[quote user="Antonio J."]So I thought my tuner weren't properly adjusted. It has not been serviced nor recently aligned, I have no proficient technicians around who I depend to let them put their hands into the tuner. The damn thing always ...

[quote user="Romy the Cat"]Hm, this is interesting. I my case nether neither CEC nor Bidat affect other of the tuners. Lavrys do but not Bidat. Try to put ferrite on ALL Sansui inputs: antenna, power cord, output cables. I have 3 bids on each leg of ...

[quote user="CO"] May i ask if you have ever played with the Le Cleach flares and how you find them?They were created to reduce reflections directly back into the horn. Only problem is they are very large because of this.... [/quote]
Nope. I never h...

Klaus,
The 515-8GPH were in same scale as the 515G with slightly above 35Hz resonance frequency and 103 sensitivity - a very good candidate for 60Hz horn. The 10” throat? No bolls to go for 9”, how about 8”? I’m just kidding. The throat ...

[quote user="Romy the Cat"]OK, everything was fine and I might do into the sonic nuances of the PurePower unit. The PurePower drives a lot of switching nose from output. It has the filters but they help only partially. Adding capacitance to the PureP...

Thanks, the high nominals the have only 630V and they are larger than I would like to have. Does anyone know how those Obbligato sound in PS?

I presume that whoever read this thread have gone over my comments about the Sound of the former PurePower 1050, particulary my comments about the PurePower’s “Super Texture” at the page #5 of this thread. This controversial “Super Texture” was my ma...

A clue!You are not using the ground on the PP3000 unit and have ferrite packages on the incoming mains supply.I am guessing that you have fitted a clamp directly around the power cord.If this is the case, then you are using the ferrite on the ground ...
|
|
Romy and ClarkeA couple of tips here:To be truly effective, you need at least 3 turns of L+N through the ferrite; more if you can.The "Y" network can be placed either side depending upon where the PP3000 to PP3000 interference is coming from.You may ...

Yes, thanks Charles and thanks for everyone who sent the direct amps on this subject.
The ClarityCaps, similar to the Canadian Solens, British Ansars Supersound, the French MKP, and a few others proposed, are all Metallized Polypropylene caps. I am ...

Paul,It would be improper for me to write down what I have worked on over almost 40 years in the telcoms business. WRT a CV for example, I have in the past written it all down and the reviewers do not believe it. Eventually, i stopped bothering abo...

Decoud, this is certainly the evolutionary idea, all right, that I have been turning over in my head for a while now. However, even to start with, if nothing else, there is with FC the opportunity to "dial in" flux by ear.I cannot remember when, but...
|

John, thank you very
much. You did point out the area when I did not explored deep enough and I will
certainly will experiment with it. I need to educate myself about ferrite types
and about proper ways to form the ferrite coils. Up to now I used ...

So what is with the ferrite beads? Do you find they are necessary? Seems to me the resistors right on the socket would be good enough. Especially with the grounding of the center pins. I run beads all the time in my digital si...

After dealing with my tuner pick digital noise from my AD and DA, and particularly from Lavry DAC, I loaded Lavry with quite substantial amount of ferrite anti-RF filters:

Continuing to harass the readers of my site and myself with the good news about the performance of my SA8535 driver I would like to post a very educational article about the subject. As I told before, being familiar with sound of ribbons then never i...

I have not experienced any ill effects from ferrite beads myself. That is why I asked. Some report sonic degradation issues (like CH at Ayre). Some say they can get magnetized. Listening to the masses I am unable to put togeth...

You do not have other ways to connect then how you have connected as in your case of M-Audio card you have AD and DA abort to you DAW. I would load with ferrite in common and deferential mode the cables that go to tuner and play with the way how you ...

The electrolytic capacitors in the woofer low pass circuit are certainly dead. They look perfectly normal when old, just lose capacity in a serious way. The NS1000 had ferrite magnets that don't need remagnetization....

Somebody from AA was asking about electromagnet. The subject pup up here from time to time but this time Bruce Edgar uploaded an interesting comment. Bruce is not a typical AA Moron and if he says “inaccurate things” then it is not due to ignoran...

[quote user="Romy the Cat"] Still the key is to treat the cables, all cables that go into tuner and into the processors. Do not forget that you have a perfect loop: tuner goes to preamp, as in the same time tuner goes to A/D-DAW-D/A- preamp. So, you...

Yeah, "sound consistent independent of signal level" is a very precise way to sum up my whole speaker philosophy. Anything that is assumed to be constant, but which actually changes with signal dynamics is what ...

[quote user="jp"]In my experimentations, the da924 doesnt contribute much noise in my setup. Rather in my setup its the lavry ad122 thats the trouble maker. When all digital is turned off I have a very quiet background. Here are my observations...

On the sansui, I tried using ferrite on all the rear inputs. No change in noise level.
On the ad122, I wrapped a single large donut around the interconnects,
which are supposedly shielded, but no change in noise level. I tried
putting ferrite ...
