@peareye I’d say invest in the best clock you can afford, then upgrade other stuff as and when you can afford to. The OCK-1 is great, I was very happy with it, but after 6 months temptation got the better of me and now I’ve heard the OCK-2 I can’t go back.
What’s your network chain to your MacBook btw? As if it involves an Ethernet connection I’d strongly recommend an Ifi LAN iSilencer. For USD90 it was an excellent bang for buck upgrade to my streaming based system and I already had a very good LHY switch.
