This thread reminds me of something I have been wondering about
In theory if you run the S/P-DIF connection from the Polar into a high end D/A converter, could it possible that the analogue outs on the D/A converter may sound better than the analogue outs on the Polar itself ??

The S/PDIF is 44.1KHz or 48KHz not sure of the bits, the analog outputs are supposedly 192KHz 24bit and there's many who claim the Virus sounds better from the Analog outputs.

You shouldn't mistaken the Converter specs. with the internaly used sampling rate and bit depth.

The sample rate and bit depth when using Virus Control are exactly the same spec as a VSTi. So there's no reason a TI sounds great but a VSTi sounds thin. Yet I would argue that even in VC mode nothing sounds as good as a TI. If you like that sound then you like that sound. The filter is unique but it could all be emulated as a VSTi. The interesting point for me is that in software anything is possible, but a hardware box seems to have outdone almost everything in pure software.
Does the TI sound better from the 24bit 192KHz analog outputs? Analog not necessarily a good thing because it was digital until the last step. I can't say I have a clear idea and purity of sound surely is not important compared to the character of the sound. The TI can have obvious aliasing but I really don't care - how many times have we seen posts from experts who check the aliasing first and then won't touch anything which doesn't pass that test? They're missing out on a lot of character...

I wouldn't be that hard on the TI, one can get some nice good sounding stuff out of the synth when using the grain tables
Anyway I didn't want to start a discussion about synths quality, even so I know quite some VSTis I'd like to have in hardware. It's rather that the differences between current pro audio DACs are that subtle, that even slight level differences can have a greater influence on the impression.

Well put Summa. I feel those words as being nicely chosen

Are the DACs in hardware digital synths that good? I'd hazard a guess that the DAC itself is OK, but the post DAC analog stage to the output jack is weak - most sound and look from sampling to be a bit high passed. Low frequency waveforms don't have the right shape. And if you look inside the box, there's no audiophile grade shielding and cabling for the critical analog output path.
The question relevant to TI vs VSTi is whether the signal sent through USB to the DAW is lower quality to that sent to the 24bit/192KHz DACs on the TI. If the TI is 24/192 internally throughout, then its a shame to degrade the output by stuffing it into USB Audio.

What synths are you refering to? Lowcuts are typical for Audio-DACs, it's typically not possible to send send DC-Signals trough them. When it comes to the level, if the SNR and bandwidth is fine, I don't mind if the output signal isn't that hot.

Well, major problems would be audiable, noise and interference wise.

It's surely not 192khz, otherwise this would be an option S/P-DIF wise. Wouldn't make much sense anyway, unless one is making music for bats, cats or dogs afaik only the filter calculation would benefit from a sampling rate above 48khz.

I am referring to every digital synth I've owned, about 8 all up. Low cut to reject DC is one thing, but I think it affects the clearly audible low freqeuncies say around 60Hz or higher. Let's just keep it to the TI, it definitely does this. BTW when I suggested the analog stage was weak, I meant it in the sense that it is the weakest quality link, not that the output level was low.

You previously posted that subtle differences in pro audio DACs have audible effects: if synth manufacturers are not treating the post DAC analog stage like pro audio, then its no wonder. Its irrelevant to me (its making its own sounds not reproducing anything) but I thought it was reinforcing your point of view.

Higher than 48KHz would also help in calculating the waveforms - sharp edges and lower aliasing.
I thought we were pretty much in agreement, so I'm not sure why you're trying so hard to disagree with me here.

To me a discussion is not about reaching agreements but to share informations, I'll see to answer the rest later this day.
