GoldenOne Posted July 2, 2021 Share Posted July 2, 2021 Just now, Extreme_Boky said: So, my question remains: how are you going to connect that streamer to May DAC? Using USB? Will that work? My assumptions (and the reasons why I'm asking these questions) are: 1. May DAC USB interface requires a specific driver that will govern data exchange between the source (streamer) and May's USB input interface (internal XMOS card) 2. I do not believe this driver can be installed on that streamer "motherboard" You don't need a proprietary driver for the May. It will work fine with any USB streamer. You need the proprietary driver for windows ASIO. But other than that you can use WASAPI or linux ALSA plug and play https://youtube.com/goldensound Roon -> HQPlayer -> SMS200 Ultra/SPS500 -> Holo Audio May (Wildism Edition) -> Holo Audio Serene (Wildism Edition) -> Benchmark AHB2 -> Hifiman Susvara Link to comment

I thought that, without the driver, the streaming options will be severely limited... to something like 192kHz.. or maybe even worse - to 48kHz only? On Windows it will work up to 768khz without a driver And on Linux it will work up to 1.536mhz without a driver (though some linux distros may only do 768khz) https://youtube.com/goldensound Roon -> HQPlayer -> SMS200 Ultra/SPS500 -> Holo Audio May (Wildism Edition) -> Holo Audio Serene (Wildism Edition) -> Benchmark AHB2 -> Hifiman Susvara Link to comment

Power supplies make a big difference so my guestimate is, May Level 2/3 would reveal a distinct and very noticeable improvement, but Spring 3 KTE could be pretty close with May Level 1 since Spring 3 KTE has the Titanis 2.0 USB module, and May Level 1 doesn't have it. Also, Spring 3 KTE w/preamp module vs Spring 3 KTE + Serene would be very interesting. Perhaps something @GoldenOne can do later this year? I've had a spring 3 here for a week or so now.

At max volume you can just about hear music with your ear to the drivers. Volume control works perfectly, and as expected, in SDM (DSD) mode, volume can also be controlled on MConnect (my control app) whilst in SDM mode - so this is just a problem with PCM. Any ideas? I also only get PCM upto 768kHz in both embedded and windows versions of HQPlayer using Holos AISO drivers... advice welcome. Anyone managed 1.536MHz in Windows 10 - in the windows system tray I can only select WASAPI - AISO driver does not appear as a windows option. Looks like I'm stuck with DSD for the moment. For the 1.536mhz support you need to flash the 30.12 firmware to the dac.

Won’t it compromise sound quality? Two solutions are to either use usb (likely the best option.

GoldenOne Posted July 22, 2021 Share Posted July 22, 2021 6 hours ago, scintilla said: No. It is because the noise floor is lower with 256 vs. 512 and 1024. There is a sweet spot with the Holo DACs with rates for best performance and it isn't the highest possible rates. Same with the AKM 4499 in DSD direct mode. This is a function of settling times, resistor matching and the randomizing algorithm used but at these high rates we start pushing the theoretical limits and 256 is what Jussi has shown to be optimal for Holo DACs. It isn't because processors can't to 7EC at higher rates. I do ADSM7 512+ fs with my machine just fine. 512+fs isn't an ec modulator. Ec modulators are considered to be the best afaik. Maybe @Miskacan comment but iirc he said that the ec modulators are preferable to the 512+fs ones https://youtube.com/goldensound Roon -> HQPlayer -> SMS200 Ultra/SPS500 -> Holo Audio May (Wildism Edition) -> Holo Audio Serene (Wildism Edition) -> Benchmark AHB2 -> Hifiman Susvara Link to comment

