I have those and many others. The Moondrop Kato is a big upgrade and I just get in a good mood whenever I switch to those. Source is key, FLAC 44.1khz 16 bit for the music collection. Also I just got a Tanchjim Space today and it's a nice upgrade over the Apple 3.5mm USB adapter I was using for travel. Both are absolutely solid value for the money. Also Aliexpress has that huge sale until the 27th if you want rock bottom prices. I just got a Topping A70Pro for $350 delivered with coins, coupons, and 3 percent cashback on a credit card, plus 2 year warranty since it's doubled. You can get great deals on IEM's and stuff too.
