Where do you source your expandable sleeving? t is a German company and is called ViaBlue. It is a subsidiary of the "Summer Cables". These are worldwide equipment suppliers for studio and stage technology acoustics https://viablue.de/de/index.php 😎 MicroMara Quote Link to comment Share on other sites More sharing options...
glens Posted January 18, 2020 Share Posted January 18, 2020 While the cables look really nice, and I'm sure they also conduct electricity at least as well as needed, I'm still stuck on the use of the contact product on the drivers and crossover. How so and why? And what was the result, specifically? 1 Quote Link to comment Share on other sites More sharing options...

In phase 2 of the project, the original insulation material was exchanged for one of the insulation materials currently available, which binds air and structure-borne noise. As a result, the crossover built into the rear of the housing is less of a structure-borne noise than the mid-low woofer. The chassis have more interior volume, the damping factor of the new material has made the inner housing "dust". I would almost like to describe the positive acoustic effects as "dramatic".

MicroMara Posted January 18, 2020 Author Share Posted January 18, 2020 I thank you very much for your appreciation for the cables. I get the raw material from one of the leading manufacturers of industrial cables. The specialty of the loudspeaker cables and jumpers is that they all have a copper cable cross section of 12mm2 per phase, including the jumpers. Therefore my MK II is fired with a total of 4 x 12mm2 = 48 mm2. These speaker cables have no inherent sound but only transpose "energy" due to their cross-sections 😎 MicroMara 1 Quote Link to comment Share on other sites More sharing options...

How so and why? And what was the result, specifically? The "Contact Enhancer" linked by me is used as follows. As a stopper on the bottle there is a small swab in the liquid line at the end of the stopper. All Cichkabel / XLR cables are wetted on the plugs and sockets, both inside and outside. The same is done with his electronics ... on all Chinch / XLR / Digital / KoAx / Terminla pole terminals on the speaker, the contacts of the speaker cables, i.e. bananas, spades, angled banana plugs, etc. Also the cold device sockets to network players, CDP / AMP / Phono / so everywhere. Then reassemble the system 😂 I do not give a sound rating, nor a guarantee that everyone will hear / perceive in his chain ... so I would like to know if someone of you tried it out, what happens there or not .....

MicroMara Posted January 18, 2020 Author Share Posted January 18, 2020 In this example you can see on the lower copper coil in the switch how it looks, at least visually, once before and once after wetting the contact fluid Quote Link to comment Share on other sites More sharing options...
glens Posted January 18, 2020 Share Posted January 18, 2020 That's what I thought you'd said. The coils could be painted or have anything non-magnetic smeared all over them and function the same. You are aware of this? Quote Link to comment Share on other sites More sharing options...

However, current only flows on the surfaces of a coil. You would have to measure how and whether the current flow from an untreated to a treated coil changes. However, my focus is now to deal intensively with the new external crossover for the Rf7 MK II. The new, wider and deeper housings are already in the works, I think they will be completed in a good 14 days. 1 Quote Link to comment Share on other sites More sharing options...
MicroMara Posted January 19, 2020 Author Share Posted January 19, 2020 My cables for loudspeakers are not only made for classic stereo as 12 x 12 mm2 single> single wire, but also as single> bi wire versions of 2 x 12 mm2> 4 x 6mm2 . So I can also go with my cables over long distances up to 20 m, with almost lossless transmission. therefore my cables are also ideal for use with 5.1 > 13.2 surround systems .

MicroMara Posted January 19, 2020 Author Share Posted January 19, 2020 One last piece of information about the Contact Enhancer Before: Is between the two contact surfaces Dirt and oxide layer embedded, there is only a few direct contact points...... After : The contact agent has removed the dirt and the missing parts with atoms refilled. Over the whole contact area is now a positive connection is established. The improvement in contact quality is considerable. 1 Quote Link to comment Share on other sites More sharing options...

You would have to measure how and whether the current flow from an untreated to a treated coil changes. Only on the surface at frequencies much higher than direct audio. If you have altered in any way the way current flows in that single wire wound into a coil I can practically guaranty you've altered the value of the inductor. In each case. I'll let you continue with your further wire / house-wiring-as-networking developments unhindered... 1 Quote Link to comment Share on other sites More sharing options...
MicroMara Posted January 19, 2020 Author Share Posted January 19, 2020 Once again a really very last statement regarding "Contact Enhancement"...... Conditioning the contact surfaces with "CT" minimizes the contact resistance on all types of connectors (XLR / RCA / loudspeaker / digital etc.). The result - your hi-fi / high-end system plays to the point - precise, open, with a stage. "CT" achieves a significantly higher performance. And this with every system. Mostly, hi-fi and high-end combinations transmit signals less than 0.000001 volts. So incredibly small signals. A good MC phonotone cell e.g. produces maximum 0.4 mV. Assuming a dynamic range of 60dB, the smallest signal is less than 1 trillionth of a volt. Even with normal XLR or RCA connections, the smallest signal components are in the pico-volt range, i.e. at 10-12 or 0,000,000,000,001 volts. The decisive factor in the transmission of LF signals is that it is the last percent that really interests us. Because this last percent contains the sonically interesting details such as spatiality, fine coloring, fine dynamics. If these details are not transmitted, we will hear music. What touches, goosebumps, airiness, sense of space, grip is not felt. Best regards MicroMara 1 Quote Link to comment Share on other sites More sharing options...

Forgot for a minute you are not in Great Britain. Just a title of a OO7 Film...book, for your eyes only. Nothing derogatory intended, I can assure you. A bit frivolous at times, maybe. Nothing to apologise for. On the contrary, still rather enjoying the progress of your presentation here. Thanks for asking. 1 Quote Link to comment Share on other sites More sharing options...
