Hifi Rack

Hi HifiAshok

Try Indian rosewood also.

 

[sidvee]

hifiashok - a similar application to what I was suggesting (with your application being slightly different with the top resting on the brass footer tips). I used the brightstar audio platform in the past filled with sand under my Cd player and could definitely hear the improvement in sound.

waiting for members like kamalji to get better, manavji to shift to g'gn (and a lot more who also are HFV members) to contribute to our continuing the learning. i remember not being able to objectively reply to asitji's query when i intro'd vibrapods and vibracones to my set up.

would love to contribute! it looks awesome, even now! i doff my hat at your effort sir!

 

[hifiashok]

I hear you hifiashok. One option is not to fill sand or lead shot or whatever ballast you are using uptil the footer points, rather maybe a few mm below the tip and that way both the objectives will be achieved.

definitely a triable thought. will inc. listening sessions that we often have will cull out the differences/+ves. thanx for the suggestion, and well in time before finalisation.

btw, presently, the no. of components is just the brass, SS and wood. adding the sand will add to the number of variables. also, presently the brass cones are only embedded in the wood. with the sand intro, the brass cones would have two addl. points of common contact, one the wood frame and second the sand, other than the SS headers.

Hi HifiAshok

Try Indian rosewood also.

was under the impression sagwan - teak - indian rosewood are all the same.

imho, there are two approaches. one, with sand, and sand only. the other, with cones, and cones only.

sand helps in one way. cones, in a very different.

mixing the two approaches MAY not be the way, though i could be very off the mark here.

btw, i had a long series of eMail xchngs with BSA when finalising my existing rack. they had suggested various IsoRocks, IsoNode Feet and Little Rocks. however, since they went the platform direction, and i was looking to a stackable design rack, things did not work out.

Hi HifiAshok

Teak and Rosewood are different species. Rosewood is Seesham. Sagwan is a teak variety. Teak and Rosewood platforms sound very different

Hi HifiAshok

Teak and Rosewood are different species. Rosewood is Seesham. Sagwan is a teak variety.

yes.... Dalbergia Nigra, Dalbergia Latifolia & Dalbergia Sissoo for Rosewood/Seesham and Tectona Grandis for Sagwan. Genera and Species wise.....

Teak and Rosewood platforms sound very different

more options..... :sad:

Hi HifiAshok

I have had greater success with woods that are used to make musical instruments. Like rosewood or ebony. To the best of my knowledge teak is not used in manufacture of any musical instrument. Generally i find the tone very nice when ebony or rosewood is used.

Hi HifiAshok

i feel ebony wud be tuff to work with (carpentry/machining wise), and expensive to source (unless i hav one of my course-mates returning from congo UNPKF carry some). i also did not know ebony was used in (main stream) instruments. will look into the rosewood option. however, is a dark wood. i was looking to try and mate the veneer to the arista cherry baffle. i think i'll do three options of the ply part (in the pix) to start with, to mix 'n match; teak, birch and rosewood.

Let me add to the confusion. Bamboo is also a good option. It tends to work under heavy power supplies/transformers. So it could work in your case. Most kitchen cutting boards are made of bamboo. You can source it pretty cheap.

 

[hifiashok]

.............merde!

Honestly HifiAshok the idea is not to confuse you. When one uses wood, stone, or acrylic under a piece of equipment you end up tuning the sound. Since you have taken the approach of tuning, try various types of wood and see what sound you like. I am saying this from my years of experience of tweaking. For example, i think Asit uses a stone under his Leben. Anything you use under an amp will change the sound. The point is what works for you. Changing brass spikes to SS spikes will also change the sound. SS is more neutral. Brass will add a color to the sound which you may or may not like.

 

[hifiashok]

ges there aren't any easy short-cuts to this.

wil need to go step by step and keep learning....

btw, bamboo; definitely not trying.

heres an absolute monster of a custom rack being designed
im temporarily going to call it the "cranky" rack because its being made for a very cranky friend and ; building it has got me a bit cranky too

Industrial design
Designed to hold 6 pieces of equipment ( 3 on each side )
and maybe a TV or Turntable on the top

for its size i believe its probably one of the heaviest racks in the market (international mkt included) -
(i needed two members of my staff to help me assemble the monstrosity)
All members are SOLID AL columns, the bases are 3 inch in diameter

i havent bothered to weigh it plainly because this is MAJOR overkill
you could probably park two hatchbacks on the two sides of the rack and the rack wouldnt break a sweat


Anyway
the rack is meant to be a shelfless design
one can load equipment directly onto the supports without shelving
or alternatively one can have shelves too

isolation will be tackled later
stay tuned for that

below is only the rough frame
equipment/shelf supports still have to be press fitted and bolted

 

[magma]

Heres the Type 3 Gamma series design that i had been working on for a couple months now

following is only a prototype
the original signature series will use much larger side columns
the shelf supports and horizontal stuts remain the same though

Rack is made from extruded cross braced aluminium members
Infinite height adjust on each shelf (each horizontal strut slides along the side T slotted columns and can be locked in any desired position)
Isospheres for the Base
Top can be a heavy plinth for a TT

only the rough frame is depicted below

shelving will probably be teak struts or a granite wood composite as shown in the last pic which is not clicked by me but is a google image for a sample( that is actually reserved for a reference series i am working on now )

The treated granite offers a high mass hard surface whereas the softer wood(compressed artificial composite) applies its damping and draining ability

The result is a sonically-neutral platform that will enhance clarity and detail, without any of the harshness usually associated with the use of crystalline materials.

a big argument is that granite and wood have properties like the two poles of the world.
Alone they make not so good shelving options and most audiophiles never do use them alone
but combine them and they do work wonders

details on my website later

a small project just completed for a fellow audiophile
to house
2nos Ayon audio tritan monoblock amps (on the two pedestal stands - granite base)
A Ayon audio Skyla DAC, a Ayon Audio CD1, PS3 apple tv and some other gizmos (central main rack)

 

[Bluu]

Beautiful as usual! Is the shelving glass or Plexiglass?
