I do not use drugs in any form, as I possess all necessary crassness within myself without using any external incentives. Saying that I would much rather to see our government supply citizens with LSD then with Iraq’s death certificates. At any...

I note English Mfgrs tried low power ribbon Midrange horns in the 50's (Decca, Kelly & Quad also made one!).These were probably inspired by the hi pwr prewar? Klangfilm ribbon horn (would like to hear one of those!) But, after Peter Walker moved ...

Dear Romy,I performed the following tests:Test 1.Digital CD source OFF;Digital Domain DD-2 processor OFF;Lavry DA-924 OFF;Sansui TU-X1 ON and set to FM output;Custom tube amplifier ON volume HIGH;ESL-57 speaker arrays ON;Result: no interference and n...

Interestng, I did not near horn load Electrostats. What the profile and what the mouth rate of your horn? What the resonant frequency of Electrostats you have before and after loading? Are you driving the Electrostats direct from plate or via a trans...

I use Jecklin Float Electrostatic headphones (known to some as ear speakers as they sit slighlty away from your ears) and the nearest speaker I have ever heard emulate the feeling of these headphones is the ESL 57's. They are noto...

Romy, cats, dogs, i drugie zverione of my first posts here...May I suggest one mechanism, speaking out of pure theory here:the ansars have alledgedly much smaller esl+esr than mastodont electrolytics.This creates higher Q tanks, also higher tuned. Th...

Hagtech, why not??? VR's are sensitive to parallel cap, as they have intrinsic esl (few mH). choke will increase the ac regulation.Of course it must have enough DCR (or R in series) to give the static voltage drop (giving e.g. some trace of line regu...

...if you wish. even with Mex flavour ;-) I'm sorry I was imprecise. I ment exactly what you said...and forgout about 3200Hz...but I think that there is something more interesting going on here: what you have hereis rather a rare instance of an intel...

Ah electrostats...I am fairly sure that problem with esls is trying to take them down to low and them not being driven properly. If you actually calculate how much current you need to drive transient peaks into an ESL, it's horrifying. I can't imagin...

Dear Roman and all... also unrequested/unsolicited, MUST give my opinion on the above... I had to translate my 2,3 meters from my Gotorama speakers system, and obtained 7,6 or so feet... it's angled 110° in front of my head, placed on 5,3 meters long...

Forgot to elaborate the Quad system.It is actually a tri-amp Quad system, below 100Hz is the Supravox 15in Field coil in open baffle, then it's a Stacked Quad ,and about 5Khz there were 5 RTR ESL cell. I did try the 6C33C amp in a single pair Quad by...

Nice posts Romy and Jan, agree almost 100%. I've heard the Behringer in an originally crummy system and it butchered things completely. The input levels were low, which as you point out, won't have helped at all.On a vaguely related note: I dunno if ...

HelloI've always wanted to try an ESL as a horn driver:So I employed a hi power Koss 3-layer bass module cut from Koss "model 2" spkr.Polarizing voltage was low on Koss design so it was upped to 3kv w/ custom PS.Horn is old closet that had a trapdoor...

I twice had the opportunity to listen to a Wilson: The Puppy 8 combined with a Lamm power amp and the latest Maxx with Soulution electronics. Both times my impression was that there is some characteristic shining or radiance probably induced by the b...

Maybe if you didn't try to pull the caps down so fast. Why the hurry? Maybe a 500 ohm or 5k ohm resistor would be a more kind bleeder. I think the peak current spike is not such a good thing for the capacitor. You are also at ...

Hi Romy,Do you find listening to music at home through the old hifi system more enjoyablewithout the need to become intoxicated by our government drugs or do you haveto remain bolt upright like a Sgt.& totally in control of your body.Never t...

The preamp has the classic tube regulated power supply using 5R4, 6AS7, 6SJ7. It is transformer coupled output and has no capacitor in the signal chain, the gain is about 8db, so it is not a buffer. For convenience, it does has a remote control. It i...

[quote user="Romy the Cat"]Arno, I am glad that you take my comment with right attitude; this is indication that you are not dead, despite the fact that you are building a back-loaded horn. I do not think that you find a lot of useful horns informat...

just been this feb in NY city to an exclusive Wilson studio. I thought that the rushy noisy exhibitions where their portfolio sounded very average to me was maybe not fair to judge, if everyone loves them so much. So in that studio i got all the time...

[quote user="KOTriode"] Without regulation, this amp would not work correctly due to its design: DC coupled and fixed bias. The high transconductance will make the bias current varied as much as 50-100ma due power line fluctuation without the reg...

Yes, I've heard this theory too that paralelling caps lowers the esr/esl => better rise time.No idea if it's true or only an excuse for not using big, hard to get and expensive single caps.PSA quote from arandom physicsforums thread:"In the genera...

Hi,[quote user="Romy the Cat"]T, would you elaborate on it if you feel that it has any merit?[/quote]Really, I do not know. From my limited experience I have found that multiway active systems are very much a tuning excercise par excellance. Given th...

Hi Romy,Probably my evaluation methods are still quite moronic, but I think I'm learning to listen to what matters in the music. I had some experiences with a friend using several caps in a preamp he built, and also in the integrated I'm using. I und...

Hi,[quote user="morricab"]Thanks for the info about transformers. It is as I expected, however, that these passive devices are not passive sonically at all. I agree with you that the higher quality of the transformers should lessen the effects ...

KOTriode. One of the reasons why I advance the idea of using 6C33C for sub 100Hz bass is because it is very easy to say objectively if it is enough power. You see, when you use 845 for instance the tube might jumps in and out if A2. Since it is D...
