ifi ipower

   Thought it might work well with a Vista phonostage. Specs are really good price is fair [$99] IMO.
   ifi appears to offer some interesting stuff for a good price. The ipurifier looks interesting as well.
   Not a dealer.

Just make sure you order the correct voltage for the unit it goes with. 

Works with a Raspberry Pi3 as well with the 5V unit.

  Thanks Hal. This ifi audio appears to offer some interesting products. priced fairly as well.

Ifi  makes some nice products. I have this on the output of my Bluesound Node

    That product caught my eye as it makes good sense. Can you describe the result before and after. Did it alter tonality in any way ?
    Did it color the sound in any way, meaning brighten or darken the sound ?

It didnt change the sound at all. In my opinion it  eliminated the background noise so all you hear is the music, cleaner music .almost like the Uberbuss

   Thanks. Have one coming.

The iFi AC iPurifier just arrived and going to give one a try.  A $99 product.  This looks interesting with the Active Noise Cancellation ideas supposedly employed.  Also tests your AC line for standard connection problems.

For a system, they recommend 3, but should be able to hear something if it works with one. 

Going to put mine before the PI Audio UberBUSS running the MS-3 Music Server and dspMusikLCD digital processor and see if anything changes with the noise floor.

Let us know.

Non-audio observation.

I put my Fluke 43B power line analyzer in one socket.  Looked at both the line AC waveform and harmonic distortion.  Then connected the iPower to the other socket.  No change in either here with fairly clean power with about 2% THD at 122VAC.  Top of the waveform is partly flattened off from loads.

Since the unit talks about removing line hash, the above is not a surprising a result.   What is needed is an RF analyzer to see the HF content and noise transients before and after.
