For the laptop you need a PC Express Card slot (and nothing like PCIExpress !!).

This is a bit confusing to me: Does it mean one would need an Express Card sound card? (e.g. like Indigo? http://www.echoaudio.com/Products/ExpressCard/IndigoIOx/index.php)

And for PC is a special PCI card required or is that supplied with DAC?

...Like you said the 384 sounded amazingly much better, it was more like wanting to listen more and more....The next song was 192 and that was a step back.

So it looks to me we need more 384 music plus the NOS1!

Really? But was this a comparison of same recording at different resolution (384 vs. 192)?

Otherwise it's a comparison between apples and oranges...
-I guess the 384 is from 2L (Norwegian purist record company with SOTA equipment) and the 192 was "something else".

----------

I have Ray Brown/Soular Enery in 24/192. It's an analouge recording from 1987, sounding "very good". I ripped it from a DVD-A.
But Diana Krall/The Girl In The Other Room, from 2004 sounds in many ways much better in 24/96 (Ripped from the DVD side of a DualDisc).
What does it say about the medium (96 vs 192)? Nothing!
-It only tells me that the latter title has a better recording and mixing.

Pls correct me if I am wrong.

Hey Josef,

All what you need comes along with the DAC. No soundcard or anything needed. But :
PC needs a PCIe x1 slot (this is that very small slot).
Notebook needs a PC Express Card slot (or adapter to that).

Ed, before I forget, thanks for posting those nice pictures. Very nice to meet you and your friend, and now I at last can differentiate you from your brother over in the US. About that, I'm always the most confused, you talking english sometimes, Frank talking dutch where he can. But now I'll know forever who is who.
This confusement started right away when you both signed up for XXHighEnd, because indeed you both did that on about the same day. What I never knew though, is that you both did that without knowing it from eachother (as you told me).
Twins ? haha

And GerardA ... similarly the same counts here too, just because of two Gerard's being here, while both you and our other Gerard were there. Very nice talking to you, and I must say, time was too short or didn't permit extensive talking.

What I learned from it (but also hoped in advance) is that such a "being together" is a kind of priceless. I mean, at talking to eachother, helping eachother, creating something together for already quite some years now, it is so nice to see some faces behind this and talk to eachother in person. And never forget, you are indeed helping me and everyone, me coincidentally doing the coding here and there.

I think we should arrange for some more of this, and then indeed in a well prepared fashion. It can be just about listening to music, but merely a showoff of how things really can be. Just for a reference and what can be achieved. Bert and I talked about this a while back already (that we both will arrange for this), and this "session" came in between as something which looked like an opportunity. Well ... haha;

I'm sure that many of you ever visited Bert's place and left there with a WOW, while quite as many ending up with a pair of his speakers. I can assure you once more, this hasn't changed, but the conditions must be there to do it. For those who vistited my place (not so many) the same WOW was there. Different speakers but also from Bert, this time combined with some DAC from my hand.
You will see both types of combination in the future, and although the last this post is meant for is to be commercial, it will show you how far we are with audio, and that it is something different from what you know. That *is* a promise.

Of course there is the problem "where to do it", and while Bert's place is too small and I theoretically have the space to house some 10 or a few more visitors at a time, I'd still have to arrange for a comfortable listening place for that many. The options are sufficiently enough there though, and maybe always better than dragging the lot to some hotel room where it *still* all may not workout.
For those who visited me ... there was my living/listening room which will not be comfortable enough for 10 or more people (although they will easily fit there), but there's some 300m2 space in the basement (generally 3 areas of 14 x 6 meters) and there's also an upstairs space of again 14 x 6. So, maybe we go as far as decorating one of these spaces for audio and just as a showcase for how far we are and have some nice meets in the mean time. We'll see.

Lastly, and this may be a kind of commercial talk indeed ... supposed such a set brings you this WOW and you are unsure whether you can create it the same in your home, it always has been my idea to kind of guarantee it will workout (if the room allows for it to begin with, which in normal cases always is so, of course). I mean, the whole lot you will be listening to is from our own hands from start to finish. This is software, D/A converter, amplifiers, speakers (the latter varying from horns via normal to open baffle). So, this will be quite a unique "guarantee" of which you can be 100% sure all matches and should be able to sound the same at your home. It then has become unimportant whether you actually like tubes, because when you say WOW to this, well, who cares.

By the time this really happens I better quit one of my of my other jobs ... Happy
Peter

@ pedal, you are right, I would say this too if I had not been there.
But I'm a bit hesitant to say too much about it, for me the 386 reminds me of the best I ever heard from analogue and then with better definition, less distortion etc.
It sounded 'natural'. Then the problem is we still are stuck with 44. So what to say about that?
For fun I've been listening to FM-radio all day today and that now sounds like the AM sounded long time ago.
But it was possible to listen all day. But it is so clear how much worse it is then what we're talking about here.
I hope that after getting used to 386 it is still possible and enjoyable to listen to 44.
Maybe you think this is a bit over the top but this is always a consequence of improvement.
A lot of people are happy with a decent hifi but if you're used to something better you have a problem when you have to go back..

@Peter, this sounds very interesting! I hope you can make it happen. Maybe it will be difficult to maintain but a few sessions could be a good try.
And I could not hear if your DAC is the best in Amersfoort, but if it is, I'm sure there will be a lot of interest from all over the world to come and listen!

BTW, if those woofers are very sensitive , like more then 95 dB, I guess 27 Watt is enough.
But if not then it's like for the control you need a low output impedance, so low impedance Power supply with a lot of current.
Then for a constant voltage you get more amperes, so more watts.
Two woofers in parallel (series is not good!) then the impedance is even lower, together with impedance dips and lower dynamic impedance the
27 Watts at 8 ohm, have to be 54 at 4 ohm, 108 at 2 and 216 at 1 ohm. But maybe those Beyma's have a high impedance, I did not check that.
I never tried to check if it's through, but this is what I remember from theory.

GerardA

BTW I always wondered what job you can do next to XX because it must take up most of your time!