Good to know It is. 30.12 and 30.14 are interchangeable. Neither is newer than the other they are just different. From the factory the may and spring 3 ship with 30.14 because that works with any usb source. Whereas 30.12 whilst it does support 1.536mhz, doesn't always work properly with non-Intel devices. So they ship with 30.14 to ensure all customers can plug and play. 87mpi and KenMoreira 2 https://youtube.com/goldensound Roon -> HQPlayer -> SMS200 Ultra/SPS500 -> Holo Audio May (Wildism Edition) -> Holo Audio Serene (Wildism Edition) -> Benchmark AHB2 -> Hifiman Susvara Link to comment
GoldenOne Posted August 16, 2021 Share Posted August 16, 2021 I actually measured the May on the APx555 when stacked and when separated and there was no difference at all Most likely issue is either some interconnect near the power cord maybe? Or perhaps a poor contact on one of the pins on the interlink cable (try wiggling the interlink cable to see if it alters the noise, also try unplugging may, flipping the interlink cable and then plugging back in). It's very unlikely you're getting interference through two thick metal chassis. Especially when this is not normal behaviour. https://youtube.com/goldensound Roon -> HQPlayer -> SMS200 Ultra/SPS500 -> Holo Audio May (Wildism Edition) -> Holo Audio Serene (Wildism Edition) -> Benchmark AHB2 -> Hifiman Susvara Link to comment
GoldenOne Posted August 20, 2021 Share Posted August 20, 2021 Just now, Rune said: One thing that puzzles me is why so many put the May DAC directly on top of the PSU. The general recommendation has always been to put hifi separates on different shelves especially power supplies. Also there was many pages back concerns about heat. Again separate shelves is a good idea. The psu generates very little heat. It's the main dac unit which gets hot. Temps don't change whether you've got it stacked or unstacked. Main thing is don't put something ontop of the main unit. In terms of quality/noise, you've got two massive metal chassis in the way. The psu noise on my unit measures >-150dB regardless of if stacked or unstacked Rune 1 https://youtube.com/goldensound Roon -> HQPlayer -> SMS200 Ultra/SPS500 -> Holo Audio May (Wildism Edition) -> Holo Audio Serene (Wildism Edition) -> Benchmark AHB2 -> Hifiman Susvara Link to comment
GoldenOne Posted August 30, 2021 Share Posted August 30, 2021 11 hours ago, simonklp said: @rocky, I have been paying attention to this thread for quite some time already, since I own a May for more than a year. One of the information that I want to find out is something similar to your case. I have also noticed that there is sometimes sibilance especially on vocals from May, but it only appears when I play the PCM music by upsampling it to 1411.2k by using HQPlayer. Even though, I didn't find such sibilance at upsampling frequency lower than that (e.g. at 705.6k). In addition, before the upgrade of the last USB driver about a month ago, the situation was even worse, the sibilance was not just on vocal only. In addition, it also appeared to be a type high pitch sharp noise. But it did also only happen for PCM music upsampled to 1411.2k by using HQPlayer. In the past, I was not sure whether the problem was related to either HQPlayer, May, or other issues (e.g. other hardware). I have asked Jeff (designer of May) why this happened. But he has no idea, and only replied it should not be caused by the USB driver and the firmware versions. He has also said he has not heard of the feedback of this kind of problem from other users. This morning, I have found that by not using the JCAT USB Card XE (i.e. via the ordinary USB port on the NAA PC), the sibilance at 1411.2k PCM upsampling has gone. I doubt whether it is due the IC chips used in the JCAT USB cards may not be from Intel that may account for this problem. I would suggest that you may try to bypass the JCAT USB Card in your setup, and see if the sibilance will go away. Cheers. To add to this, it's known that you need Intel for 1.536mhz to work properly. When I was testing various usb sources with the may with the two firmwares I encountered four situations: 1) Intel, both firmwares: 'just works', no issues, measured performance was perfect at all sample rates. 2) Non-Intel, firmware 30.14. 'Just works' as above. but caps at 768khz 3) Non-Intel, firmware 30.12. Works absolutely fine up to 768khz. Above that it plays very robotic/weird. This was the most common situation for non-Intel devices. 4) Non-Intel, firmware 30.12. Works fine up to 768khz, and APPEARS to work fine for 1.536mhz, but it sounded sibilant, and when measuring, there was odd, seemingly random distortion content which was not present normally. Its likely that the jcat card falls into the 4th category there. And so that was unfortunately likely the issue. The tldr: if you want to use 1.536mhz, you need an Intel device. OR get the new usb card which should do 1.536mhz on any device which can support it. But for <=768khz any usb source is fine.

The May seems to sound great with many lesser Intel usb connections. My fitlet2 usb 3.0 (NAA) sounds wonderful so far Nope 30.12. If you use 30.14 then any USB source that functions properly should work. 30.12 is where intel works fine but everything else either doesn't work or appears to work but actually has some underlying issues. But yeah, given how good the May's usb implementation is and being fully galvanically isolated (not just the 5v/gnd lines like some dacs), I've found that USB source really doesn't matter. I even sold my SMS200 Ultra. If concerned then one could put an ifi iGalvanic between the may and their PC for reclocking/further isolation as it's fully transparent to the host and so 1.536mhz works fine through it if you're on intel 87mpi and KenMoreira 1 1 https://youtube.com/goldensound Roon -> HQPlayer -> SMS200 Ultra/SPS500 -> Holo Audio May (Wildism Edition) -> Holo Audio Serene (Wildism Edition) -> Benchmark AHB2 -> Hifiman Susvara Link to comment
