seminarian nice review and congrats on your new Dac! I've read some reviews on the Sw1x Dacs their philosophy is very akin to Audio Note which is the Dac I have. There is a lengthy thread about Sw1x started by a member here named wig, check it out:
I can try a comparison but it is difficult because the two units are in two distinct setups. The SW1X is fronting a 300b tube amp and the Yggy is fronting a Pass First Watt J2. The speakers are both open baffle so at least there's a similarity there. Also, the two systems are in two different parts of the country. So I can't compare them at the moment.
But I will say this. The Yggy is very good but it bears a strong family resemblance to everything I've ever had. I think the biggest change going to the SW1X is that with it there is no end to the size of sound trying to get out through the speakers. As I mentioned all other DACs just turn to chaotic noise if the amount of (volume, complexity etc.) music being shoved through the system is too much. With the SW1X, it can handle anything and everything. Which translates to musicality. And as you shrink the stage, volume, complexity down it just reaps a corresponding benefit. This by the way was true even with some miniscule Klipsch book shelf speakers that I had before I got my big open baffles up.
I also think the low level detail really amounts to the sound of the hall itself and not merely hearing the musicians better. The SW1X is great at conveying a place (and people) not just music. The Yggy was okay in that regard but not startling.
In my review I noted that the SW1X is not my first R2R DAC. I've discovered that there is more to the issue than R2R versus bit-stream, as if one is automatically going to emerge the clear winner. What I didn't get into much at all in my review is the true reason behind why the SW1X stands apart. It's not merely the R2R design. It is more a matter of the implementation of the circuits as well as the materials science involved. R2R doesn't automatically change much. Non-oversampling doesn't even automatically guarantee success (as was the case of the Altmann, it didn't separate itself all that much).
Check out the SW1X website and start reading. I came away convinced that I needed to try Slawa's designs. I'm glad I did.
I did check out the very interesting SW1X website last night.I read the *Audio Hell* article last night.I'll go back and try to learn more about the actual design and implementation.One thing pointed out in the article that made me stop and think was not to rely heavily on your favorite tracks when auditioning a new component.The biases that people have can result in repeatedly choosing components that sound like you *want* those favorite tracks to sound like.
I know exactly what you mean about complex music turning into a congested mess.The dac I was auditioning last month did just that,so back it goes.
