I wonder if there would be any benefit to upgrade to the Freya from the SYS if I would only use the passive mode. Some say that using balanced cables all the way can improve the sound of some equipment. Although the SYS is designed for two inputs and one output, it can also be used in reverse configuration with one input and two outputs; it just changes the way the volume works. (My power amp got too loud too fast that way, for example.) And, as I mentioned before, it makes a soft scratching sound sometimes due to the potentiometer. The Freya should have none of these issues, and also enables dual mono for the Vidar...but I'm still averse to shelling out $699 for a preamp since it would be doing nearly the same thing as my $49 one.
I'm also curious about the Vidar. Have you compared it to other power amps? Got any impressions? Did you also compare how it sounds in normal mode (just one of them driving the speakers) rather than dual mono? Would you recommend that others buy two or do you think it's overkill? Any thoughts on what accounts for the better sound compared to cheaper amps? (Assuming it does sound better.)
You don't actually stack them all, do you?
I haven't tried Vidar in anything other than monoblock mode, I'd imagine they will do fine for most people running them stereo, unless you have harder to drive speakers and like to listen to it loud. Most Cheaper amps are Class D which IMHO is fine for subs etc... but just doesn't sound nearly as well for full range.
The only Schiit I have in my "2 channel" setup (it's really 7.2, but I listen in 2 channel "Reference Stereo" at least 90% of the time) are a pair of Vidar. Because it is a multi-channel system I'm using an Oppo 205 as the source and DAC, from there it goes into an Emotiva XMC-1 (in "Reference Stereo" it is 100% pass through 2 channel mode) before being sent finally to the pair of Vidar (all balanced).
I originally had an Emotiva XPA-5 Gen 2 for an amp before upgrading to a pair of Parasound JC-1's and there was a NIGHT and DAY difference between those 2. I purchased a pair of Vidar for a second system and decided to break them in on my main system to see how they compared to the JC-1's, I was blown away with how well the Vidar performed in 4 ohm mono operation. I tried to get them to go into thermal protection but I ended up giving in before they did, and they sound every bit as good as the JC-1's IMHO, enough so that I'm still running them in my main system 4 months later...
