Hello to all! my name is Alexander, of Ferrara, 30 years, I've been passionate of high fidelity since 1991, when I acquired my first system.

I recently came across Hi-Fi friends, and prior to that I read TNT for a few months. I would have preferred to discover them before! True of any passion , I spent a lot of time reading and 2 months (of listening at several retailers) before purchasing my first CD player... given the $260 (USD)paid, it was not worth the effort given the quality of consumer products was an issue. As well as more that I had a pair of Bose Interaudio 3000 XL speakers and a Marantz PM30 amplifier. Not too shabby, above all like synergy.....
CD Players that I possessed in the course of the years?

1)JVC XL-CZ442BK (I do not have it more)
2) Philips CD 230 (super-economic multi-bit but hour in phase of modifications... with escape to valves, feeding, etc)
3)Aura CD-C50 (sold)
4)Sony CDP-CXE200
5)JVC XL-CZ 232 modified.

I have carried out in the course of these years listening sessions with systems of friends, I have listened to a Pò of all, and have decided that in spite of the quality of a member it is one characteristic objective and often measurable technically, to the end which counts is not alone the final sonic result, but also and above all the fact that that sound piaccia subjective (always presumed to us that the subject in issue has a minimum of idea of as feels one instrument from the alive one, and one minimal musical culture), but in the range of the fidelity to the original sound.

The problems of reproduction of my system had been resolved nearly of all with the Aura CD-50(credo still imbattuto like musicalità,

MODIFICATIONS To 232 JVC XL-CZ Monolith Configuration by Sphere

As far as the modification to the JVC-CXL-CZ232 I preput that they are not a technician neither an expert. I have only read in the course of the several time articles on Audioreview, Sound, etc., and in December it has come to me wants to acquire the JVC why in the ' 91, when I had the other JVC, I was perplexed and it they have been until today: why the a lot applauded P.E.M. dd converter it was not never successful, in my system, although its musicalità, to leave me soddisfatto??Anche with widens and various cases had always something that did not go, and did not understand as it could play badly in spite of the positive critics of the press, even if can sure say in what consisted the problems with model XLZ-C442BK of the age (and riproposti with XL-CZ 232 in smaller measure):

1) Insufficient definition (little details) on the high mean
2) Roll-off, with low and up lower-middle a Pò opaque and tending to strabordare (several resonances correctable in part only moving the diffusers from the wall of bottom for "equalizzare")
3) Dynamics and impact scarsettini
4) small Image in the three dimensions, breakup much compact one, that is instruments "piles up" and small to you

You will say: accidenti!!Quante storie!!E' a disastro!Invece not, this my appraisal is been born from the pitiless comparison with my mental standard that I had fixed, characterized in Aura CD-C50, than under all the parameters cost was much best (4X but!!) and therefore improponibile... But unfortunately, once that us one is accustoms you to a standard is difficult is made to be enough something of inferior then. JVC XL-CZ 232 of factory (PEM of 3° generation), like that one then PEM of 2° generazione), even if improved, creed, making a comparison to little reliable memory.... is however preferibile to many concurrent of the same one wrap of price, but attention to otherwise insert it in a system of quality and with one perfect synergy....... disastro!!!!! Even if with little deep bottoms, harmonic thoroughness less pushed and a sure one roll off up, the musicalità is remarkablly meglio.Ma with some recordings lacks qualcosa.Può that it is also a issue of "like appeals to me the sound", more energetic and to be detailed, while to someone it even goes well therefore. But creed that for to be godibile the sonorous message must capture the attention and unnoticed (never is capitato to you to listen to the same disc with different apparatuses, while you are even occupied to make qualcos' altro??L' every apparatus "better" as well as distracts to you why it produces a sound, a particular one that unnoticed, and from creed the fluidity and facility of I listen here, "it do not have to listen in order to feel but more rather to feel details and particular spontaneously without having itself to engage too much to pick up them in how much exit alone". As usual it is said, improving feeding, mechanics, section of escape and several electromagnetic interferences, gaps of the economic readers, would have to be obtained improvements. And it is what I have made.

MECHANICS:

Substitution of the platorello premidisco in steel with one in light plastic sagomato in order to couple it to the hinge premidisco (black). b)centratura of the magnet to ring shape contained in the hinge premidisco, that I have observed, in phase of spin, has a game Pò. In order to center it, applied on the external circumference of the magnetic ring, after to have removed it from its center, a layer of adhesive tape not too much often, finchè does not catch up the just thickness in order to fit perfectly in its center. These 2 operations will avoid sfarfallio of the disc in phase of reading, having lowered the barycentre of the hinge on which wheel the cd, therefore little vibrations and resonances x the laser.
Output Filter Section:

