Question for Mr. Jadis

[qguy]

Maybe its because our ears are hearing the sound from the part of the ribbon which is directly in front of us...shortest distance from Ear to LS ???


Does this mean that you dont notice sound coming from the top area of the ribbon ?



OT : Maybe that why humans and most other species have their eyes in line with the ears for better sound and sight coordination...just imagine if the ears were at stomach level ..hehehe

Jadis,

I'm using a pair of bookshelf and the image of the singer is deadcenter between the LS, when your using large Ribbons like the maggies, how is the image of the singer presented to the listener since the ribbon is producing the full range from top to bottom...

For some spectacular reasons, the center
image is still at eye level; I cannot fully explain that, perhaps it has to do
with room interactions with the speakers. )

qguy,

nope, it does not sound like anything is higher than ususal..very amazing indeed.
i think this is called psycho-acoustic effects

[ihatejazz]

ihatejazz,

most certainly you need not be guilty.
you are the analogue container van king, far from a troll.

why not as the Philippine distributor of CLEARAUDIO, VPI INDUSTRIES, AESTHETIX, GRAHAM ENGINEERING, MUSICAL SURROUNDINGS, MAGNAN CABLES?

Pasikatin mo naman ako pa minsan minsin

Jadis,

Not sure if this was asked before...anyways...How do you describe an Audiophile ?

Jadis,

Not yet.

I would say an audiophile is one that:

1. Daydreams about audio related stuff.
2. Willing to chat on phone during office hours with an audio buff
regarding audio with reckless abandon.
3. Does not care about wife's nagging re spending for audio.
Nag in nag out. ( for the married ones )
4. Will drive from north to south of Manila if any software arrives
from an importer.
5. Will bring audio magazines to work and actually read it there.
6. Willing to make DIY stuffs whether it's for room acoustics or
even hardware.
7. Believes in the effects of the room to the sound of the equipment.
8. Loves to tweak with the system.
9. Loves to upgrade components if given the chance.
10.Will feel at ease conversing about audio with a stranger in an
audio store; and when calling a 'mutual friend audiophile re
some info about audio for the first time, will talk to each other
like they've know each other for years.

I guess these are what I observed as 'acts' of being an audiophile.
Not all audiophiles will have all traits, but all will have most of them,
imo.

dear mr. jadis

i need your advise with respect to repairing gear. i have a 12 year old conrad johnson evo 20 preamp. the left channel of the phono is starting to exhibit crackling sounds. the tech guy in CJ-USA said that its probably a bad resisitor or cap. short of sending it to the states, what would be the most efficient way to solve my problem? what would you do if you were in my shoes?

[jadis]

detubo,

I wouldn't even consider shipping it to the States for repair. The freight costs too
much. There are local technicians here, of late, mr ihatejazz recommended a good
one to my friend and his gear was serviced well. Btw, have you tried replacing
the tubes to rule them out as the trouble-maker?

Bring it back to the gentleman who sold it you. He will surely repair it. You have his warranty. Or even better, buy an AESTHETIX CALYPSO & RHEA. Make My Day!

[detubo]

i guess you mean rene. oo nga pala. i tried replacing all the tubes. same thing. thanks for the suggestion.

si santa georgie talaga. saan na si aesthetix. baka mauna pa si art audio vinyl one dumating!

[jadis]

detubo,

and to talk from experience, if the unit will not be properly repaired by a competent
audio technician here locally, dumped it. that's what i did with my ja200 amp. two months
of waiting for the technician and having him bring me to a roller coaster ride of agreeing
to come for home service and not showing up...that is too much...an audiophile should
not be a slave of his equipment - that is one of the commandments of audio.

Sorry to step in, Mr. Jadis, just to help our audiofair hero Mr. Detubo.
Oh ayan Tito ihatejazz, nagpaumanhin ako.

Mr. Detubo:
Typically crackles from a tube preamp are caused by faulty tubes. If that is not the case, the voltages have risen in the circuit which overdrives the tube, then causing the strange gremlins to rise and make popcorn. The CJ techie is right in saying that it must be a faulty resistor which had gone down in resistance, therefore the circuit voltage/s went up. I don't think it's a capacitor though. These polyprops and polystyrenes are usually tough.
Another cause would be the brand of tube. CJ's have been known to be finicky in tube selection. Some brands gives it higher voltages causing the noise. One channel may have noise while the other is still whisper quiet due to the different tolerances of the channels. So even if you switched tubes, the noise still appears in the same channel.
Hope this helps

Crackles and popcorns from tubes - if random and not continuous can also come from loose or dirty tube sockets. This can happen due to excessive tube rolling and nos tubes that have accumulated decades of grime on their pins!

[detubo]

thanks a lot guys. buti nag tanong muna ako. i tried changing the tubes 3x to no avail. dirty socket? maybe. feel ko baka resistor nga. i'll just have dr. rivo give it a full physical examination. again, thanks

[jadis]

noctilux,

you are most certainly welcome to step-in...your help in any way in inputs is
always very welcome. all indeed are welcome here to share.

Dear Mr. Jadis,

I a Louie from Zamboanga City, a casual observer here.

May I have your thoughts on Naim (PRAT,flat earth) and Subwoofers (esp. REL)

Thank you.

[jadis]

RU9,

Sorry Louie, I have no experience with the Naim Prat and the REL Subs.

Mr Jadis,

I previously owned a pair of maggies and I like very much. Unfortunately one channel conked out and the unit is still with a friend for repair. Am presently using SF Concerto. If I remember correctly with the Maggies my listening was limited to vocals and small ensemble jazz music. When I play the old classic rock and sometimes when I'm feeling long haired I also play my led Zep cdees, the sound becomes compressed and I really have to cranked up the volume. Could it be the Citation 2 60w/pc amp am using or the placement?

[qguy]

Jadis,

in your opinion, what is the most important component in the system ?
Loudspeaker, Amp or Source

[jadis]

Chito B. Gayos,

The Maggies are not efficient speakers. Ususally about mid 80s db sensitivity. I would
use them with at least 100 watt amps so you can crank them louder. I can play rock
at satisfying levels, both with my 160w Jadis JA200 or presently the 110w Audio Research
VS110. I don't even feel now my system lacks power for rock music. I could even play
loud disco CDs ( Madonna early dance music ) and feel very satisfied with its volume.
Among other things, the Maggies can exhibit an upper midbass 'hump' or what
others call the Magnepan 'slam'. With improper positioning, this makes some rock
or disco music sound overbearing; and pulling it out from walls is one solution. The
nearer it is to the back wall, it reinforces this 'slam', which to me, does not sound
good at all. I would agree with you that perhaps the compression you hear is due
to the small wattage your amp gives,that is usually the sign of an amp lacking in
power. I heard a Krell 250 class A amp drive a pair of Maggies2.5 before and it
was rocking like hell, bass was so tight and controlled; it was actually incredible.
What the Maggies cannot handle, imo, is large orchestral cresendos like those
Telarc recordings, the speakers probably will be damaged if one cranks it to
high volumes.
