If it costs less and sounds wonderful to you, then I say stay with your approach.
The thinking behind the opposite position is that the digital-to-digital conversion (DDC) that takes place in a streamer is (electronically) noisy and is best done outside of the enclosure where digital-to-analog conversion takes place.
In an integrated amp, where multiple functions take place inside the single enclosure, adding one more function, i.e, DDC, into the mix may have a negligeable effect.