Substitution of dual operational amplifier jrc4580D with the Burr-Brown opa2604. Without hoof (I have knit direttamente)ma are sonically unexceptionable members and therefore I have not risked to having to replace them several times with others in order to find one adapted. But if you have this intention used one hoof.
1. Substitution of all the yellow condensers places after the converter and before op-amp with others of the equal characteristics electrical workers but to the polistirolo.
   N.B: those that I have put are 4, grigini, but I do not know any marks it, in how much it is not printed publication over and however they are economicissimi.Al care I can advise who has intention to replace them to make of the tests, like I have made I: decided to risk an unfruitful operation, I have replaced them, and after I listen immediately after this modification fortunately I have stated that they have improved the extension up, the detail, what that me has been useful, therefore I have leaves them you. But if those that you will try sonically turned out inadequate you will have to remove them and to try again completely without information with altri.Sono however convinced that if a substitution "to case" as that one made from me has improved the things, sure those of series are insufficient and therefore whichever other discreet thing you put to us will go well. If of found of quality much best
2. sostituzione of the two Elna condensers from 50 v/47yf places between op-amp and the escape with two from 16v/100yf MUSE Nichicon I had to hand capacity these, but others not elettrolitici (coal polypropylene, paste, paper and olio)andranno senz' other best
3. sostituzione of the two condensers elna remaining on the distance of marks them with two condensers to polypropylene ATD from 400v/4.7yf
4. bypass of the circuit of dumb after the aforesaid condensers, that is to the escape of same x the every channel I have connected a cable shielded with stocking with 1 conductor of 0,25 of sezione.La stocking then is knit to mass on the print on one side and from the other to the mass of the rca of escape (you remove the black block with the 2 rca originates them from the card and sostituiteli with plated connectors of good quality). All that cause you do not damn, only a click to the accensione/spegnimento of the apparatus, ovviabile, also in order not to damage accidentally the others members connect to you, igniting only widen it after to have ignited the cd.

    

   AGAINST The MAGNETIC FIELDS:

   Positioning of barrette of ferrite (enough opening the rings with closing to hinge that are bought in the electronics storees: to the inside there are 2 barrette, enough to remove le)sopra the local p0wer source, around the digital cable them to piattina under the mechanics (it is nascos to and it slides together to the laser, enough glue them with the biadhesive one so that its estensione/avvolgimento) and the other to flank do not hinder, around the quartz and to the members close to it that they generate the clock, and in order to end one of those "coccinelle" that they sell x to absorb the cancellations for cellular that for its small dimensions and the biadhesive one on one side can very well be attacked on the support of the laser where the laser/segnale conversion digita them happens.

   

    

   FEEDING:

   Substitution of the feeding cable standard with the MERLINO cd This modification is made for last, single after to have estimated the improvements on the machine it brings to you from the other modifications for sure being that they did not depend prevalen fearing from the feeding cable.

   N.B: Every modification I have made a test of I listen in order to see how much influenced every small detail to totally compose the sound of a cdp. And I assure to you, nearly every modification has turned out to have its, seppur to times small but obvious effect. They are convinced of having resolved great part of the defects of the apparatus, those defects that probably do not make to second prefer it (twisted me however to) to other models of the same one wrap of price. Who has the courage to make it (knows someone that is still trying the data electrical workers on the feeding) can replace the surdimensionato local p0wer source with a toroidal one, lodging it in the left part of the apparatus, completely empty, removing therefore all from the analog and digital circuits .Sicuramente it will give bonds turns out to you, but currently me enough wide the caught up result, than, I think optimal (for me). Moreover, this plan has not been cured to the esasperazione, many members me was already available, but if cure will be had to make several tests (that I have not made) and if members use themselves more select to you, sure the maximum is obtained.

   TEST Of I LISTEN:

   Used discs:
   to part my personal that I know well, Tracy Chapman - Tracy Chapman, Sarah J.Morris-Blue Being worth some, Bjork-Gling Glò, several Audiorecords, Completed Demonstration Disk Chesky, Audio Top several Selection, Mighty Sam McClain-Give it up to love, Ana Caram- Bluebossa, Sheffield/XLO test & Burn-in CD.
   Chain of I listen: Aura VA-C100 Evolution II with cable widens alimentaz. TnT TTS, diffusers Chario Syntar 100 from pavement, cables of marks them G&tBl and power Monster Cable.

   Regarding the cdp it originates them hour are improves all the parameters to you: they are increased considerable the macro/micro dynamics and the immanenza of the percussions above all after the feeding cable, while the substitution of the escape members has given a discreet but not eclatante result until the bypass of the section of dumb, that it has freed the sound from a veil on all the phantom and from a microcontrast a Pò sacrificato.Ma is above all the image that has had benefit from all these modifications, and hour is the much widest one than like I have not never felt to house mia.Un aspect to it that he has hit to me particularly has been the passing of sibilanti on the high ones, with united one better extension!!
   The applauses, beast of all the systems, FINALLY seem little mixed frittura, truer. Also all the ferrite posizionata to the inside has given endured the impression of a cleaner, limpid sound and of one better resolution. The defects of timbrica nature, lack of weight, mean low high veiled, are passings in great part, and hour indeed they are satisfied.
   Council these modifications to who has wants to attempt in the not expeditious (temporarily) task to make them, a lot in order not to find again itself with a Hi-end monster, WHAT THAT NOT SUCCEDERA' OF SURE!!, how much for divertimento and however will be able to enjoy a sound that probably would demand one spold remarkablly advanced.
