Tama din naman yun pero sa akin kasi kaya ko tweak para lumabas yun gusto ko na tunog, pero sa akin lang yun.

Probably, if everybody only knew which parts to replace, or adjust, then everybody would be doing it. Kaso nga madami din na hindi mahilig humawak ng soldring iron.

The point is, not everyone knows how to do it. Example, gusto mo palabasin yun very fine highs (o minsan tawag nila air), pwede yun basta alam lang kung alin ang alin. Kaso nga hindi.  ;D ;D ;D ;D

Syanga pala, kahit papaano naman ay alam ko yun ginagawa ko, walang magic dito mga sirs!  ;D Mahirap na baka dahil sa akin ay may magbukas ng cdp nila at makuryente, walang sisihan! SAFETY FIRST!

lahat ng comments tama, kasi hindi naman pare-pareho ang tenga natin. kanya-kanyang biases, even adjustments, sa hearing. ang maganda naman sa tweaking, especially if you have same models as reference, you could do an A/B comparison ng modified and non-modified units. then you decide, which comes closest to your personal preference. malay natin, baka mas maganda yung original configuration since it was already optimized. pero that could apply to one listener, the other might choose the modified unit. it's always relative, and it would be difficult for one to say who's right and who's wrong.

Agreed, that's why other's try to audition first para malaman kung ok sa ears yun sound. I recon everyone to be right.  ;D

Guys,

Tweaking and DYI-ing for some of us is not simply to be able to change the sound characteristics of our CDPs.

For me there are several reasons why we do this, like being able to learn how our system works. For us na hindi nakatapos or nakapag aral man lang ng basic electornics its is a new learning experience, kahit na risky and magastos minsan. Biruin mo bagong-bago na RCD02 bubuksan at kakalikutin.

Next is that we devived fulfillment in what we do, knowing that we do not have adequate skills or knowledge, but we could still do these changes to how our system and often it works. For us the effort is as fun as listening to the results of our work. So please do not spoil our fun.

Moreover, we try to be carefull din naman, unlike what some are implying. We try to learn as much as we can by asking knowledgable people, reading DIY treads, reading and learnng component specifications, trying to understand as much as we can about our system, so that we minimize the trouble and risk. To Jojo, we may lack knowledge and skills like what you have but we're not stupid din naman. Jojo, I know you are very very good with these things, kaya nga kami nagtatanong sa iyo eh. But please don't push your weight around.

Kung alam na namin ang magiging output ng gagawin namin, where is the fun, anticipation and excitement in that. On the other hand kung kasing galing na namin ang iba sa inyo sa circuits and electronic components we would not be doing tweaks to our CDPs anymore but instead designing and creating circuits for preamplifiers and gainclones.

Some of you would say that one needs to understand the whole circuit and how it was implemented and what parts only needs to be replaced. Point taken, kaya nga sabi nababasa at nagtatanong din naman kami. Pero tanong lang kung many of us aleary heard a 02 and 971 in a shootout before? Even if we have knowledge of the circuits and replace everything with optimum components would we be able to know 101% if the 02 would eventually beat the 971 or even the 1072? Who is willing to bet on that. Again, it is not just the knowing of circuits and components guys.

Still some would say, why do we do this with our CDPs since they are optimized na for best performance. Well, all I can say is so what? I do not comment why some of people would insist on buying surplus and pushing them against newer CDPs and trying to make us feel so sorry for spending so much time and investment with our gears, when we know people who do this are very much financially capable naman. I don't care kung mas trip nyo ang surplus, eh or ayaw nyo humawak ng soldering iron. Kanya kanyang trip lang yan.   

Another, we all know this is partly a social thing. Being able to share knowledge based on experience, being able to meet new friends and be together in session is also another reason. To meet people with the same interest as ours is very nice for everyone.

Kaya sana walang siraan ng trip ng iba.

Kaya nga ako umalis ng Wiredstate eh, hirap makipag usap sa mga mayaman at mayabang.


Yun lang.

Pasensya na po.

Nung una kasi I thought this would be simply sharing of ideas, experience, and advices. I did not think this thread would become somewhat like a measurement of technical knowledge and skills, and probe on the actions and decision one has done on their audio gears.

