Pavel and I disagree on many things. But, I have also learnt a lot from him. Keep an open mind. 😉

Yes, ad825 in I/V and opa627 in other circuits. ad825 give some "brightness" for sound.Anyway it is just matter of personal taste,not a general rule.In my Rotel right now all opa's is opa627.

This is no surprize at all.
The source is the most important component on any system.
Improve the source component, and everything improves.
Always have this in mind.😉
anyone know some good audio opamps from analog devices?
I'l be sampeling for my amp's which is altso a school project, so asking samples is, at least according to myself, a totally acceptable way of sourcing components.
(just a litle disclaimer offcource
)
any other companys to reccomend that gives samples?
thanks,
Marius

ad825,826,8610,8620 can be used as audio opas and sounds good.ad825 and ad8610 single,826 and 8620 dual opas.Important for 8610 and 8620 power voltage must be not over +- 13v.ad797 very good for pre-amps because of extra low noise,but for my taste ad797 have a bit "sterile"sound.

Have you expirience with this chips? I looked in datasheet,the are very good,but they basically created as video amplifiers and can oscillate very easy.If you have opportunity to listen this chips,please decribe your expirience.
as analog devices only offer thre sample types, i would like to make them count.
a datasheet is a datasheet, but can anyone tell me which is the best of the ones reccomended?
a friend of mine got some ad797, but we havn't tested them yet.

It's not really important what the first link in the chain is, but rather what is the weakest link. In practise this usually means the most important components are the loudspeakers and the acoustical properties of the listening room.carlosfm said:

So you think you can put a bad CDP sounding good just by connecting it to a good amp and speakers?
No way.
You would be surprized to listen to what a pair of 200€ speakers, a half decent amp and a good CDP could do.
Invert the situation and it's misery.
Failing to understand this is going around in circles, changing cables because the sound is harsh or undynamic, a never ending story that some "audiophiles" get trapped into.
If the source doesn't sound right, everything gets mudded in such a way that there is no miracle that can cure it.
Invest the most on the source, it pays.
Otherwise, you can't even test an amp or a pair of speakers.
I've heard very good $peakers sounding very bad with cheap CDPs, there is nothing you can do about that.
You can open the CDP and do some serious work, of course.😀
No way indeed. You and AnthonyAsh need to read my post more closely...carlosfm said:
It's obvious that garbage in means garbage out, but in the average stereo it is the speaker and the roominteraction the screws up the sound the most! 🙂
That's the place where the big improvements can be made. The differences between budget and really good cdp's aren't nearly as large as the differences between budget speakers and high performance speakers. And that's not even taking the room into the equation. If you have a bad room, you can fill it up with million's worth of highend, even mod the hell out of it 😉, and still not get decent sound.
Heh. Well, the source is a link in the chain, and if it's weak the system will sound poor. Just as if room acoustics are poor it'll sound poor. But it's a different kind of poor. All links are important, they just cause different weaknesses.
Why not take the line "if the amp(s) are poor nothing else can make up for it"? It's all the same really!
I think Carlos' reasonining is that you should start with the source end in order to more clearly hear what the others 'links' are doing and are capable of. This is a good approach for considering a system and how it might be improved I believe.
I'm probably not making any sense, so I'll just get back to work

The differences can be as large as that, IF you care to listen before you buy.
Expensive doesn't automatically mean good, but there are some few examples that can really make a whole of a difference.
Night and day.
Of course, we are diyers and what we love to do is to take a "normal" CDP to perform as good as possible, instead of spending big $$$$$.😉

That's right.
It doesn't make sense to invest on a system with a cheap record player with a plastic arm as the main source component.
In this case, spending money on the other components first is like starting to build a house by the roof.
The amp will sound bad, the speakers will sound bad, you will be very uncertain about your choices.
Of course a pair of speakers must be chosen having in mind the room where they will be used.
This means small rooms, small speakers, big rooms big speakers.
It doesn't necessarily mean you have to spend big money, you just have to match them.
Big speakers, as expensive as they may be, sound horrible in small spaces.
Heck, I payed 250€ for my Epos ES11 speakers and i don't want anything else on my main system.
I bought them used, 5 years ago.
But I've heard them on my room, before buying. Not everyone can do this, but I can.
I don't buy anything for my system before trying at home.
I have my contacts...😀
