I want to ask Topping to do the test and send the results, but I want to be very clear with what I ask them to do. How does playing a 1 kHz tone show a difference between 11.2 MHz and 12.2 MHz support? @Yviena did you ever do this test? Link to comment

If it only uses the 11.2 MHz the 1 kHz tone will play at I think about 918 Hz. Measure the output with a spectrum analyzer aurally or an oscilloscope electrically. asdf1000 1 https://audiophilestyle.com/profile/21384-solstice380/?tab=field_core_pfield_3 Link to comment
jimdukey Posted April 20, 2020 Share Posted April 20, 2020 I've been really happy with the various changes to HQ player in the past months. I have been using the ASDM7EC Modulator for DSD 128, on an iMac. I got a Fav Gerry Mulligan DSD 5.6 Download of "What is There to Say?", and to my surprise, I wasn't liking it, too aggressive treble, not the warm wrap-around textured sound that I was used to from the Re-issue LP I've had for years. At Miska's suggestion, I tried the ASDM5EC Modulator just now, and Viola! I don't have any CPU issues with the #7EC Modulator, but now I'm thinking the #5EC is possibly better suited to up to DSD 128. I'm just using the Poly-Sinc-ext2 and Mytek ( also Lampi Euforia). It sounds just the way I thought it was going to yesterday. So I'm sticking with it. Am I crazy? Well... Link to comment

Solstice380 Posted April 20, 2020 Share Posted April 20, 2020 @jimdukey We were just discussing favorites in EC Modulators thread. It could be that your DAC does better with the 5. I have a Lampi that doesn’t use the ladder for DSD just a filter and the EC5 sounds very good. https://audiophilestyle.com/profile/21384-solstice380/?tab=field_core_pfield_3 Link to comment

I think maybe 1 or 2 people on earth know what's going inside. But it does sound glorious. Plus I imagine you're throwing all kinds of test inputs to work out what it's doing on the DSP side 😃 Link to comment

asdf1000 Posted April 21, 2020 Share Posted April 21, 2020 I think it was established Oppo 205 does not support 48k base rates here https://audiophilestyle.com/forums/topic/19715-hq-player/?do=findComment&comment=873779 And in ASR's measurement I see spike at just under 900Hz , so is that what you're looking for?

asdf1000 Posted April 21, 2020 Share Posted April 21, 2020 Topping's even cheaper E30 DAC features AKM DAC chip (4493) and Topping confirmed when it is booted in DAC only mode, it also runs in DSD Direct mode. https://www.audiophonics.fr/en/dac-with-volume/topping-e30-usb-dac-ak4493-32bit768khz-dsd512-xmos-black-p-14486.html Link to comment
asdf1000 Posted April 21, 2020 Share Posted April 21, 2020 From the E30 manual there are 2 DSD filter options: http://www.tphifi.net/drivers/e30_manual.zip And for D90: http://www.tphifi.net/drivers/d90_user_manual.zip Solstice380 1 Link to comment

They use 44.1k sampling rate and PCM input. To measure this you need to use 48k-base DSD input... If it is played with 44.1k clock the peak appears at 918 Hz instead of 1 kHz.

The easier we can make it for them to test, the quicker we can find out. They don’t have HQPlayer or do upsampling. Link to comment

It’s much easier to send them a test file than get them to work out HQP. There may be more new HQP users if this is identified to be HQP friendly... DSD Direct and both family rates supported. More affordable options than RME. Link to comment

The fundamental would be at ~918 but this data shows the main peak right at 1 kHz. Was that 1 kHz signal generated at DSD x 48? The other side spurs are just distortion products. asdf1000 1 https://audiophilestyle.com/profile/21384-solstice380/?tab=field_core_pfield_3 Link to comment

No. I'm hoping to get a DSD x48 test file from @Miska that I can send to Topping to test. This would be the quickest way to get the info from them. I don't have time to teach them HQPlayer and they don't know what it is and we don't know if there really are many Topping users that use HQPlayer, so they probably have no motivation to learn.

Popular Post MemoryPlayer Posted April 21, 2020 Popular Post Share Posted April 21, 2020 Piotr Plawner, Pawel Przytocki & Arthur Rubinstein Philharmonic Orchestra playing Emil Młynarski (1870-1935) Violin Concertos Nos. 1 & 2 in 24Bits-96kHz upsampled to DSD256 AMSDM7 512+fs is the most beautiful album that I have heard in 2020.

asdf1000 Posted April 22, 2020 Share Posted April 22, 2020 I created the DSD256x48 test files using the above 1kHz tone. I set HQP Pro volume to -6dB. I used ASDM7EC and ext2. Any other test files I should send to Topping, since they are happy to measure @Miska ? I am happy to convert to HQP Pro if you can point me direct to the PCM test files. Happy to share Topping's results here. jamesg11 1 Link to comment
luisma Posted April 22, 2020 Share Posted April 22, 2020 Hello everyone, anyone with a Pro-ject S2 DAC and Roon and HQPe having strange issues? Like playing with specific HQPe settings like these And Roon not using it properly and sounding slowish and weird with reverberation (see below) like no upsampling being made Link to comment
luisma Posted April 22, 2020 Share Posted April 22, 2020 Restarted the DAC and NAA, fixed it, weird thing, this never ever happened before with the Project S2 which is IMO a very straightforward DAC (when used on 384 and under) Link to comment
