From an audio expert....Normal RCA cables are crap because they don't block radio frequency interference. All you have to do is replace them with SPDIF (AKA video RCA) cables. They are only slightly more expensive than regular RCA's. But are much better than even the most expensive RCAs you can buy. Its all about the shielding......

I replaced my tonearm wire with Cardas litz wire and also had it internally dampened. I added a new KAB PCB with Cardas cable hardwired to it, and it sounds phenomenal. I’ve done a lot of the KAB mods and upgrades too, but I’m an audiophile, not a DJ. KAB has tons of parts for 1200’s, and I’m sure DJ’s order stuff from Kevin at KAB too. Great vid, man. That must’ve taken a long time to record and especially edit. Bravo, sir!

One of the main reasons the high end on a Technics 1200 sounds muffled is if the VTA is too low. If the azimuth of the stylus is too low, the sound will be muffled. If the azimuth is too high, the cart will react too much to the high frequency part of the groove and the bass will be weak. The best way to perform this test is to use a single tonearm and stylus and only change the cables. That will eliminate differences in the VTA (azimuth) adjustment of one tonearm Vs the other and the height of different platter mats, which also affects VTA. Otherwise, you have too many variables. Edit: Ah! I spoke too soon. I see you did this test later in the video. Nice work!

What a nice test setup. Well done by changing only one parameter (the cable) at a time. It would be interesting to know what curve the producer of the test record actually recorded. Keep in mind that the signal before the pre amp has the RIAA curve built in. Nice to see that many cables give similar results. I'm not throwing out my cheap rca cables for now!

You should've measured the capacitance of all those cables. It's probably the cable capacitance that adds to the load capacitance of your cartridge. Most of the resonance effects of load capacitance is between 10 and 18kHz.
@Eric-uf8zx5 жыл бұрын
I think the Van Damme cable is rolling off the top of the frequency response, whereas the other cables are producing a flatter response. Phono cartridges will change their response if there is a lot of capacitance or resistance in the cable. I believe some of the Van Damme cables are very high resistance carbon types, just like some car ignition cables, this might be the case here, but you'd have to measure the cables to find resistance and capacitance, you can do that with a multimeter capable of measuring pF capacitance, just measure between the rca center to outer connections at one end without the cable attached to anything, make sure your meter is zeroed as most meters have some residual capacitance in the pF range also make sure you are not touching any of the conductive parts while you are doing the measurement as it can give you a false reading.
@DJlegionuk4 жыл бұрын
After this I found a few more Van Damme upgraded cables and I tested the resistance and capacitance with a LCR meter. None of them are high when compared to any other infact they are lower, but at the time I did not think to make sure they are all the same length. I am just happy that it was only the original cable on the customers deck that has this problem, but I still can't say why.
@Wised1000 Жыл бұрын
Worse than that, the Van Damme cable is not only attenuating the signal it has uneven response at the higher frequencies. I have never seen a cable that bad. Maybe it is damaged in some way. Bad soddering or something else.

I'm curious to try this. I think I'm going to. I've been wanting to get a test record for preamp and playback related reasons but the used MK2 I just bought has some aftermarket 1/4 cables jacked into the underside of the deck. As in 1/4 to RCA with the 1/4 inch on the turntable side. Idk if they're balanced 1/4" or not. Weird, never seen that before on a Technics. Maybe it's better, maybe it isn't. I have no idea. Test, fix if needed and move on to the next oddity I guess. I suppose you just chalk that up to the joys of buying an old Technics these days. Will report back after I open up the deck and test it. I saw someone mention needing to use balanced cables for the cable swap to work right. Idk if that's how mine are yet. We'll see I guess.

Except for the Van Damme cable the rest appear to have roughly the same impedance per foot or per meter and don't attenuate the higher frequencies as badly as the VD cable....You can just cut a foot, or a meter and measure the capacitance with a meter that will read down to 15pF or so because most cables will be round 18-20pF per foot or about 70pF or so per meter....Make sure you separate the conductors at each end if you do decide to test the capacitance of the cable.... I'd say the you either got some cable from a bad production batch, or that cable was poorly designed....

I've got an old turntable from Technics model SL-B202 on which I want to replace the old original RCA cable whose leads are directly soldered to the terminals inside the unit as well. To this end, I bought high-end brand new QED RCA cables ; so far so good, but problem when I cut both cables I noticed that are not two (as 'traditionally') but three separate wires in each cable sheath. Any idea how can I connect i.e. solder these 6 wires to the four-terminal circuit board of the turntable ? Many thanks in advance, Cheers from France

A cable can't boost a signal. The hump must be coming from the cartridge or the phono pre-amp (or the record itself might not be as accurate as it purports to be!). So, DEFINITELY there's no "benefit" from what you're calling a flat response on the Van Damme cables...they're just very poor at higher frequencies than all the other cables.

I only have a few stylus and it would mean buying them and I earn next to nothing from these videos. like £90 in the last year !!!! so it would be hard for me to compare stylus unless I have them and I am sure it would be open to criticism at every step. As for tone arm repairs all I can do it replace the bearings on the centre pivot with small BZ 5mm style from RC car shop. I am getting better, but it's still like 50% failure and I have to try again. The silver tubes are special enough that no one we have asked in the uk would make them unless it's in the thousands so we are left with trying to buy bulk from china. Calibration is just getting it to move freely across the record without that top lock screw being too tight or loose that it has a bit of wobble. I remove the silver tubes and check with a flat surface for any gaps or twists. Thank you for subbing and watching my vids, it really appreciate it.

The Van Damme cable is pure trash, its acting as a filter. The other cables are showing the correct slope. They are flat (more or less) till they reach the higher frequencies (where its not the cables' fault but rather the natural frequency limitation of the stylus) where they roll off gradually. That's why you see a frequency response spec they also provide you a range of tolerance AKA +/- db.
