Schiit freya preamp - any owners out there? Leave it on?

Yes, the input selector. One click to go to passive. No need to power off. I run expensive NOS tubes so put in passive after every listening session.
I never use the switch in the back & simply unplug system from wall when on vacation. Amp & DAC stay on 24/7 Being able to put tubes in Stand By was the reason I tried the Freya Plus to begin with, the Amazing SQ when paired with the right tubes is the reason I kept it. Using Bryston 4B3 amp, Nuprime DAC10 and Tubes are KenRad VT231 & Melz1578. Sound is sublime with Magnepan 1.7

Phcollie, you very smart and schiit is looking really good to me now. Have you ever measured watt use when in passive mode?

I have a Macintosh amp and a chord tt2 used to stream qobuz from a nucleus.

I have never measured any consumption. My last month power bill was only 107.00 for a 2600 SF home so I am pretty sure it is next to nothing. The 4B3 only consumes 500 milliwatts in standby mode so I suspect in passive the Freya Plus will only pull a single watt at most. They list typical consumption (active) at 40W.

How are you setting up your system?  I have everything side-by-side on a long, low shelf and find no inconvenience to the power switches being on the back.  If you’re stacking it in a rack or a high shelf that would be a problem. I turn it off after each session.

I own the Freya+ and asked Schiit this question. They said that even in passive the tubes were still getting power and you should turn it off if you are not using it.
