A Copernican View of the Turntable System
Raul makes a reasonable point.Whilst it is in our 'audiophile' nature to be skeptical and delve into philosophical discussions regarding our understanding of the playback system, there has not been one report from those who have actually tried the...

Hi Nick_sr,The Copernican view of the armpod and tonearm as the centre of the turntable system, is predicated on the fact that the armpod is an 'immovable' object.How that is achieved is open to debate.I prefer to see mass (and plenty of it) conce...

Nick_sr,The approach you describe is a common one and has been in use by different manufacturers for decades.This thread is simply proposing a differing approach albeit one which still maintains the geometrical relationship between tonearm and tur...

I believe that Pryso and In_shore are correct in the fact that the air-borne sound pressure levels, affect the room's fabric to different degrees depending on their materials and structural means of support.This transforms into 'structure-borne' f...

On a serious level.......it is often difficult to isolate 'structure-borne' feedback form 'air-borne' as the 'air-borne' feedback can be absorbed into the equipment rack or floorboards and thus mutate into 'structure-borne' feedback affecting your...

Hi Chris,I believe you may have found the cheapest machine shop in the world?$48 for four solid stainless steel legs including machining them to their points?Simply amazing......cheaper than concrete perhaps?The only thing that bothers me about th... 
Heaven or Hell
No it's not your mind.It has been happening to me for the last few weeks whereas it rarely did during the previous 25 years.They have coincidentally upgraded the power lines in my street during this time but nothing visibly being done over the las...

Hmmm Jonathan,Sounds like a typical listening room to me? :^)Lewm,The shrinkage of concrete is greatly determined by the water content.....the greater the water content, the more the shrinkage. (George knows what I'm talking about).I doubt that co...

T-bone,Not sure I follow you on the tip-up and down bit?If you want a glass smooth finish on the concrete?.......that is normally achieved by steel trowelling which is why I suggested screeding of the top surface with a metal flat edge as in a ste...

Concrete armpod indeed!Why not Audpulse?Here’s the design:-A sand and cement mix (3:1 or 4:1 is fine) is available in any hardware store in small plastic bags.Now for the mould…..select any hollow metal tube section from 100mm diam. (4”) to 150mm ...

Dear Nandric,I like your humour :-)Unfortunately, sending one of my pods to Europe (including some specialised packing to protect the valuable object).....would cost heaps.....not to mention the Project Manager's time and effort to organise the bu...
