bhobba Posted May 25, 2018 Share Posted May 25, 2018 I am trying out some of these settings to see what is the best and decided to give converting to DSD a go. I have a PS Audio Direct Stream. When I select auto detect DSD the DSD grays out as an option to send to the DS. If I select send packed as USB 1.0 or USB 1.1 you get the option, but it doesn’t work - instead the DAC says PCM 176 and nothing comes out. On the DS forum they say go to the Audirvana forum - isn't that just maddening. Who knows whats going on but if you ask the DAC maker - its Audirvana's fault. Hopefully here wont do - its your fault - no its your fault type rubbish. One even said - download the Windows drivers ? Any ideas? Thanks Bill Link to comment

The DAC displays PCM 176 and at 100% volume you get a very low level very highly distorted sound - but at normal volume level you get nothing. Thanks Bill Link to comment

Since it was displaying PCM 176 I sort of figured that. I think some kind of control information is being mucked up somehow - I suspect the DAC is not recognizing it from Audirvana. But since others have got it working - see post Bybuonassi something is wrong with somewhere. There are a number of posinilities 1. I haven't upgraded to Redcloud yet - need to put into a Redcloud machine. 2. Try it into another DAC that does DSD and see what happens. 3. Report it as an official fault to PS audio and see what they say. Why does it have to be this hard? Anyway I also have a DS Junior but its down at my dealers right now - will see how that goes.

buonassi Posted December 11, 2018 Author Share Posted December 11, 2018 any new comments on Sox vs iZotope sonic characteristics? I've recently gotten back into upsampling and have decided to give linear phase / fast rolloff a good month of listening before switching back to NOS/Min phase options. I like both Sox and iZotope for different reasons, and not really sure one algorithm is better than another - they both perform interpolation well. I wonder if @mansr would be willing to do some measurements for similar settings of these two converters? Bandpass and transition zoom FR I'm not that interested in. And since we'd keep it linear phase, no sense in measuring that. But, which yields the lowest distortion: Harmonic, odd order, IMD. Link to comment

Since you're not interested in frequency response, that leaves nothing to analyse. Link to comment
buonassi Posted December 13, 2018 Author Share Posted December 13, 2018 Sorry, what I meant was I wasn't interested in seeing the FR as an indicator of bandpass response (IE any ripple) or how sharply it rolls off (transition). That's what I meant. Should've been more explicit. I am of course interested in how the low level distortion measures in the frequency domain. Or are you saying there's none of that that can be attributed to the FIR filter? Link to comment

The frequency response, which is the Fourier transform of the impulse response, says all there is to know. buonassi 1 Link to comment
Endoxx Omega Posted December 27, 2018 Share Posted December 27, 2018 Hi all, it’s a long time ago I posted on the forum. I was mainly improving the hardware of my music system and now that I have done that it’s time to work on the software again. I love A+ and look forward to the new release. I’m still using A+ 3.2.14 with OS X El Capitan (10.11.6) and thus can use direct mode without changing the OS. I wonder if I should upgrade the OS at the expense of not using direct mode anymore (I will not jailbreak the OS). Does direct mode still make a remarkable difference? Is a newer OS necessary for security reasons or can I just keep on using it? I mainly use the MBP for my music, emails and internet. Thanks for your response. Wim Kind regards/met vriendelijke groeten, Wim Link to comment
buonassi Posted December 29, 2018 Author Share Posted December 29, 2018 the 'hack' doesn't jailbreak the OS - and it is a reversible hack. Actually, it self corrects with each iterative OS update you do. The only threat is if you use a audio settings kext file that is corrupt. You can copy your current el capitan kext file and use it (knowing it's not laden with malware) when you perform the hack. It took me about 25 minutes to do and wasn't really difficult. And, yes, I believe the direct mode is worth it if you plan on transporting via USB to a bridge converter or a DAC. Of course, just my opinion. I haven't updated my mac in over a year because I enjoy the sound so much after achieving direct mode. In terms of consequences of not updating you OS? I'm not sure if el capitan is still supported - probably not. There's probably not a lot of active development for patching exploits caused by holes in other software that resides on the machine.

Thank you Buonassi. I recently switched from Toslink to a Berkeley Audio Design USB converter and I’m very happy with the sound. I will experiment a bit further with the USB and AES-EBU cables but even with the cheap cables I use now it’s already a huge improvement. It gave me the same experience of improvement as when I changed to Crystalspeak Reference Diamond cables for the speakers. I just don’t know how much direct mode/El Capitan adds to that experience. Apple isn’t forcing me to update El Capitan yet. I assume that if there’s a major leakage they would? Any other experiences from forum members?

AudioDoctor Posted December 30, 2018 Share Posted December 30, 2018 I don't think there is anything wrong with keeping your machine on El Capitan if you use it only for music... However, if you use it for other things then I would definitely upgrade the OS to High Sierra rather than Mojave at this point for the security. The hack is super simple and as mentioned above, reversible. In my experience it makes a significant positive difference in the sound quality. buonassi 1 No electron left behind. Link to comment

So unfortunately EL Capitan is not supported anymore. 8 hours ago, AudioDoctor said: However, if you use it for other things then I would definitely upgrade the OS to High Sierra rather than Mojave at this point for the security. The hack is super simple and as mentioned above, reversible. In my experience it makes a significant positive difference in the sound quality. I think you are right that I have to upgrade. Why High Sierra and not Mojave? I will need to find out first how to do the hack if it makes such significant positive difference. I don’t like doing that though since (i) Apple didn’t close that access for nothing I assume, so malware may take advantage of that hack too and (ii) I’m afraid of messing up with my system. But the significantly better sound is tempting. Kind regards/met vriendelijke groeten, Wim Link to comment
AudioDoctor Posted December 30, 2018 Share Posted December 30, 2018 High Sierra has the bugs worked out, Mojave is still maturing, that's the only reason. The hack, done correctly, does not nor can it be used to, create a vector for malware. All you are doing is replacing one apple kext with another apple kext. Read the directions, read them again, and follow them exactly. No electron left behind. Link to comment
buonassi Posted December 31, 2018 Author Share Posted December 31, 2018 Search for content posted by @RunHomeSlow . He has by far the most experience and awesome detail outlining how to do direct mode hack Actually I have invoked his name many times now and hate to keep bothering him. If he can supply the link to the instructions I’ll make sure to bookmark it this time I promise Link to comment
