The answer is not in your post. Did you do level matched double blind tests?
David and LTiq: I have no idea of what you are talking about and I don't know who either of you are. So you are both correct. You just got the wrong person.You have absolutely no idea who you're talking to.
DM me, I'll buy them from you.Hi. New to this forum, and this is my first post. I wanted to share my experience with Vidar(s).
I've had 2 Vidars for some time now. Initially they were hooked to my B&W CM10's in the balanced dual mono bridged mode. This produced an audible 50-60 hz hum coming out of speakers, without pre-amp/source connected. The sound was also lacking the depth and finesse. Then I switched to vertical bi-amp through the unbalanced connection. Sound markedly improved and the hum was gone. As someone already pointed out these suckers have a significant mechanical hum coming out their EI transformer (I use Euro/Australian 240v model). I sent them back for the replacement and received 2 different units with exactly same problem. It took opening (voiding the warranty) them and fiddling with the transformer mounting to reduce the hum. It could not be completely eliminated.
I would not recommend this amp to anyone. It just feels like an unfinished and untested product. Purely on sound/price merits it would have made a sense, but the amount time spent fiddling with it, its just not worth it.
Unfortunately. 2 Vidars are one of very few audio purchases that I've come to regret.
Regards
surprising there's hum with 90 dB speakers. My 1.7i are 86 dB and I can't hear anything from the transducer even with my ear up to it. I can hear the hum if I put my ear right near the amps, but not from where I'm sitting while listening at all. Can you hear the transformer hum from listening position? If you haven't returned them, you could probably sell them and not lose much.Hi. New to this forum, and this is my first post. I wanted to share my experience with Vidar(s).

Apparently you got an offer while I was typing my reply...DM me, I'll buy them from you.

Yeah. I can hear mine humming from 2.5-3 m away.
It might also be DC in your powerlines, fixed my toroidial hummbuzzs with a blocker before.. fortunately I'm SMPS user these days.
I have had great results in what 'sounds' like noise reduction by isolating vidar with sorbothane, humfrees and most importantly the emotiva cmx-2 dc offset eliminator. Transformer is quiet as a church mouse now. Zero hum. I think it sounds better. Would be cool if there was a corresponding measurable decrease in noise floor.I’ve owned a Schiit Vidar for about a year now. My only complaint is a low-level mechanical buzz that can be heard from the unit itself whenever it is on. The buzz can be heard when the wires are disconnected from the speakers. It’s noise, but it’s not in the audio signal. I’ve read here that it may be from DC contamination of my household current, but so far I haven’t wanted to spend the money on yet another device to see if it can be eliminated. I can’t help but see it as a flaw of design and/or manufacture.
In my understanding of what I’ve read on this forum in postings by experts, the measured SINAD of Vidar puts it into the transparent category. That is is say, further improvements in this regard are an unnecessary waste of resources that cannot be perceived by the human ear.
The family of curves provided by Amir shows the distortion rising with frequency, but even worst case is imperceptible or nearly imperceptible, and out of my hearing range at 20kHz. The measured distortion at frequencies that are within my hearing range, I expect are imperceptible to me.
Class D will be more efficient, of course, but shouldn’t be able to deliver an audible improvement in sound quality. In fact, any improvement in sound quality (other than increased power delivery) should not be possible, right?
do you have some pics about that tweak, how you apply the sorbothane?I have had great results in what 'sounds' like noise reduction by isolating vidar with sorbothane, humfrees and most importantly the emotiva cmx-2 dc offset eliminator.

Duro 70, .13 sorbo washer between the case and rubber feet. You'll need to get screws to fit new length.do you have some pics about that tweak, how you apply the sorbothane?
