How good is Krell Phantom III?

I currently have the opportunity to purchase a Krell Phantom 3 . I just wonder how good it is because I don't see a lot of review for this product on the internet

My system consist of KEF reference 1, Mcintosh MC353, Chord Qutest DAC, all of my cables are from audioquest

Any opinion is welcome since I am new to this audiophile world

Thanks so much
