Speaker Cables and Digital Coax: Pine Tree Audio or Signal Cable ?

Looking for some cables that are a good value and I've seen these two companies mentioned. My system is pretty good:  Van Alstine SET 400 Amp, Van Alstine T-10 tube pre-amp, Salk HT2-TL speakers, Denon HEOS LINK music streamer, Rotel RCD 991 AE CD player,  and I recently added a Merason Frerot external DAC. The Merason was a nice improvement on an already nice sound.  I have a Pine Tree $45 S/PDIF cable from the HEOS to the DAC and it sounds good but I have nothing to compare to. Yet. 

Can anyone recommend, or compare these two companies products ? I'm on a budget so I'm looking at the entry level S/PDIF cable between the CD player and DAC, and would like to try some of their entry level 10' speaker cables with banana connectors. Thanks.
