@oedstrom11 - your Schiit components are much better than most people realize - they just need very good cables!
The Amazon XLR are fine for now - so stick with them
I would start with speaker cables and then power cables
Take a look at Zavfino cables
- Try the NOVA OCC SPEAKER CABLE 12AWG - they should work very well
- the power cables start around $150 per cable
- if possible get the FINA OCC POWER CABLE 14AWG from $215
- or the LEGION OFHC 11AWG POWER CABLE from $288
Unfortunately this is the tip of the "cable iceberg", but for a "modest" investment the sound of your system will improve considerably.
Once you complete that upgrade you can try their ARCADIA OCC INTERCONNECT CABLE - granted it is single ended, but it will be a nice upgrade from the Amazon XLR cables
The Zavfino product range is one that stands out above the rest of the commercial brands just because of the wires//insulation/cable geometry they use - their cables are an advanced design and they are extremely well built - PLUS - they actually perform extremely well.
They are also very well suited to your audio components.
They also have some very good higher end products that really excel - when you feel the need to upgrade
There are better cables out there, but they are much more expensive and better suited to higher end components
I realize you may have reservations about cables, but I’ve been building cables for around 15 years and in that time I have installed cables on
- small mini systems costing around $350,
- bluetooth speakers
- my own modest 2 channel system system
- and systems up to $60,000
- each time - cables have provided the best bang for the buck upgrades I have ever implemented
e.g. The cables I had on my Bifrost cost more than double the price of the Bifrost, but it sounded excellent !
So try the Zavfino speaker cables above and then perhaps a power cable - I think you will be able to hear the difference
BTW - cables can get very complex and very expensive, but there are more affordable DIY alternatives out there and there are people that will build them for you
So If you have any questions just ask
Hope that helps - Steve
