All of his suggestions can also easily be serviced if there is ever an issue
One idea could be a new Benchmark AHB2 + Benchmark DAC3 HGC - form factor would be same size as one integrated amp, and you hit both amplification and DAC in one go - fits your budget & simplifies your chain. I actually would be pretty curious about those

Good luck! Fun decision - let us know what you chose, when the new piece has arrived
