Why in some instances does changing streamers makes a bigger difference?

Thanks for your thoughts.

The problem with Aurender is that they do not support Presto, the streaming service that I use 90% of the time.

Even on the used market an N20 seems to fetch $8k.  I am contemplating upgrading my TT and getting a CJ 62SE so ...

I have wondered about a voltage stabilized power conditioner, I think my power is quiet, I am the only house on the transformer,  but there are days when the voltage is down.  I think that would make a difference.

Given the architecture of the DAC I think that gains from changing the T8 would be marginal.  I had a lesser Aurender that I used for its SSD and I have played games like cheapo USB cables and nothing seems to change the K-01XDSE's sound - as long as I stick to the USB.  A stated aim in their USB design is isolation from upstream issues.  I truly appreciate your thoughts.

I think there is more to power conditioning than removing DC or other noise coming from the wall, and it is related to the main concept of the video link in my original post.  Analog circuits and signals are susceptible to noise.  Whether the noise is generated in your DAC, produced in another component, like an inexpensive streamer, a switching power supply, or coming from adjacent cables, especially power cables, it can affect the signal that eventually reaches your transducers and your ears.

A good power conditioner can, not only clean up DC and other noise in your supply from the wall, but it can help keep noise generated back into your power distribution from other components plugged into it.  Depending on how much noise is entering your home via supply from the street and how much noise your gear is feeding back into the distributor directly from the component or indirectly from EMI in adjacent cables, a good power conditioner can create a quieter background.  It may seem obvious that better gear with more sophisticated power supplies would be immune to this benefit, but some people with very high quality electronics report benefits from adding a good power conditioner.

YMMV

I just stumbled across Analoghlic a couple of weeks ago and I have watched several of his videos.  Easy to understand and he’s not selling anything.

Different streaming software/programs can make a huge difference for sure!

Regarding the hardware used, I believe a well-engineered device, of which there are many at various price points, running good quality streaming software properly, should outperform a device that is not for some reason, and that some more niche products may offer a unique house sound that appeals to some enough to justify the cost, but that’s about as far as I would go.  

With good streaming software, like Roon or Qobuz,, any common household computer, tablet or smart phone can be a formidable competitor by simply using an asynchronous USB connection to a good quality external DAC.

@knownothing Thanks - food for thought.

As I may have mentioned my present setup is the Monster unit that does have isolation between outputs designed to prevent noise generated by a component from affecting others, in addition to overall filtering.

Also my phono stage, T8, preamp & power amp are on MIT Z-cords which also have filtering.  Per the manufacturers instructions the K-01xdse uses the supplied cable, and the SRS-FS725 frequency standard (clock) is on a hospital grade cable, fed from a UPS as it is "always on".

I am not sure what improvement I could get from the significant cost to upgrade the PDU - but I'm keeping my eyes open for a good used bargain to test.
