Hi Denon, As Audioman noted earlier, the stock Chinese rectifiers can lose their composure with complex orchestral passages, so it's worthwhile replacing them with NOS rectifiers. Audioman mentioned some rare (and expensive) examples, however in this Ayon circuit, the rectifiers are about one evolutionary step above the lightbulb. Rectifiers can be more critical in some circuits (eg: Modwright), however my Audio Engineer certainly didn't think that was the case with the CD-5s, hence I wouldn't spend any more than needed. Also remember 6H30DR tubes used to cost US$15.00 years ago, so don't be concerned about the price ($3.00). To address your concerns, there is no such tube as a 6CP4. That is obviously a typo. To clarify, Ayon recommended I use NOS Reflektor 6C4P tubes in lieu of the factory rectifiers. There are different suppliers of 6Z4 tubes, however the CD-5s has Chinese variants. It makes sense using the higher quality Russian tubes, but you can spend more if you like. If a website showed the CD-5s was specified with 6X4 tubes, that would appear to be an error. Cheers.
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
Ifyou need assistance with values and direction of signal path
