Miracles in Audio, by luck, by good choices,by design or by tweaking...

I owned a low cost headphone for many years, the Fostex TH7B, first version( a new one close version exist Fostex TH7BK), semi-open headphone...I was never completely satisfied by any headphones I ever owned: Hifiman 400, Stax basic lamda, Stax 5 gold,Akg 340,Akg 701, beyerdynamic 990, and T150... Because in each of them with all their qualities I never listen to at the same times, a confortable headphone with natural timbre and voicing, with a good imaging and a realistic soundstage(not too close to my ears)...


For the last days I tweaked this Fostex, to damp his internal resonance I used sorbothane, I put some shungite stones at the exterior part of the cups and I use some Herkimer diamond in the interior pads( 3 at 120 degree) … Now this low cost headphones crush all my others if I sum all his qualities... For example his mids and voicing cannot beat the AKG 340 but among all my other headphones it is the best that is near that mids and it is more confortable, and with longer cable than the 340...His imaging is better and more realistic than the 340 etc etc...It is the same if I compare with the others...


His most important qualities is natural timbre and clear imaging,very precise pinned point accuracy and natural, so clear it crush for that ALL the others to dust...In the French audio circle the reviews were more than very positive few years ago...Diapason d’or and choc Classica...I am not the only one impressed buy the ratio quality/price... But remember that thesae reviewers dont tweak their headphone...The difference between before and after the tweaks are staggering...


Yes Miracles happens in Audio: cost is under 100 American dollars... Few years ago they cost me 50 bucks new... I never dreamed that I will go back to headphones...


I will enjoy your miracles stories of any kind ….My best to all...

Addressing vibration control of a component
can be attacked different ways.
I was happy with the way I was supporting
electronics and speakers.  Now this is enhanced further by
minimizing the vibration of the electronic piece itself.

I have used various foam pieces of different density
and size, shungite, and PPT mats.  The "spring sandwiches"
work as well, or better, than those, for me.
I use them exactly in the configuration in which they were shipped,
with no manipulation of the springs.

They are easy to place and cost "peanuts."

Do you prefer listening to music with the ionizers
"on" or "off?"  The tradeoff is the enhanced effect
versus the slight internal noise they generate.

Do you notice a difference in SQ when
you leave them running all the time EXCEPT for
the times you are listening attentively?

I just posted great results with three S.G.s (usb versions)
and 10 foot cables.  I found a plug online that has 3 ports.
Too easy!

I have both Synergistic Research hfts and DIY hfts.

Placing one hft in the middle of the S.G. is very nice.
Maybe I should try the hft mounted on a Shungite rectangle,
attached to the S.R.?

Thank you for this...

Are you using the skid pads?
Did you compare the sound, with and without?

I understand the "sandwiches" in your system;
did you evaluate the sound without them,
employing ONLY the foot pads, and possibly
varying the number of springs?

These are great on top of components and shelves, and on transformers.  They come fully assembled, too.
Great value.

Now you must experiment with placement of the springs on top of electronics!

I have been using silver 3M tape, 2" wide.
I bought a roll to join some ductwork, to vent a clothes dryer.

I find it is probably thinner and lighter than the copper
tape I was using in audio applications.  I like the way it
"smoothes" sound when applied to different surfaces...

Hats off to you, Mahgister.  I received the "family" version
of moskitofree from France.  I agree with your comments.

The device probably should not be used when music
is just meant to be a backdrop for other activites.

When the device is "on" it simply brings the music
closer to you, and you become more aware of everything
you like, about what you are hearing.

I have used the device to treat cds, wanding for five rotations,
before playing.  And doing the same around each ear.

The ionizer is silent and does not really move much air.
It is making a huge impact in what I am hearing, and is a
most pleasant surprise!  A keeper, for sure.

In my experience, the effects of the Moskitofree product
is enhanced by using an air ionizer.  I keep the
former "on" all the time, and use a portable air
ionizer for only 15 minutes before a listening session.
It is as if the effect on the air in the room is supercharged.

As the height and location of a Schumann Resonator is important,
I have found that the Moskitofree placement can make a 
difference.  Insted of above my head and behind me
(on a shelf) I am now placing it on the floor, between the
speakers, angled upwards and  towards the listening position.

If air is the medium through which all sound travels,
doesn't it make sense to pay attention to changes one can make
to the air, and the impact on sound quality?  I recommend
Moskitofree to every serious audiophile...

Please generously post the link to the Chinese ionizer?
Thanks very much.

If you turn on and plug the ionizer or MOSKITOFREE into a
charger in your cigarette lighter, the music in your
car can be transformed.  As if you upgraded the radio head,
speakers, and amplifier!  For peanuts.
