Ayon cd5-s or Skylla -2 dac. Big improvement

There is 11 steel fuses in the Skylla dac and 12 in the cd5 player
First Synergistic research Big MIGs under the unit are a noticeable upgrade
A good quality aftermarket power cord, plug all open RCA, and xlr openings with the Cardas caps, to block rf noise from entering,
And the biggest by far is replace all the fuses with Hifi tuning Supreme
20mm T fuses yes it is a $500 bill but a small price to pay for
These Silvergold fuses have 8x less resistance vs steel just check the Silver resistance, the level of low level detail , resolution, and stereo separation is Very apparent as well as dynamics being a bit quicker.
If you have invested this much in these units already this is ano brainer
This is possibly better then a cable upgrade and all that steel in
Common fuses is a Huge bottleneck and all that low level hash
Is Gone,clarity you didnot realize was there before. P.s
