Format is 16.bit 44.1khz wav, the artist is Cai Xin Juan.
