Ckuple of questions on upsampling dsd64 to dsd1024. Does the upsample process convert to pcm first. Also if I feed the pro idsd with dsd512, is it a pure direct through or does the filter e. g. GTO come into play.

Pro idsd is 15vdc.I beleive ican is the same, should be marked as such on input. LPSU can be very expensive, I use one but noat the ifi one. I don't have the ican, but if you are looking to have lpsu for both, have a look at the hdplex 300w with 2 outputs voltage configurable.

I input hqplayer upsampled dsd256 to ifi pro idsd and further upsampled that to dsd1024 using GTO. Just about every comment I read that's not a good idea, but I like the result.

That is strange. I would agree if the coherent clock is the problem, then probably USB shouldn't work too. Is it possible that with USB, it can use the Amanero clock instead of the coherent clock (that doesn't seem to make sense either). BTW, the upgraded version uses the same Amanero module...

If it's power to s/pdif circuitry problem only, then usb input should work. Try that. Are you sure it's LKS. Have you try system with different dac. If it doesn't seem to be decoding, may be the clock. I would use multimeter to check if there is correct voltage to clock. .

The 004 does use many high quality components. I would say a few years ago it was one of the better dacs on the market. In my mind, it has a few shortcomings, and it's a pity LKS did not come up with a new version like a 005. I don't like the Amanero usb/i2s bridge they used. They fiddled with...

The 004 is similar vintage to your dac, a few years old. Why aren't you looking at newer dacs, like from Vinshine themselves. Personally, I think technologies move on. In general, you get improvements at cost effectivity with newer versions.

Just start the firmware update program again (just start it, don't run it). The first screen shows you the current version. You can then exit without running the update again.

For those who are looking for interesting experiment to improve their sound system, I have been playing with Bug Head Emperor utilities from a Japanese developer Hiroyuki. First there is MinorityClean http://www.mics.ne.jp/~coolverse/MinorityClean/. You can run it as a service on your PC which...

I don't have the Freya but I think they use 6SN7 tubes. My preamp section uses both 6SN7 and 6SL7. Have rolled many different NOS tubes over the years right up to expensive ones like the Russian 1578. Problem with buying NOS is fraught with fakes and NOS that are not really new. Right now I am...

Signalyst price Lenny, didn't you tell me off when I said it's a good idea to introduce some tubes into the overall system?

May be you can re-flesh the firmware to same or different version to see if it makes any difference.

Where can I get this handy tool?

AU $482.55 5%OFF | High stability accuracy GPSDO GNSS Disciplined Oscillator Frequency Standard https://s.click.aliexpress.com/e/CKTd1cZa You need a male bnc to male sma connector as well. Spec is more accurate than atomic clock. For gps, the dac needs to be under 3m to a window so you get...

Did anyone try the new Topping DX7 Pro. Read some really good reviews. Same ESS as LKS and I think half the price.

Almost is never good enough :blush:

Jriver has a upgrade discount now on for the upcoming jriver 26. For me, one of the big enhancement is with the newer versions is a 64-bit version of jriver which optimize system resources assuming your OS is also 64-bit.

If you are using the standard clock on the LKS, that may be the bottleneck. Accurate clocking is important for re-sampling at high frequencies. The other suspect will be the LKS power supply. Variation in voltage will cause jitters amplified with the re sampling. That's probably why many people...

In theory (according to https://www.mojo-audio.com/blog/dsd-vs-pcm-myth-vs-truth/) and I quote "This is also why advanced player software, such as JRiver, offers Double-Rate DSD output. Using player software that upsamples DSD64 to DSD128 or DSD256 significantly improves performance by putting...

Enough to upsample to 256k. For 512K, you need a CPU with turbo frequency of 8MHz. Neither Intel or AMD has come up with that yet.

The new hqplayer ec modulators are really resource hungry. My i7 8700 with 1660 ti can upsample only to 128k.

The Sonore Signature Series Rendu has ethernet input and i2s output. But even Sonore is moving away to usb based setup with their new offerings. I feel usb has come a long way and I don't know you gain much by trying to avoid them. Often it's a 2 edge sword. The pink faun i2s pcie for example is...

The Pro iDSD layout does not make it easy to swap tubes. Very tight fit and have to be careful pushing the tube into the slot swith not a lot of base support. If they don't work, it is possible that you did not get it in properly. I would try again.
