Is it possible to build (or get a kit) an IR device that I could use to activate the Otto from a universal remote. To toggle between inputs?
Instead of using a rotary switch.

I have used the kits from http://www.tauntek.com/ I like the fact that you can program the receiver and use any remote of your liking.

I have seen those. How do they work basically? Not the programming but rather how do they switch a device? Do they send a voltage? I can't find any instructions for it.
Thank you
Darren
I only have experience with irvc2 but I think they all work the same. Basically you can assign any output to any key in your remote and outputs can be momentary or toggle (or channel select in the case of irvc) toggle means on-off, momentary means momentary on. On=5v, off=gnd. check out the documentation on irvc2...

Oh, I see. So the pin headers are where you connect wires that you want on or off. This thing is just a fancy switch. Right?
Thanks
Darren
Yeah, just a fancy, remote controlled switch. Perhaps the Uber will have spare pins to switch other things.

Shoot! Im sorry I forgot to ask if there was a limit to the amount of voltage that can be switched and is it only AC. Would be cool to power the whole dac on and off with a remote.

(apologize for getting out of topic)
There is a limit as to how much current those pins can drive. If the thing you are driving sinks more current than what the pin can supply then you will have to build a little circuit called a emitter follower (I think). Basically you will drive the base of a transistor through a resistor (which limits the current) and then drive the thing your are switching with the emitter. I found the circuits on the web but right now don't remember exactly how to do it, but it is a very common approach to drive larger currents. With this approach you can switch any kind of relays for any kind of application.

Just because you are seeing the native sampling rate coming out of your PC doesn't mean Kmixer hasn't damaged the signal.
The test you need to do is to play a DTS encoded wav file into a DTS decoder (home theater receiver.) If you get static you know Kmixer has molested your digital output. If you hear the music/soundtrack you are good.

How can you then prove that once you switch to regular stereo 44.1 kmixer will not do its "thing"?

This test also works with HDCD encoded material provided that you have an HDCD capable decoder. (Unfortunately they aren't that common.)
I have found no instance in my system where kmixer did not corrupt hdcd encoded material.
Well, it should be something you really can hear as well. Typically the image loose focus, the 3D-effect is much less, danymics are less...that is why the initially maybe superior USB-Interface with Windows standrd-drivers may or may not sound really better than SPDIF over KErnel-Streaming or ASIO. That has been my original question: HAs someone with an Opus listened to both variants and can say for sure whichone sounds better ?

I don't know if it helps, but I have a dual-mono Opus with ASRC set to 192k and am using Vista running foobar as source.
I've been using it with the resampler plug-in set to 96k and output through my M-Audio SP/Dif via KS.
I recently did some comparisons with that config and variations on it and with USB via KS and could not hear any audible difference.
I also tried it with the resampler at 48k via USB, but thought it sounded worse. The only drawback I've found is that on USB I get an
occasional hiccup, but usually soon after initial power on, so it might just be something Vista is running in the background.
The sound is excellent through both setups, and I really couldn't pick between them.
(I haven't been able to get the M-Audio ASIO driver to work properly with Vista, - too many clicks and pops!)
Hope that helps. 🙂
Re: Haiku
I suppose you could if you put a series resistance at the DAC output. The resistor would have to be at least 1K. You would also have to change the voltage gain resistors on the Haiku.
I am not sure how it would sound. Might be fun to try. 🙂
Cheers!

WM8741
I received my new version of the Opus a couple of days ago, and here are my initial impressions.
There's no doubt that the WM8741 is quite a step up from the previous one. I was not pleased with the previous Opus version. It sounded mechanical and very tiring. It was no fun at all. And with the metronome it sounded even worse. Noisy as **ell and it gave me a headache after 2 minutes of listening.
The new Opus is very enjoyable. The sound is much more relaxed and flows naturally without any noise. There is a new sense of thereness and realism, which I think is very important. It's now possible to use the Metronome in 192kHz mode without any added distortion. I don't know if it's lower out of band noise, less pre ringing or better jitter rejection that makes it so much better. But it certainly is. Recommended.
I can now throw out my super modded Pioneer cd-player, since the Opus actually is better. And I don't even like the idea of pc based playback in the first place.

I'm glad you are enjoying your new DAC Painkiller.
I'm surprised though that you found the 8740 version so poor though, and I suspect there was a problem. My experience is that both the old and the new Wolfsons are capable of excellent performance, with the new chip a minor upgrade at best.
