Revelation Audio Labs Cryoed Silver Umbilical vs Audio alehcemy OEM

I ordered a Topping D90iii Discrete to hopefully replace my 4-5 yo Audio Alchemy DDP-1 + PS 5 ~2008, (often available for < $1000/ ORIGINAL MSRP; $2695 IN ~2008 DOLLARS) that still sounds great, has easily revealed changes;  different cables, PCs, even footers, but is lacking a little transparency.
The fly in my ointment is the Topping volume control, whereas the AAs internal dac has an ANALOG preamp. I ordered the Discrete just prior to being made aware of Revelation Audio Labs Passage Cryo-Silver umbilical by AG member @Icherepki. He wrote: I’ve only tried the stock umbilical once, just to get a feel for the difference, and couldn’t get it out my system quick enough. Now Im no stranger to cables and was planning to upgrade the umbilical a couple years ago, but never got around to it. So... thinking, if it doesn’t knock my socks off, I’ll connect the D90 iii Discrete.
 
I just got it and it is a mind blower. This umbilical was all I was missing. If you’re on the hunt fo a quality dac/pre or if you have a AA DDP-1 + PS 5 I highly suggest stop chasing after any other dac, find an Audio Alchemy DDP-1 + PS 5  (THERES’ ONE ON AG FOR $699) and replace the OEM umbilical with this one for $289/0.5m, which seems like a lot until you hear it

I have completed a set of RAL umbilical cords recently, and offer:

1. The cables are a significant improvement over stock cables. They are well made and sound great.

2. Brad can make a cable to fit your specific needs (I asked for 1.25M length)

3. Dealing with Brad is a little ’challenging’ - especially regarding what he says in terms of the timing of construction of your cables and then actual shipment.

4. Brad is open to discounted price offers for his cables (ie. instead of $289/.5 meter, you could always ask if he could do it for $225-250)

5. I would recommend using Brad’s ebay storefront. Send him a message about what you are looking for, and then ask for some flexibility on sales price. He will then create a unique post, which you can "buy now". Ebay provides some ’buyer protection’ wherein if he has said he can get your cables constructed and shipped within 2-3 weeks after payment, you can ask Ebay for a refund if promises aren’t kept or if there is no/inadequate communication from the Seller.

All to say - very good cables and significant sound upgrade; but it may involve a little patience and ’communication effort’ to get delivery.

I also have a RAL DC cable from my HD Plex LPS to my Legacy Audio Wavelet II. It replaced a nice Ghent Neotech Cable, it is better. I also have had Brad make me an HDMI style I2s cable for the connection between my DDS and Terminator 15th DAC, that replaced a well regarded Tublus Argentus cable for the better. I also found on USAM a RAL RJ45 cable which replaced a Eno streaming system for the better as well. Brad's cables are really quite good.

I upgraded a Perpetual Tech setup I had some years ago with the Revelation cro'd silver, worthwhile upgrade.
