Not sure if I am the lucky owner of this fine HiFi gear, I purchased the Yamaha A-28 receiver eons ago, (I think I paid $20 for it). I decided to hook up my HE400i to it and play through the Spodify Headphone test play list. I was blown away with the performance of this setup. I am using my Dell laptop connected to a Type C hub. and use the headphone out converted to RCA feeding this AMP. The Headphone out to the HiFiman 400i blew my mind. I own more expensive headphone., I find this setup is the best for the budget. I am not saying this will out perform $10,000 but for $20? I can live with it. (I was going to purchase the THX AAA 789 for $400). Once I hook up my rig. I have no desire to own the best out there. So if you are in a tight budget, give this a try. The Yamaha comes with a 7 band EQ and a Loudness adj. I am also powering my passive computer monitor (SONY) with it.
