And if someone is "only" using the LIO as a Pre/DAC with the mRendu power option - is there any reason they should power down the LIO? I'd assume it sounds better if left on, like most DACs and electronics.
The main reason to power down the LIO after each use is to save energy, and if you are running tubes, you are clocking more hours
on the filaments. Of course there are two schools of thought regarding what wears them out more (leaving them on all the time when not in use, or the cycling of power). Who really knows? LIO turns them on very gently, so I'm fine with cycling the power.
- I personally PWR down the LIO after each use and do not find that it takes long to warm up and sound its best. It sounds great as
soon as it turns ON and is ready to go after the 30 second warm up sequence. And I don't mind the "ritual" of turning it back ON
and queuing up the next LP or track on the computer. That's just me...
- I have read on the Sonore forum that the microRendu *could* sound different with warm up time, but in all honesty, it sounds the same
to me. As soon as it boots up and starts playing music, it sounds fantastic.
But the decision to leave on / turn off is up to the user.
Related to the Tubestage jumper. Does device turn on promptly if the jumper is set to skip the Tubestage or it still has the 30 sec warm up feature activated?
The AVC/Tubestage does not send a signal back to the LIO saying "tubestage is now bypassed" - so the delay is still 30 seconds.
If you only had an RVC volume control (with no tubestage module populated in the LIO), then there would not
be the 30 second warm up mute delay.
Also - if the LIO MOSFET AMP was separately turned OFF on the front panel ("AMP" button set to OFF), and you turn it back ON, there
is an approx. 10 second mute delay. This is to allow the amp to power up / stabilize before we un-mute it to avoid any pops.
I haven't even tried the bypass yet so I'm of no help. I've been busy - LISTENING!
Glad to hear this, jtwrace!
That was the whole point of it. Turn it ON, LISTEN, and ENJOY how good it makes your favorite music sound.
Discussing things like "leave it on / turn it off", delay time, etc. is such a drag compared to just listening and enjoying it. At
least we don't have to talk about power cords, dedicated mains, and outlets here - Lol!
Give me a day or two to compare these two setups:
microRendu powered by LIO -> LIO DAC
microRendu powered by UpTone Regen PS or iFi PS -> Auralic Vega plugged into a Pi Audio Uber Buss
Looking forward to your comparisons, George!
