A Skeptics Digital Upgrade Journey


2 months ago I argued against the benefits of high quality digital cables. It’s just 1’s and 0’s right?

My Bluesound Node (N130) was a convenience - decent SQ for casual listening (SXM radio and Tidal). Focused listening sessions were vinyl only.

Back surgery forced me to take another look at digital - the records were too low to for me to get and my wife was doing enough without taking requests.

I started looking at DACs, and Denafrips was on my list. Thanks to @drmuso I ordered the LSY PSU with LPS ($280) from BEATECHNIK also run by Alvn Lee from Vinshine Audio.

I added a tube DAC from Black Ice and they arrived on the same day along with a Coax cable from Analysis Plus. Interconnects to amp were Nordost Purple Flare. Hard wired Blue Jeans ethernet.

  • The PSU+LPS on its own made a huge, immediate difference. If you have a Node and it’s out of warranty or you don’t care about voiding the warranty, this is a big bang for the buck. Customer service was top notch.
  • Adding the DAC improved the sound but I was underwhelmed even after over 100 hours on the tubes. I switched from the AP Coax to the supplied USB cable and things got better but highs were still a bit too bright/harsh.
  • I ordered Zavfino interconnects (Arcadia OCC) and USB cable (Majestic OCC) - immediately things warmed up. Sent the AP Coax back.
  • Lastly, I replaced the Svetlana tubes that came with the DAC with some NOS Mullards from Brent Jesse - let them warm up for 24 hours and WOW - now the digital source was warm and rich and sounding more like my much more expensive analogue rig. It's still early days on the tubes.

Very pleased with the outcome and I think the all in cost of $2,570 is pretty reasonable.

  1. Node $600
  2. PSU/LPS $280
  3. DAC $900 (on sale direct from Black Ice, list is $1,200)
  4. Cables: $340
  5. Tubes: $450

Lessons learned: everything matters including digital cables, apparently it is not just 1’s and 0’s. Serious listening library expanded exponentially.

Thoughts on my choices/path? Any one else done something similar?

A few more tweeks...

  • upgraded internet speed from 250 to 500 mbps - this made a noticeable difference on it's own
  • added an ASUS AX5400 router and now run all wifi devices off that, with the Node hardwired into the Cox modem (Broadcom chipset) - this didn't make much difference based on a quick comparison
  • added Symposium Roller Block Jr's under the Tube DAC (I had an extra set so no extra expense) 
  • The Pangea AC 14SE MKII Signature PC didn't make any noticeable difference

Unrelated to the Digital source, I did add a Synergistic Research Orange fuse to the integrated tube amp - this was a noticeable improvement - I felt it slightly improved the bass and the sound stage seemed more defined. I have a premium fuse coming for the DAC.

Once the Zavfino PC arrives I'll be done (really) - I'm hoping I hear an improvement.

Crap - the ASUS router is adding noise to my analogue chain. A faint, rapid beat, seems like it's in time with the flashing LEDs. It's going back.

Thanks for the tip on the gold power chord. Using it on my Node with an adapter. Very good results. I bought the Rhodium one too but have not tried it yet. Like to do one tweak at a time to understand the changes.

@dolfan  hope they work out for you.  Low risk  at that price.  They take some play time to be at their best.  In think they work best on the lower draw components like streamer, DAC …. I am not a Rhodium fan.  It is lower in conducting and its main benefit is that it’s a very strong/hard metal and the plating won’t rub off for heavy use plugging in and out.  I like copper then gold for home audio use.

@dolfan I highly recommend the PSU-LPS upgrade noted in the OP for the Node if you don’t mind voiding the warranty or are out of warranty.

you could use the new PC for the LPS without an adapter
