I think Clark Johnson while he was doing his typical promoting of potions that would make hairs to grow on CDs was once pitching some kind of sheets with excellent EMI/RMF shielding. It is possible that EMI/RMF become a subject only when two or more ...

The HD Radio for a first time in my own room. Hm…. I do not know what to say. I was listening my “far and ugly” WCRB station and it was “cleaner” in term of noise but it was very different sound. Something is not right with HD Radio and I canno...

The Lavry DA-924 and Sansui TU-X1 are on separate equipment legs/chains and only come together at inputs to the amplifier. They also are on separate uninterruptible power supplies that are on separate legs of our wall supplies. Also,...

Which are huge, they not even sound as the same orchestra into the same venue. I don't know if my computer rig, which I must use to play the 24/88 files, using a pair of SL600 into a very small room, would qualify themselves as a whole injection chan...

I have been looking in to mid bass horn designs to experiment with lately for the 4 way horn pa I am working on. As usual Good Sound Club always is on the Google search when dealing with any kind of horns. Although my reply to your post may be a few...

Considering the employments I would like to make in my installation after the floor will be done and the system is re-assembled I am very much thinking about some kind of new cable management solution. I have 21 powered components in my playback syst...

[quote user="Paul S"]Is the "ground plane" in this case literally a sheet of copper that you run all the grounds to? If so, this may be overkill on the one hand and an antenna/noise magnet/generator on the other hand, and/or it may well make for grou...

[quote user="N-set"]... I cannot imagine where the fuck I should have a loop??? [/quote] And you are not alone. Any single person who is chasing noise in phonostage ask himself the same question. I assure you that sun of later you will find it and it...

N-Set, why would you disconnect from the house neutral, unless you are using battery power??? This "neutral" is the "ground" leg of your circuit! The house neutral wire is typically white, and the house ground wire is typically green. The "extra", g...

[quote user="jessie.dazzle"]These might spark an idea (cable insulation must be of a quality that will remain flexible over time):http://www.countryliving.com/cm/countryliving/images/Kitchen11_Lamp_LowRes-de-37581708.jpghttp://media.restorationhardwa...

Like I said in several tuner/antenna threads here, I have never had good classical FM/programming to tune in to, anywhere I've ever lived. And my travels suggest that your good times in Boston were an exception, versus the usual fare in other metrop...

Thanks for your responses guys. Would be great to learn some practical procedures how to setup a tuner/antenna combo properly.
Any ideas where to find some sort of a tutorial? For example I'd love to learn what are the tuning scope images in t...

A correction or two:
The WHRB transmitter is not at their studios, rather atop One Financial Center downtown, across from South Station. The antenna height is 186m. For you it's nearly in line with WGBH.Clark the miserable repor...

This weekend I decide to take my FM where it should be. I ran ~125” and installed a dipole on the roof of my building and serviced my tuner. The result was as expected but there was something unexpected. Along with all normal benefits of better anten...

[quote user="Romy the Cat"]You would not need any “special” A/D converters, as I did impose any demeaned to “quality”. All you that you need to have a more or less reasonable tuner, a good antenna, strong reception and an ability to write it up at 24...

Here we go. One more person got hooked on FM and “get” where the real high-end lives… If you live in Chicago then try to develop some connections and get assess to folks who have WFMT-FM sound-check tapes form the WFMT’ past. 20-35 years ago WFMT-FM ...

The Rohde & Schwarz EU-6201 tuner was made for German Ultrakurzwellen (ultra short waves or FM) Broadcast Network. The idea was to have a chain of wide-bandwidth composite signal receivers that feed re-transmitters. I made an attempt to accommoda...

All transformers are phase inverting. The lowest leakage point of primary and secondary windings relationship to conventional E/I and C core is the physical start of the helical spiral winding. This is assuming more than one layer of wire. In toroid'...

It's hard to give prescriptions for ground problems, since they may be both myriad and complex. I can offer that my own current system performs best with all 3rd wire grounds disconnected from the wall socket at the component. For all I know, this ...

So, what you would have to do is buy a bunch of #9 AWG solid copper wire from China, so it is only 99% pure,acid etch the surface, paint it with tar and wind it up in a snake sex twist. Or pay them to do it for you.The idea is sound, the application ...

Well, I have to admit that the stupendous sensitivity that Sansui TU-1X have after the Stereo Surgeons tune up to use the TU-1X is kind of complicated. With 0.8mkV this tuner picks the noise that my DACs radiate. I staffed all wholes of the Sansui’s ...

[quote user="jessie.dazzle"] I live where FM program quality justifies a good tuner. Despite getting what I consider to be really excellent sound from this modded TU9900, I will one day compare it to a TU-X1. I will post my findings here.[/quote]

Today is the last day of BSO season and the first day what my antenna is up and I might listen the BSO in it’s full glory. The azohen-vey Glory! I was listening the programs today before the live broadcast. It is not that I do not like the sound. The...
