Ian Canada streamer - Flagship I2S update the clock SC-Pure question?

[LongLong00]

Hello, i will update the clock to SC-Pure. Musik play from Qobuz and Tidal with MConnect from ipad.
DAC is Holoaudio Spring 3.
Must i buy 1 clock 45 or 49mhz or need i 2 clocks 45 and 49 mhz? I dont understand this?
thanks

I have the same question. I would like to upgrade a TransportPi Digi to SC-Pure. Do I just need to upgrade the stock 45 clock? Or both 45 and 49? Is there any gain in performance in replacing both clocks? Worth the extra cost? I guess I do not understand the role of the two clocks and how upgrading only one would be sufficient. Thanks for your help

I order yesterday one 45 mhz and one 49mhz
before it is sold out

It all depends on what source material you want reproduced. If it is redbook (cd) quality....as are most of my files...
And you want to buy only one clock because of costs get the 45mhz.

For playing tracks with Fs: 44,1 - 88,2 - 176.4 ... you need a 45 MHz clock
For playing tracks with Fs: 48 - 96 - 192 ... you need a 49 MHz clock

The streamer does automatic switching between the clocks depending on the incoming signal.

I ended up getting both clocks (45&49). Thank you for your help!

im resampling everything to 176,4khz so the second clock isnt really needed for the 44,1khz family, thats why i just bought a 45mhz accusilicon clock, there was a small difference indeed with the upgrade

you can also choose 2 different clocks if you would like, i left ian canadas stock clock for 48khz in

the lower frequency clock is for 44,1khz family (so 88,2 and 176,4khz too and others higher up) and the 49mhz one for 48khz family (48KHZ, 96khz,192khz and so on)

kinda wanna test the SC-pure but i dont think the price is worth it, it probably is a improvement but YMMV if the upgrade is worth the 200 or 400 euros
