Power - where to start? Mains, chords, conditioner, filter?

An alternate route to a dedicated power line might be to purchase a YETI power backup system

A fellow audiophile just made me aware of this unit
- generates a perfect sinewave
- works just like a UPS 
- but with a larger capacity
- handles large transients with ease
- on his system a YETI 1000 will run the ENTIRE system for over 5 hours
- you can leave it plugged in - or not

He swears by it, but I have not used one, so it’s hearsay, but we have emailed many times, so I do trust his opinion and judgement

I would also get a good power cable for the streaming device - take a look at these power cables...

All of their products are first class and provide stunning sound quality

Hope that helps - Steve

@dtximages - WRT...

Can you explain how this works and where it fits into the system?

Having never use one I cannot provide a difinitive answer, but from what I understand ...

• plug the YETI into the wall
• plug your components into the YETI

It seems to be part power generator and part UPS
- It generates clean sine wave power all the time
- if the power goes out it runs off the internal battery

Hope that helps - Steve

David - thanks for the update on the YETI - Good to know

But it does seem to offer a more affordable opton than the $$$AUDIOPHILE regenerators, provided  your listening session is less than 4-5 hours (depending on system)

I think we will see more units like this as development of battery technology progresses.

There are some pretty exiting developments in the works that offer more power for the same size of battery and will not burst into flames if punctured.
e.g.

Fortunately for me, the power to my house is very good, so I do not use any kind of power conditioner/regenerator..
