Whilst I am happy with the Caiman II for Spotify etc. I feel it makes very little difference to the output from my PD-S703 when used as a transport.
I have tried optical and coax cables between the two and just stick to the RCA now.


So the first question is, what is the weakest link?

The 2nd question, what would you do about it?

The digital system comprises of:

Spotify Premium/Pioneer PD-S703 to Caiman II.
Caiman II to Firebottle KIN.
Firebottle KIN to Firebottle Monos.
Firebottle Monos to Electricbeach FH3 with Batpure supertweeters.
