It works with ASIO though.  Is there a way for ASIO in Foobar to demand exclusive access and lock out other programs?

 

Both ASIO and WASAPI work perfectly for me via Foobar. I have WASAPI with exclusive mode enabled; unfortunately, I don't think ASIO has exclusive access. My system sounds manage to come through during playback. I use WASAPI most of the time, until I want to playback DSD, where I enable RUSB ASIO path via the SACD decoder ASIO proxy. BTW, all Foobar visualizations should go completely cold DSD playback happens correctly.

 

For people that want to play DSD with the Invicta/Mirus/HD/HP/Herus:

The only units that don't work on WASAPI over Foobar for me are C-Media CM6631A-based DAC units, not sure why. They playback 16/44.1, but don't play anything higher. ASIO works for all sample rates and bit-depths, though. (Anyway, off-topic, but just an interesting note)

Thanks for the pdf link.  I tried setting up DSD yesterday with some Google searching but couldn't get it to work as I appeared to be missing a .dll.  That dll's not mentioned in the pdf you linked but I see reference to the DoP marker instead, which I didn't try.   I may try it again later, but DXD is just a WAV file and works perfectly with no messing around.  Is there any reason to select DSD in preference to DXD?  I like simplicity. :regular_smile :

That's strange. All I did was download and install the plugin, no extra DLLs necessary.

 

AFAIK there's a larger selection of music in DFF form than DXD WAV (basically just 24/352.8 PCM). DSD64 files are smaller than DXD, though DSD128 files should be similar in size. Frankly, I'm not really on the DSD boat yet. I buy 24/96 or 24/192 PCM FLAC, and that's about it. I'm just glad the option is there for me to use DSD/DXD.

Quick update on the muting issue.  I'm now using an old test CD on the Oppo to burn in a new headphone cable and the light does indeed go red for a moment every time the track repeats itself.

Sorry, not sure what that means or whether it is unusual. If you play a CD, Oppo to Concero, does the light turn red at the end of the disc? Some music players disconnect at the end of an album/playlist (e.g., Decibel) and some do not (e.g., Pure Music). I don't know what is normal behavior for the Oppo. However, you should not be getting muting or losing lock in between tracks.

No, it doesn't go red when playing tracks in sequence from a CD, but it does if I skip tracks or put a track on repeat.  It doesn't go red when the album finishes, but if I fast forward through a song I get a flashing red light.  With memory stick play it goes red between tracks, when I skip tracks or when I fast forward through them.  It doesn't go red when I stop playback.

I'm testing Foobar again, and I'm getting fade in issues when switching between different bit rates over USB, with the light going red in between.  Track skipping between files of the same bit rate or using track repeat is fine on USB and the display stays blue.  This is a bit of a show-stopper as I can't miss the first second or two of most of my songs!

Sorry, but I am not being much help. Have you tried contacting Resonessence? They should be able to work you through this. You need to determine if the problem is with the Concero or somewhere else (obvious, I know). All I can say is that I have never observed behavior like this, my Concero has been flawless no matter what I have thrown at it. BTW, I am using a Mac.

I remember getting audio dropouts with the Audiolab M-DAC on Foobar till I lowered the buffer to 100ms which seem counter intuitive, but using a large buffer only made it worse. I have always used a buffer of 100ms since then without any skips or dropouts. The Audiolab M-DAC had a nice feature where you could view the audio buffer via USB on the OLED display. At one stage I had severe issues with M-DAC and Mac OS X, but that was sorted with a firmware update and an OS update. My Concero has been rock solid since day one.

I just noticed you and I have the exact same set up. LOL.

NOT! I like the IIR up sampling filter! :p

post #1407 of 1874

It's not drop-outs I'm hearing, that was resolved by reattaching the cables and twiddling them backwards and forwards (dirty contacts).  This is the Concero fading in whenever it detects a new signal, which means I miss the beginning of every track when feeding it from my Oppo*, and the beginning of the next track when changing bit rate in Foobar.  Obviously it needs to be a track with a leading guitar riff or drum roll, which goes missing.  Switching to a classical piece which has a moment of silence before it starts isn't going to show anything.

 

* when using a usb stick as the source

 

dfuw_concero_hp_2.5.0.exe is the firmware version.

If you select DirectSound output in the Foobar Playback -> Output preferences, what is the fade in and fade out settings there?

post #1409 of 1874

I tried setting those to zero and went back to ASIO, but no joy.  Using DS as the output works okay because everything comes out at the same bit rate, thanks to Windows settings, so the issue doesn't occur (in Foobar).  Leaving it like that I would then have to manually intercede everytime I switched bit rates which isn't an option.

 

As it affects spdif as well I'm sure this is a firmware issue.

I'm interested in the Concero HP as a DAC/Amp combo at work and DAC only at home.

 

I guess this means that trying to compensate for the lack of RCA out by using the 1/4" headphone output is not going to work well since every little SQ gain/lost means a great deal at this price tier/performance level.

 

Can anyone confirm the finding? Any comparison with the HD as a DAC?

 

I don't understand the decision to omit the RCA output on the HP version. Is it due to power constraint? Cost? Product line differentiation?

 

If this thing has RCA out I'd jump on it in a heart beat, but it's hard to stomach the idea of paying $850 for a top-notch DAC, and then can't feed to another amp without degrading the sound quality.
