I have the following integrated amp replacement stack from Schitt Audio in my office. It is my second best system.
Schiit Audio: Audio Products Made in USA
My DAC is the Schitt Yggi+ OG, but I would get the lower cost DAC offered in the Gigastack package since it is also very good. I also got the Kara F preamp and had the Freya+ previously. I like the Kara F more.
It is as good as the following gear I had previously (maybe a bit better and more features for sure)
- 8k amp, 9k amp, 7k preamp, 15k DAC and streamer, 8k integrated amp 7k integrated amp
The Wotan amp is one of the most powerful amps I have owned. It needed about 2 months of heavy play to sound as good as it does now.
You also get a 15-day home trial period to hear it before you commit. Though the amp and DAC will need more time to sound their best.
