Schiit Vidar 2 Stereo ASR Amplifier Review
This is a review and detailed measurements of the Schiit Vidar 2 stereo/mono class AB amplifier. It was sent to me by the company .
Nice to see Schiit (finally) put a stand-by switch in the front. They usually have only a power button in the back.
Being a class AB amplifier with a linear power supply, the case is quite heavy and front loaded. The sharp fins make it hard to transport but that is a one time hassle.
Overall design manages to look unique and yet attractive.
There is a rather long delay before the unit goes form standby to on. Here is the back panel:
It is a shame we don’t have trigger input. Or balanced input for stereo (the one there is for bridged mode).

Schiit Vidar 2 Amplifier Measurements
As usual we start with our dashboard:
Mains noise was variable depending on how I grounded it. You may be able to do a bit better (or worse) than I did. 2nd harmonic distortion dominates and that is what sets SINAD to 88 dB which is good bit above what Vidar did (right highlight):
Noise performance is significantly improved over the original Vidar:
Frequency response is excellent as we would expect:
Channel separation is better than average:
Multitone just clears the hurdle for 16-bit content:
Distortion hardly increases at higher frequencies which means 19+20 KHz test also does well:
Company specs are easily met for power:
Max power was achieved at 1.7 volts so I ran my frequency vs power sweeps at that. While many amplifiers go into protection at high frequencies, the Vidar 2 blew its AC fuse. I replaced it with the spare that it came with and set the limit lower as to avoid clipping:
Given this, I didn’t try to pus the amp with my reactive load or testing it in mono. I trust their specs for the latter.
Conclusions
Nice to see Schiit improving on both usability and performance of the Vidar across the board. Company does a good job of staying competitive despite manufacturing products in US and giving 5 year warranty. I know many still find comfort in class AB designs and here you have a good example of it.
I am going to recommend the Schiit Vidar 2 amplifier.
