About Me:

I am a lover of music and books.

Interests (Hobbies, favorite activities, etc.):

Wanted: high level audiophile experience for the poor,
under 1000$ for all.

What I do for a living:


Headphone Inventory

Have and listen to :

HIFIMAN HE-400: ( famous reputation for the ratio quality/price ) After inserting inside the cups near the driver pieces of sorbothane duro 70 1/4 inches, the sound level vastly improve, and these cans now compete with my Stax, with a great contrasting sound, details,and acceptable soundstage, ideal for jazz...I try the grill mod. with success, more airy and musical .... The crystals mods. improve them a lot also.... I am in love for a second time, on par, but very different than my first choice Stax SR-5. (classical)

STAX LAMBDA NOVA BASIC : with sorbothane on the headband a truly extraordinary gem in the ratio price/quality...

STAX SR-5 Gold ... what i can say? No real defect, i said that not by by listening to a measuring instrument but with my ears , they are only extraordinary musical, really high end for the poor ( 70 dollars + sr6 sb energizer)) but kill many hi end headphone , i will not name it here...But Ken Rockwell name the Senn hd 800 and he prefer the Stax SR-3 without sorbothane, i cannot comment because i have not hear the hd 800, but i dont want to hear it now ever, too high price for what ?

Have but listen to no more :
Fostex th 7-b + EMBER amplifier( for the price,60 dollars in canada, i think that this dynamic headphone is marvellous, the best kept secret in audiophile headphone) I think his rendering of the instrumental timbre and midrange is very musical for a headphone of this price...this headphone has the Golden award 2013 of the hifi French review Diapason, if you want to know why, buy them, ratio sound quality/price over the roof...Stax and he400 are 7 and 5 times their price but certainly not many times more good sounding...If you are poor rejoice! the Fostex are Audiophile stock despite their appearance and color...the sorb mod on the Fostex are a great upgrade of the upper bass clarity..

Audiotechnica ath-m50 ( closed headphone only good without being exceptional )

Headphone Amp Inventory

Have and listen to :
Sansui Au 7700 extraordinary Vintage bargain with a completely separate pre-amp section and a tone+filters control section audiophile grade....
Someone said: «For people that have owned Sansui amps, there seems to be two camps.The first are the owners who love their Amps and will never sell them.
The second are the owners who sold their Amps and wish they hadn't.»
With my StaxSR-5 and with the Mission V60 speakers an extraordinary sound at low cost...i use it like a pre-amp with the Stax lambda nova basic and the srm 252s +sorbothane mod. I want to try someday another amp. but i am afraid to buy another because the many qualities of the Sansui made upgraditis an obsessive absurdity... remember that this amp was in the totl in the world of 1975...

Have but listen to no more:
Ember project ( very good and very versatile,very beautiful, with the 6J5 tube family incredibly better than with my 12 other tubes, including the 6sn7 and the dual 7193 family ) surprisingly high ratio quality/price/flexibility...its pre/out drive also the Stax with more body or the Monsoon internal amps with more soundstage ...It was some time ago the Amplifier of choice of my Fostex and Hifiman HE 400

Stax srm252s

Had :
Hitachi receiver sr 904

Stax smr-xh (at used price a bargain capable to run many stax headphones)

Aune t1 tube dac/amp ( good synergy pairing with the ath m50 and the fostex, not with the He 400 for my ears)
Pa2v2 ( i dont use it now, but for the price interesting deal )
Bravo ocean tube amp ( good synergy with the He 400 and with the AKG 701)

Source Inventory

Beresford Bushmaster mkII with Ankaka Battery charger ( a pure marvel for the price)+sorbothane mod.

Hifimediy asynchronus usb Sabre DAC + sorbothane on it ( 57 dollars and i am sure one of the best dac less than 200 hundred dollars, and an optic converter, all in one)
+ hifimediy usb isolator (that make in the chain an audible difference to my ears)+ sorbothane on it

Aune t1 tube dac/amp. ( bad synergy with Hifiman He 400)

Cable Inventory

Morrow ma 1 interconnect rca cable ( quality/ price ratio very good to say the least ) + Morrow Ma3 and this upgrade with the ma3 make a big difference...+ excellent King Valab optical toslink cable (great upgrade from cheap cable)

Power-Related Components

Paramax pm8-av power conditioner made a difference also... bought it used for a cheap amount...made a great difference and protect your gear...UPDATE: i have upgrade for Panamax 4300 EX with joy, what big difference it made compare to the basic panamax, i bought it used for 20 % of msrp... a bargain for an audiophile experience...

Other Audio Equipment

My first choice speakers :

Mission volare V60 2 way speakers + sorbothane compressed with concrete slab load under and on top of the speakers, pieces of sorbothane also around the membrane with greater sound results.... the sound of these 75 dollars speakers used is now so good, thanks to sorb. mod,+ room cheap acoustic treatment with diverse pieces of foam that it is impossible to beat them unless to buy i dont know which very more pricey speakers ...Bi-wiring the Mission speakers make a difference and clean some haze around the notes, they are especially made for bi_wiring and i must say that the difference is audible, especially with the sorbothanization of all my audio gear...AFTER THE CRYSTALS MODS. of the gear system, and of the room, the mission speakers were resurrected to another level...ASTOUNDING...

Monsoon MM 2000 4.1 active powered desktop speakers (4 planars satellites with a sub)...Very good for the price paid used...

had :
Swan m10 2.1 multimedia speakers ( quality/ price ratio impossible to exceed, it cost me one dollar on ebay and the retail price is around 125 dollars) the sound is very musical, and if you are on a tight budget dont kill yourself buy it....You will smile ...I give them to my son...

Audio-Related Tweaks

IMPORTANT NOTE : Sorbothane feets or patches are miraculous product for vibrations...They contribute to produce a more clear bass and imaging under my Monsoon subwoofer and directly glued on my planars panels ...They are no less miraculous in my Stax SR-5 , or HE-400 they transform it in my Holy Grail... All my gear are sorbothanized...Around the membrane of the Volare V60 sorbothane made miracles...ALWAYS USE DURO 70 self-glued SORBOTHANE ...

THE MOST IMPORTANT THREAD IN HEAD-FI is this one: «Damping Mechanical Resonance Distortion of STAX phones with SORBOTHANE: LAMBDAS, SRXIII PRO, SR003, SR00, the SIGMA and various non-STAX »

The most important thing to remember if you have speakers is ROOM TREATMENT for sound, i attempt it with low cost, pieces of foam, or different kind of foam also and the results were ASTOUNDING... No upgrade in cable or new speakers compete with a room treatment...It is so good that my speakers are now my number 1 listening device...

FIVE Quartz crystals( also topaz amethyst tournaline)distributed from the in and out of the power conditioner to the breakers,passing by the outlet also, clean the line and produce a spectacular imaging stage, the sorb. clean the resonance inducing a better musical timbre, but the quartz impart the line with less noise, inducing a better imaging soundstage. ..These two tweaks are the greatest discoveries of my audio life...

One Bybee signal enhancer over the power transformer of My Sansui give the final touch of refinement(very audible with all my prior elimination of bad resonance with sorbothane)...Perhaps someday i will bought 2 others for experiments...This passive enhancer must not be your first buy, but after all others improvements , wow! i am very glad to have stumble on that....
