i hear the static discharge with MKII at the begining of every track. i did not hear that before with the MK1
LG has poached on PSA remote âfreqsâ for years.
Some questions whose answers might help narrow things down:
What inputs are you using? Whatâs your source device and/or what software are you using on your computer? Do you hear it only, for example, when going from PCM to DSD, DSD to PCM, only between DSD tracks, when sample rates are changing⊠Are you using automatic input select? If so what other device might be playing in the background.
Oh⊠Interesting⊠Sorta pain in the ass LGâŠ
I had no idea about LG, Iâm glad I have a Sony
I use HDMI for both streaming and CD. No change from Mark I setup. I use ultra and optical Rendu for the streamer side and the perfectwave SACD transport for CD play. Ticks on both inputs.
I use comcast into Roon. Ticks are heard on my ripped CDs and Qobuz streaming via Roon.
On the Transport HDMI I hear pops between redbook to redbook CDs and between tracks. SACDs are the same
On the streaming side DSD 64 and 64 to 64, 64 to 128 and 128 to 128 and 256 to 256 all have the same pops
PCM redbook, 88.2, 96k, 176k, 192k all exhibit pops between albums, between album tracks, and between data rates.
As for auto input select there is no difference between manual and auto select. I didnât have the not playing HDMI source playing while the selected HDMI source was playing.
Hope this helps Ted

I love my LG OLED, but it does sometimes interfere with PS Audio gear (and the other way around). My work around is to turn on the tv and select TV inputs while hiding the LG remote from direct sight of the PS Audio gear. I can then adjust volume of the BHK Pre with no effect on the LG TV.
If I could ask you to run an experiment. Turn off the power or unhook the cables on the source(s) that arenât playing and see if that changes things. The next release of the FPGA will likely change things a little so please report back about that too.
Interesting. Iâve heard a crackle every now and then at the end of a CD (over SPDIF). I havenât heard any pops at all streaming Roon at any resolution.
BeefâŠRightâŠI did see download only on site.
Anyone care to burn one to cd format for me? If soâŠI will pay the Audiophile Society site the money asked forâŠand the cost and shipping of the cd to my residence! I like the album but I only listen to cdâs.
Turned off mains power to SACD playerâŠ.streamer still pops between tracks. Unpluged the streamer and the SACD player still pops.

Kenneth, I have been deleting your mobile number from your messages so bots do not get it. I suggest not posting personal information.
Hmm. When the next FPGA release comes out, please let me know if it changes things. Pops between tracks isnât normal and, for example, I (and many others) donât get them with the transport or JRiver, foobar2000, etc. Iâll keep my eyes and ears on the lookout for more details.
This happens with my LG often when using the PSA remote to change volume on my BHK Pre
My P10s can power up if i point the LG remote towards them - not sure what I press on the remote to cause it.
Is it possible itâs similar to the Mk I? Mine (with Bridge) has pops between PCM and DSD (not the other way around) since the beginning (not critically loud).
Every source has the possibility of poping on start and stop. More used to pop when they went from PCM to DoP or back. I asked about specific sources so I could possibly narrow things down. With only the PST connected I didnât expect any pops between tracks. If there were some other things connected it could point towards a bug I fixed in the FPGA and/or a new bug I donât know enough about yet.
The DS locked onto an input in less than a sample (there are a lot of bits in a sample to pattern match a clock to.) Most DACs take far longer to lock so often a few initial bad samples are masked during the longer locking.
For the DS I had a 18mSec ramp up whenever any input changed (not a track change but a different input or a different sample rate, etc.) Unfortunately, when I was debugging before Sunlight I had shortened that ramp by about a hundred or so and forgot to put it back, so Sunlight had more pops on changes than previous releases.
The DS Jr has a feature that the DS didnât: optional automatic input selection. The DS Jr customers have grown accustomed to the foibles caused by sources that donât stop their signaling when paused, etc. But the DS Sr customers are now experiencing this for the first time so they arenât used to deconvolving weird source behavior with auto input select from other potential track transitioning problems. (When in doubt explicitly select the input you want to listen to,)
For the Mk II I put the 18mSec mute on input changes back but I also fixed a problem with the DS that when a source just stopped cold it didnât notice the loss of lock, often for seconds. With the currently released Mk II that quicker loss of lock can expose more crud in the previously active input signal.
For the next Mk II FPGA release I rewrote the logic for qualifying a new lock to:
- It will always take at least 31 identical rate detections before we ânotice itâ
- We count up on every bad rate by 31 and down on good rates by 1, this keeps short runs of valid rates in the midst of bad rates from causing a blip
- We double the time out for every transition from a bad rate to a good rate or vice versa, this severely punishes rate chattering.
I hate heuristics but trying to keep flaky inputs from messing with auto input select or causing noise as they almost work and then fail again is something I wanted to fix. Also I donât like getting any crud when a digital input cable is unplugged or plugged back in.
I got the FedEx tracking number that my unit will be back. I purchased 8 HDTT DSD256 files from their Black Friday sale and will test them on the MK2. I bet they sound a lot better on it than DS. It should be fun 
FWIW, using PST/I2s input to MkI and Mk2 only, I have always gotten initial static on SACD start up. Now, with the Mk2, I get the same thing on SACD startup and detect the same âpopsâ between some SACD tracks and some Redbook tracks. I will listen more closely over the next few days to see if there is any consistency.
I just tested this scenario with Audirvana and do not get any pops between transitions from any format.
