[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...

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"] I do not know if “stupid, indiscriminative mass loading is a road to nowhere”. [/quote]Let me try to explain why I think so. Adding mass (e.g. sand+shot loading of steel profiles):1) makes the vibration amplitude smaller f...

Paul, as you write the pendulum effect is unfortnately unavoidable if one wants the levelingfreedome of spikes, so I try to live with that. I looked at Walker...tjaa....$1750 for a record clamp...I also saw how he works on his suspension (look at my ...
|
Paul, thanks! I'm quite happy to hear I'm not the only one fighting vibrations in a seemingly dead structures...It takes a lot of thinking to properly isolate and damp vibrations.Not unlike in the complementary problem: reproduction of the audio rang...

Thanks de Charlus. Indeed countless hours with CAD soft and redoing the thing didproduce a nice visual effect (my pic is quite shitty and deformed...sorry).How it will behave? Time will show. Listening to audio racks is one of the last thingson eart...

So here is the promissed picture of yet unfinished rack:It's huge (the columns are 10x10cm) but still quite elegant-looking in my room. The electronics rack on the rightwill be put inside the TT rack when I finish working on it. It's all thick (4-5m...

Making my little research on vibration isolation, I came across those fantastic pictures hereof how Proscenium suspension is made:http://www.6moons.com/audioreviews/walker9/2.htmlI've always thought that he uses some custom-made pneumatics,but those ...
|
de Charlus, the rack is still not at my place after the rework (it turned out to shake like a gelly fish--I refer everybody interested to the lencoheaven thread).I'll post pictures and some details when it's here and the slate is on it's place.Cost? ...

[quote user="Paul S"]N-set, I've seen and done plenty of all-concrete construction, including floors and entire roof structures, standard, pre- and post-tensioned, and also shot-crete. Ironically, concrete itself actually gets stronger over time, fo...

I will upload some pictures and more details when the rack is at my place in few daysand pre-assembled in it's "version 1". In the meantime, for those with masochistic tendencies, here is a diary of my ignorance on the subject: http://www.lencoheaven...

Paul, wood it is not almost for sure: there was hardly any wood and wood craftsmenavailable in Gdansk in the 50's when my building was built. Almost completely (95%)destroyed in march 1945 when pushing the Germans out, it was rebuit mostly usingreinf...
|
Paul, I thought about the wall mount, but eventually decided to go with a more universal, pref. end of life solution, I could place anywhere. I've never had a dedidcated rack, a time to have one.The result is a slate-on-steel-frame 500kg mastodont, I...

...and nobody has taken up my GU81M idea ;(?ah, low morals and small balls, guys......

You are very welcome! Keep in mind however, that I do not pretend that my "sound" is anything special at this stage--I'm very much on thebeginning of a long journey, progressing slowly. What I offer is a chance to listen to O2MkI with a +/- advanced...
|
Scooter, if you happen to be in my part of the world, I invite you to stop by my place (I provide accomodation right in the city center) and listen to my EMT with O2.My Staxquiades won't be ready soon for sure, but my source is well operational(refur...
|
[quote user="scooter"]I think that is a VERY interesting issue to think about in the broader scope of sound reproduction with full-scale systems. [/quote]I'm not sure it's so interesting in the context of speakers--you have much more parameters to pl...

Hi Scooter![quote user="scooter"]
I have tried the SR-009, SR-007, SR-507, and SR-407 many times over a total of some 5 hours with a variety of sources but always with some Stax branded amplifier. Every time I thought / suspected that the big Stax...
|
Scooter, being myself a Stax listener, have you tried portable Staxes? Model 001 or something like that.I've never heard them, but I'm wondering what they are worthas an interesting attempt of portable electrostats.Cheers,N-set...
|
[quote user="de charlus"] My proposal was to more or less combine the drivers from said systems in a single system, structurally similar to the Cessaro Gamma[/quote]...which is the Macondo topology only quite a few years younger. Either Cessaro reach...

I'd vote for mapping the above two posts to the acoustic systems knowledge tree....
|
de Charlus,I have been chewing on +/- similar ideas (broadly speaking: what is a chance and how to make an advanced horn acoustic systemfrom a scratch with zero prior experience), but unlike you, I'm not yet on the level of seriously starting it due ...
|
Wow! I had no idea such things are now published on arXiv! It has grown a lot from only fundamental physics.Will read the paper, thanks scooter...

There was probably some misunderstanding of intentions and perhaps my English is too agressively sounding, but nevermind, this is not important.More to the subject:[quote user="Romy the Cat"]What makes a TT to sound good is mystery to me.[/quote]I te...
|
I do not know the guy who has written it, maybe he is an idiot, but anyway I'd defend his page.As far as I understand he is a DIY-er (?) who attempted his own TT, inspired by high mass belts.Well, that's life--we all have to make some choices at some...

An interesting link from Lencoheaven:http://www.soundfountain.com/beltdrive/belt-drive-turntable.htmlsimple...no BS......

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...

[quote user="Paul S"] I would like to hear something more rigorous and complex than "the usual" music the DIYers use to "prove" a design/system.[/quote]Was my thought too--"a girl with a banjo" audiopedophile(tm) crap.[quote user="Paul S"]Unusual TT!...
