Good to know. A work around might be to upsample everything with HQPlayer to the same sampling rate, which is what I'm planning to do.
This is not a solution. I am using HQPlayer to the same sampling rate, the problem is when I change to a source file with different sample rate. Probably in this case HQPlayer reset the connection.
I have a few of my PCBs left, both single-ended and balanced/flipflop versions. Send me a PM if you're interested.

i assume that the sound of these noDACs is much better compared to some cheap DSD DAC (or even expensive one for that matter)?
in the beginning Hazard was saying there was no bass, ist that fixed now?
i am apologizing for my ignorance, but how exactly is this PCB to be implemented, connected with the Lundahl? i am planning to use the i2s from an m-audio delta 2496 and connect the output of the noDAC to the MCA by Mark Houston. is this possible?

I've received your PM, thanks.
I think you need to understand this topic a bit better before going too much further or you will end up disappointed.
Your m-audio board doesn't support DSD so it is a non-starter for a project like this.
Hazard resolved his bass issue a long time ago, as was described early in the thread.
The PCBs I made are designed to piggy-back onto the JLSounds I2Sover USB board. The balanced board uses a flipflop device to derive a differential output signal - this is the approach Hazard uses. The single-ended board outputs, unsurprisingly, a single ended output signal that is of a lower level (also has significant DC offset so requires a capacitor on its output).

thank you both for the replies, is there a PCI card in existence that supports a RAW DSD output? and if so, is it possible to use the noDAC boards together with it?
You know, you just did suggest me an idea:
to find a raw dsd PCI-express board.
It would be a very interesting idea, because the standard here are the usb i2s/dsd boards, but bypassing the usb interface can't be wrong...
I second you on your request.
Ive not heard of one. Its getting hard to find any hi res PCI cards these days, in the past I've used both MAudio and EMU cards capable of PCM 24bit/192k but I believe that they have been superseded by USB devices. You cant edit DSD files on a PC so no doubt there has been no demand for a DSD card. SACD was a protected format and its only been very recent times that DSD (.dsf or .dff) files have become wudely available.

I think a PCI card (and I'm not sure you'll find a DSD capable one) will be a compromise because of the need for long connections to the DAC, best to keep these signal paths very short.
A USB sound card will work just fine and will be easy to source.
If you want to eliminate USB I suggest the Beaglebone Black/Botic route described on the Twisted Pear forum. I've used this at upto DSD512 with my Buffalo DAC IIIse.

Why not design a PCI card with an integrated noDAC (with tubes). Is this even possible as a community product or would it require a serious engineer to do it?
Does the BBB with Buffalo give a sound more true to the original recording than the USB noDAC?
It's differente BII or III with BBB processed more the signal so a little bit of loss , noise, etc.
The 'home' environment of a PCi card is a poor environment for analog audio. Add to that the undesirable effects of heat from tubes, plus the need for multiple sources of clean outside power, and you have a project that a serious engineer would shy away from. Especially considering the simplicity and economy of recreating the DSD stream from an asynchronous source like USB or ethernet. ...just my $0.02...
you are right, keep it simple. but if you want to do so (like i did for the past 15years) you simply get stuck sitting on one and the same chair for the rest of your life. in my case it would be listening to mp3s.
making a step by step progress takes a long time to come to the end. why not just make a giant leap from mp3 to the holy grail of audio by combinig digital and analog together. i will start a new thread and please everyone share 2cents or more

Well, good luck with your project.
The obvious question is why? In my opinion your proposal would be significantly compromised compared with, and a lot less flexible than, what can be achieved today with a good USB based solution as outlined in this thread. It's a giant leap when you haven't even heard what a no-DAC can do.
You are absolutely right. Why complicate when it can be so much simpler? Well every time you upgrade your equipment it takes time and money. It is also fun. But if you choose not to go step by step but instead jump right to the best one possible, you never need to upgrade again.
The first 'update'/'upgrade' will be available about 2 days (or less) after the purchase. New options to be installed after 2 weeks, the first 'new' devices to be connected will be there after 2 months, the first incompatible items that must be used will be pushed upon you after 2 quarters, and you are looking at replacing at the end of the first 2 years that you own it. Better hurry and go sit in front of the shop, you can be the first one ...
