Mopmerantz my home office system is primarily used to fill in the background of a normally boring day working though I listen to it 6-7 hours a day 5 days a week it gets used far more then my main system, being married with kids I could never ever get away with that .
The dac I use Gustard A-26 chip base is much lower in price then your budget though it’s not a r2r it’s brother the Gustard R-26 is I understand this model also is equal with performance way beyond its retail price .
