H J s system !

[MylesBAstor]

Just ordered some 6922 tubes and Ecc 83 s for the cat phono section , i have not been able to sell the Ultimate mk 2 (or "pre" legend whatever it is )and buy a real legend .
I am now gonna try to make the phonostage a bit quiter with"better " tubes , ive ordered 3 pieces of 6922 genelex gold lions and GL ecc83 and tungsol ecc 83 tubes , i might also buy a extra step up someday for mc s as well
See if it works , i quite like the pre and dont want to let it go on the cheap

You might think about some 60-70s Tesla ECC83s. They're better than the ones you've listed (I've just finished doing a comparison of different 12AT7 and 12AX7s in a phono stage am reviewing!). Much like the Tele sound. I find the GL ECC83s just big and bold and tubey and very closed-in sounding. The Tungsols would be my second choice. Don't ever try the JJ/Teslas.

Thans for the advice gonna look into that, how is the noise floor of that tube ?,
I am primarily concerned of getting the noise floor down , and those i bought were low noise ,low microfonie candidates (i read on the website ), i also read somewhere the V 1 tube is the most important in the circuit as it is the first in the line from the turntable wire ,so there needs to be a good one , ive got to experiment on that too.

Ps the tungsols i ordered are the high gain version , see what that does to the sound

I am still figuring out which model i have, its not a ultimate and its not a legend , maybe somebody from CAT can shine some light on the matter , the serial no is 10307

 

[andromedaaudio]

Tried the genelex and the tungsol , the genelex are very quit tubes and good sounding too , the tungsol ad some noise in the phono stage ,in my experience .

 

[andromedaaudio]

I moved the system to the corner of the room , and added some dampening rugs , the sound is certainly better .
The speaker project is not going as fast as i would like , , as there is serious money involved and its not so easy for a small designer /manufacturer to get things done by big companies , most they are interested in is making large numbers of them
MDF/aluminium okay but resinbased designs is much more difficult as they are hard to manufacture and can only be done by specialized companies , its much harder on the tools than aluminium which would be my second choice

Are those speakers your own design HJ?

 

[andromedaaudio]

Off course

 

[Johnny Vinyl]

Off course

Very nice! I really like the shape and choice of finish! How do they sound? Perhaps a point of reference to a known brand?

 

[andromedaaudio]

Thanks, its a basic compact structure and the sloping top lowers the center of gravity .

The only speakers i ever bought were dynaudios and avalon avatars , how do they sound ???
Difficult to say , the best would be if they had no sound at all .
To me its a 2(and a half) way system to the maxx , having two stiff 8 inch woofers the system can move quit a bit of air so can sound pretty powerfull.
If i must describe the sound it would be like glass with the creamy mid /low end of the nomex kevlar units .
Essentially neutral ,when i bought loudspeakers i always found something that annoyed me or thought i could do better.
NO bass overhang very annoying , very spacious ,the sound is free of the speaker, very dead cabinet and very easy to drive ,8 300 B watts can certainly be powerfull /forcefull,flat FR with very slight downslope (intentional)

My reasonably priced speaker preferences are magico V3 ,avalon ascendant or eidolon / vision as its now called and watt puppies

If I ever make it back home again (I really should) I'd love to hear them!

 

[andromedaaudio]

Sure youre welcome , holland is still there
I do like canada also by the way i was in " TO" for 3 weeks some years ago

 

[andromedaaudio]

after testing quite a few mids/tweeters (testing without a bass speaker ) , this is what ill use with my next project , no more accuton , not the most natural in my expirience and not the most revealing, i followed the mainstream quite a bit , but not anymore
Love the Boulder more and more

Bought a beautifull piece of audiohistory ,plus i can now record as well , i still have to see the first cd player able to do that

Interesting...similar cabinet shape to the FM Acoustics Speakers. Why did you choose this shape? Curious to learn. Thanks.

 

[andromedaaudio]

First of all its rigidity ,i like to keep surfaces small if i can and well braced , the closed mid in the 3 way doesnt need a lot of volume to work best, panelwitdh has to be made small /surfaces also ( is not an absolute with other materials )
- diffraction , having a large wide baffle most speakers have a tendency to become less spatial and become boxy sounding
-low point of gravity /stable to place
And its design dependant , all my designs are X perimental this one as well , with the new units this is an exxelent speaker , the bass is 11 inch ETON .
This is also supposed to be a speaker with a relatively small footprint /elegant design , not a speaker that fills the living room, if therefore a bit of bassenergy is offered than so be it

I might have also an aluminium anodised frontpanel made for this one or HPL (high pressure laminate) " if that company would be more cooperative it would have been done already"

And also important , the way the air moves in this model is reflective it hardly has parallel walls, plus it has a internal structure which is an obstakel for fast moving air , it gets obstructed to a certain degree, there are not so much sound waves going back and forth in this loudspeaker

Cool. Thanks. What do you think of the MTM and DAppolito layouts?

 

[andromedaaudio]

Well first of all MTM is a great way to get greater system efficiency , secondly the dispersion will change as compared to one mid unit and tweeter, the imaging of the system becomes different
This will be a logical thing for me to try in the next project , as that will be a high efficiency true full range project , 11 and 13 inch woofers , which are also a bit the maximum dimensions for me as going larger means also often having slower bass , i like fast deep bass.

Dappolito is merely a name for me , i dont follow his filter topologies regarding mtm config .

interesting read...thanks. Yes, that's right...very, very much looking forward to seeing more of your big MTM, 11" 13" speakers!

 

[andromedaaudio]

Me too , i hope to show some of the MTM cad printscreens the coming weeks , but i will not show the complete design that has to be a secret until its ready
It will have a industrial high tech look
Making a new design is adventurous , you always run into things you didnt expect soundwise, mostly for the better .
They will be made from 6082 t 6 aluminium , which is the improved succesor of 6061 T 6 aluminium , very good for machining very strong and very good anodisable .
Hpl has a density of 1400 kg/m3
6082 has 2700 kg /m3

Heavy ,inert ,strong and highly corrosion resistant !!!
After they have been anodized the layer will be stronger than hardened steel

Its used in :
High stress applications
Trusses
Bridges
Cranes
Transport applications
Ore skips
Beer barrels
Milk churns

Higgs cable s instability

I use quantum mechanic cables with higgs particle connectors .

No serious , i use the same as the internal wire for the bass/mid section , i use the small diameter for the tw section .
Its multiple strands of copper ,silverplated , teflon insulated

The only problem with Higgs connectors is that they seem to have a finite lifetime, maybe 100 billion years, but who knows? No self respecting audiophile would be happy with such short lived components. Short break in time, though.

 

[andromedaaudio]

Higgs particles ......you cant live without them

The pieces are coming together , the tapes have arrived


DSC_0029 by andromeda61, on Flickr

In a couple of weeks the tapemachines will arrive , some time later the new speakers , together with Zanden Boulder and CAT i think my 10 year audioquest will have come to an end .
Finding a way through all the " audiophile missinformation " has not made it easy , but there is also good advice .
I think after that, i will consider my audiophile ass retired , and i will pursue other interests, the loudspeaker / sound challenge is mostly over.
