OP
I believe that you may have a winner there. and you claim that it sounds great. that is all good!
now, I was on that road before, but I kept on going on, listening to better gear.
as I listened to mega dollar audio gear at shows, I compared and realize what I am missing. and as you get accustomed to mega $$ gear, your ears and brain get trained to listen to nuances, sound staging and microdetails that are NOT present in cheaper gear. that has been MY personal journey and may be different from yours
so good luck, as I said, you may have a winner in your hands!!
just my 02 cents, but I am using a Fosi V3 with upgrade OP-Amps in my home theater. they sound great driving my Bowers and Wilkens 707,
