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...

2266 and 2267

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?
