A toast to PGGB, a heady brew of math and magic

[SwissBear]

Just wanted to share my appreciation of this technology and of the quality of Zaphod’s support. I asked for a trial licence on Sunday, and was happy to receive it straight away.

 

Zaphod asked about the DAC I had and underlined the fact that the Gustard x26-Pro would be a good candidate to appreciate PGGB. I was sceptical and expected no significant difference between the 16fs capabilities of the x26-Pro compared to the 8fs capabilities of my Singxer SDA-6. I was also expecting that processing files in 24 bits would be enough and that I would not need 32 bits.

 

Zaphod took the time to explain with a great length of details and his genuine skills why I would be better trying 32x16fs and compare with 24x16fs or the like in 8fs with the SDA-6.

 

And as hopeful as I was that I could spare some storage space going for 24x8fs, I have to admit that 32x16fs makes a big difference in the resolution and the airiness of the treble on my system.

 

And PGGB really is a game changer even for “modest” DACs such as the Gustard x26-Pro.

So thank you Zaphod for having brought this technology to us, and thank you for your support.

On checking the official specs of the Gustard A22 - it does not specify 705.6. Only the SMSL VMV D1.

The iFi iDSD sounds great with the 32fs. 

I think I will try 16fs on some similar test tunes and try them out on the Gustard A22. 

 

Report back in a day or so.

 

 

 

If you look at the very bottom of this page, you will notice that A22 is specified for up to 768 kHz on the I2S/USB inputs.

Hope this helps.

@Zaphod Beeblebrox When HQPlayer was released in the native version of code for the M1 processor of Apple (arm64 version), I noticed a very significant improvement in speed over the Rosetta II version. Do you have any clue when the native version of Mathlab will be released on order to allow same significant improvement to be brought to PGGB running on the this M1 Mac architecture ?

Before I discovered PGGB, I was contemplating upgrading my DAC to a Tambaqui. I asked some friends who are equipped with a Tambaqui to test the PGGB files and they did not report any improvement which is not very surprising knowing that this DAC operates an internal upsampling to 3.125MHz/32 bits.

But I am so impressed with the results I have today with PGGB files on my Gustard x26-Pro that I am tempted to challenge my previous decision.

Has anyone had the opportunity to compare a Dave fed with PGGB files with a Tambaqui ?

Thanks in advance