Nakasama lang ng loob.

I will cop out and not choose sides in the debate, if there is a debate. Having urged a lot of people to do part upgrades on their CDPs and amps, I feel I should say something about the issue. I admit I hardly know anything about electronics--I am in fact a business graduate with a day job as a researcher. My first exposure to electronics is in August last year when I tried to DIY gainclones.

I fully agree with Jojo that we should try to learn the circuit first and likewise with Kimpao that we should first identify areas where tweaking could bring noticeable changes. For me that's the ideal. I'd do that if I could but I don't have a background in electronics. I read and try to learn as much but not having the foundation of someone who has gone through a 4-year electronics course (or 5,6..) in college, I'm hard pressed to understand circuits.

So why even attempt to do it? It's been said before: some of you think that the circuit is a distillation of the engineer's knowledge and experience. How can a business graduate like me improve on a design collaborated on by experienced engineers? That's one way to look at it. Although not entirely contradictory, one other way to look at it is that enginneers and their companies are subject to the economics of competition (and you don't need to be a CFA or CPA to know this is true). That said, there's a strong argument that they would use the cheapest acceptable components in their circuits to be able to sell their products at a price that would attract a bigger audience. Sorry if this is beginning to sound like Marketing 101 but this is central to my reasoning behind part upgrades.

And when I look at the innards of my CDP, I can see where engineers have CONCEIVABLY cut corners:

1) Using transistors for muting instead of relays such as commonly found in higher end CDPS
2) Mylar instead of polystyrene in the LPF stage
3) Ordinary grade electrolytics vs. low impedance types that have better HF filtering
4) ordinary rectifier diodes vs. the supposedly quieter soft/ultrafast recovery types
5) Legacy opamps vs. newer ones that on paper at least looks superior to the one you have

So I upgrade parts when 1) Someone says that a part improved his CDP/AMP by changing a part or adding a mod; 2) The part is readily available and relatively cheap; and 3) I can do it myself. Whether the tweak/MOD will work for you is something you have to decide for yourself.

My biggest advantage and disadvantage of not being an electronics expert is that I don't have preconceived notions of what works and what doesn't. If someone's got an idea for a tweak or mod and its within my means, I try it myself. I don't need to understand the circuit just the general idea.

Bogsle,

You may have misunderstood my post  ;D, I'm not pushing my weight around (literally), please don't look at it liike that, it is suppose to be a learning hobby for all of us and it doesn't matter how much knowledge you or I have, we both learn here.

If there is anything that I would be pushing, it certaincly won't be any of you guys here, it would be the electrons.  ;)

Ganito rin ang impression ko nuon, but this is not true. Most people there just want to share their experiences and all one has to do is choose the right thread. I specifically like Wiredstate's software discussion forums, walang away, puro reminiscing and appreciating beautiful music, hindi nga lang ako maka-tiyempo ng mahilig sa classical.

WOW haba na ng thread! Sir Bogsle medyo madamdamin 'yung post mo hehehe. One thing i've noticed with this group matindi asaran pero pag nagkita-kita okey naman! GULAMAN LANG KATAPAT NYAN!!!!!!!

Back to CD player,  I agree with Sir Garp SOMETIMES you really don't need to fully understand the design of the circuits just to make a tweak? Replacing 47,000MF Raon capacitors to ELNA type can do some tricks? We all know that we are all using highly commerciallized Brand CD players so we can expect cheap parts in our players. Let me explain my  own experience, Shanling CD-S100, USHER CD-100 & Music Hall MMF-25 CD players have the same circuits, Features & even the looks. Price are arranged from lowest to expensive. Do they sounds the same? Nop, if you can take a look inside  they have the same value but different brand components.

In General there are two types of tweaking "One is Modification" This requires Expertise"  & The other is "Plug & Play"  for everybody. Somebody from the group have expertise in electronics some have fair enough money to buy high-end gears, for me my  purpose of attending listening sessions are meeting people who have the same interest & Learning, which is not enough but the best of all is....FRIENDSHIP!!!!!!!!!
FISH TO EVERYBODY!!!!!!!
