ESP Concert Grand SI Loudspeaker seems to be good in today hifi market.i never listened to it but i like to know your idea if you listened to it.I do not like to promote any brand in this forum but i like to know any idea about these speakers.http://...

Gentlemen, working with mathematics as a tool all my adult life I cannot understand your fascination with Goedel's thm here. Yes, it is catchy but I think it does not apply here, it's a rigid math/logic fact, and what's more even leads astray in unde...

I think correct positioning the watt puppy and maxx model in room is not easy and each time i listened to them i sensed a bloated sound, I guessed bloated sound refer to acoustics. i know these model drivers are not fast but i guessed in a good room ...

Romy, I understand you are saying that a midrange horn rated flat to 300HZ should really be crossed at 600 or 1200 HZ. That claim doesn't make sense to me, esp. with a 24 db or higher crossover (active). Unless you are saying that hor...

...and we will start some little Polish mafia here, explaining to the morons the benefits of soaking not only our brains but also the diaphragms of our speakers with premium Zubrowka,Chopin or Zoladkowa Gorzka vodkas ;-)Seriously, nice initiative, ho...

I've got a reasonable offer on this arm.Has anybody tried it, esp. comparing to 3012?Strangely, the arm has already been around for some timebut there is hardly any info around, not to mention good info.Cheers,N-set...

RomyHow about some sort of scaled-up PassLabs F4 or F5 amp ?ie. Class A solid-state with no feedback . You'd get most of the characteristics of valve (tube ) SE in terms of spatiality and low-level info ( esp. in the bass ) but with less of the (daun...

Ok, got it. I second Paul's experience that trying to retrace own footsteps is the best strategy in such cases. Esp. that Dannoys + B3 didn't perform at Bill's place....

I didn't make it to the 2nd video before and it's indeed interesting.Esp. how he describes the result of his trick: "addition of HF transforming into more air and resolution in the MF instead of more glow at the top"(around 2:30 at the video). It's s...

Somewhere earlier last year I searched for some tubes in ex-USSR and YO186 did pop up, esp. in Ucraine IIRC, with not unbearable price ~$100/tube, although in unknown condition (I did not buy any)....

[quote user="Romy the Cat"]London is very fine but the Londoners are even better! I really enjoy to people watching here in London. People behave so different in here and in a way so much freer from thos stupid hung ups that so much oppress unfortuna...

Yes, my question above was not without a reason.Esp. why Mr. Heisig decided to copy&paste his postingon Omnigone from so-much-hated WBF here, 1+year after? ...

Paul, I've been definitely looking at the DIY CNC "market" for ideas!! Esp. regarding the frame construction.The problem is that they are happy once all the frame resonances go to 3-5Hz, so they usea lot of mass loading. Here, my airsprings resonate ...

Actually those fantasies may come true one day...I may be wrong, but I thinkthe tube-speaker interface is more important than sticking to 2 stage topology?2 stage => high-mu output tube => high Rp, low controll over the array.But, if you insist...

Paul, again the diodes are there not because they are diodes and one needs a diode action there, but because they wanted to substitute cathode bias resistor with something that would have a big static resistance (to set the DC point and stabilize) an...

Somehow by my profession I feel I have to do some propaganda at this moment (feel free to remove it).For those seriously interested in a more enlighted and mystical side of science, esp. physicsI recommend reading an old Master David Bohm. He was an ...

Actually I do not have the instability issue sorted out completely...I'm talking about circuit instability now, not the tube instability. Let us imagine all tubes are rock stable.As I see it there are at least two major sources of instability, in the...

[quote user="Romy the Cat"]It is unquestionably an ambiguous project. The topmost question that I would ask myself after this project would be the following: can Milq-biased 6E5P to be as good (sound-wise) DC driver as some vintage direct heated tube...

Hi all,I'm slowly progressing with my assault on the pussyfied 834.I'm looking around for an interesting step up.I've happily eliminated SU-1 (I'd rather daydream about a night withMonica Belluci instead of those ugly steel boxes), said fuck off to S...

Paul, would you think 6336 will be more stable/predictable?Have you had any experience with it?30H: sorry, forgot to mention that the PP pair is autobiasedwith a common 900R resistor...EL34: indeed it's a very popular tube for driving Stax electrosta...

It's dead. Nobody cares about sound anymore. Esp. not about passive listening. The few music lovers left there, are usually immune to their systems, and lack the knowledge to build their own. Most high end audio is a fraud anyway. I agree with Earl c...

IME (i.e. some pm's one dx), the Ex-4 sounds the most civilised -- and this, only up to ~10kHz or 1-2kHz lower.It doesn't sound bad in a tractrix, unlike Paul S' experience with a dx4.A horn is also useful to provide some extra spl (106 spl at 1+m wi...

Hi Paul,Completely agreed - I clumsily said plugs, when I meant spades - was simultaneously looking at some proper lemo plugs for signal and got confused.... Bananas, esp. for big hog woofers are - well - exactly that.I've also used the technique you...
|

I know, it makes sense to think about me in such a way because of not knowing more about me, but I definately have potential to get to good places in audio if I just had some things improved here and there... I have belief in my capability even ...

Hi Guy,Thanks very much for providing me your insights on the SP10.I have to confess when I initially read your comments I could not help but be astounded that a person involved with a Brit belt driven, light weight, suspended turntable would be usin...

Romy says:[quote]The problem is that in context of those amplifiers the COST BECOMES THE MAJOR DESIGN IMPEDIMENT[/quote]Yes, but it shouldn't -- should it?Let's be reasonable (a tall order). Either a designer knows how to design or not. If he doesn;t...

One thing to bear in mind with the bass horn delay - I thank Tom Danley for explaining all this a while ago - if I understand it right, a small direct radiator (ie small in relation to the wavelength - which will obviously be the case with ...

AlloWell, I hope I wasn't threadjacking too much; as far as I see it, the best case for digital processors is for messing around with the time domain, not for x/o'g. Ah, so you feel a bit of phase shift at LF is beneficial... interesting. I've a...

Hyeronimus and his lysergic masterpiece has been an obsession for generations... I remember and still have in some ESP Disk issues by Pearl Before Swine's, Sun Ra's, Tuli Kupferberg's a beautiful, foldable, high quality repro of the HB's Tryptic whic...
