Stands for Super Melquiades.

Those all things take too much space and the new amp for the “fundamental channel” does not really help the situation. I decided to convert the Super Melquiades into something that would have smaller footprint and position the control amplifier unit atop of the power supply.  The power supply is vibration noisy (12 pleases of magnetics inside with the stupidly steel chasses) and the control amps are vibration and noise free. I need something that would decouple the noise and position the amp vertically. I thinking something like on the image below but I would need a time to figure out what materials and decouple techniques actually work…

Supper Melquiades sandwidge...

Ah, last night, after midnight I picked in McMaster-Carr some elements for my proposed Supper Melq rack. Thy shipped it UPS ground and I had it delivered that same day! How they do it? Anyhow, I connected two shelves with 4 x 12” by 5/8” rods. I tighten it very strongly and it turns out to be very firm, very simple by quite effective rack. Actually the Super Melq on the rock become twice smaller and become very-very comfortable to deal with. However, what I was concerned if I were able to associate the mechanical noise form the power supply that sits at the bottom shelf from the top shelve with the control amplifier.

I do not do crassness listening equipment with the different isolation devises. Yes, isolation, suspension and targeted pressure applying devises do work in different ways and I experimented with them a lot in my past but in this particular case I did not care “how it sound”. All that I cared this time was the propagation of hum from PS to amplifier.

So, I put the power supply and the amp on the shelves, turned them on, armed myself with stethoscope and begin to listen. I have to mention that over the years I stupidly accumulated in my closet a load of all imaginable cones, isolators, suspenders, rolling-block, vertical bearings, decouples, creasy custom feet, some of them super high-tech with many hundreds dollars price tag. How it was time to put all this crap into work….

Without anything the bottom and top “sound” (via stethoscope heavily pressed) practically identical with the same volume. In my case PS sit on it rubber feet but I was not able to find anything of small height that would decouple it from its shelf. None of the custom feet, cones or “sliders” were effective, in fact absolutely ineffective. The mild success I got putting the PS atop of the 1.5” sorbothane sheet. It reduced the amplitude that was delved to the bottom shelf and lower frequency. Still for such a large layer of ultra low-density sorbothane I felt the effect was not worthy. So, I figured that the problem is the very high mass of the PS and I decided to let it be.  Therefore to left the PS to live right on it’s shelf and concentrated on decoupling the control amplifier form it’s second self.

Once again, not of the audiophile tricks work effectively including the large Symposium platform. The double think (3”) sorbothane did work the best but the mild noise was still auditable via stethoscope. Eventually I put atop my rock the Silent Running Audio platform. It was like magic! The control amp sitting on the SRA platform was absolutely silent. I have no idea how Kevin did it bit his platform absolutely objectively works. I can spread foolishness about sound quality with and without this platform but honestly I did not listen it. All that I was conserved to make the PS does not affect the control unit.

In the end, I am very pleased with the new Supper Melquiades sandwidge. It saved a lot of space and fits perfectly in my corners. Now I have some space fo something else… and I know it will be coming…

RE: talking about the audio mystery…

I set up both Super Milqs on their new stands and they look very-very cute in comfy in their corners. They also srayhigher and I can reach the plate current regulators without bending my body. Since I become “circumferentially challenged” lately, the ability to manage my playback without bending is become more and more valuable… :-)

Anyhow, here is the mystery… The system completely got misbalanced imagining-vise. It sounds like each driver time-misaligned and the sounds are flying like wounded in ass gazelles all over the room. It actually even funny to listen like this as I would not know how to do it intentionally…. I can only presume that it is due to the heavily disturbed Dominus cables and I pray that it should cure itself after a few days…

Has this situation changed at all?  Has it been remedied?  Did you ever get to the bottom of it?

Nope, unfortunately it did not. It kind of creating problems not as I am about to plug in the new “fundamental channel”

and I hardly know how I might interpret the result. Something went wrong when I lifted the amps from floor. I would need more time to figure out what it going on….

Rgs,

The floating transforms & chokes in PS?
Interesting, I had a prolong conversation last night with Kevin Tellekamp of the Silent Running Audio and we discussed my case. He proposed that the reason why my imaging was changed was due to the Super Melq’s powers supply in my nest stand do not sit on flooding platform anymore. It does sound like a very crazy proposal as there is nothing in PS besides the transformers, SS rectifiers and the first LC chain of the filters but it is very much might be as it would be it.

Did anyone have seen that “comforting” the transformer and chooks of a separate chassis might affect the imaging of audio component?

Wavac Audio Lab 805MK-II
fiogf49gjkf0d

Wavac Audio Lab announced a new amplifier: MD-805MK-II.

http://www.wavac-audio.jp/md805mk2_e.shtml

The amp uses the same idea that I pitched with my “Stands for Super Melquiades” idea – 2 floors with small footprint. The way how Wavac organized MD-805 is wonderful – 4 vertical pools with a suspended between them PS (look like) and the pools are caring the control amp. If it was me then I would put a special anti-vibration platform between the amp and PS, I hope the length of the power cords on the back would permit it. Otherwise, the way how the Wavac MD-805 is configured (with exception of color) I find is examplarery.
