I am thrilled with my Marantz Model 30 integrated amp. Stereophile has a nice review and is a "2021, 2022 Recommended Class A" ... Now my setup includes an A/B switch (One Little Bear) that allows me to select this Class D amp OR a Class A SET all tube Integrated AMP driving one pair of Cornwall speakers (it can actually drive 2 pairs of speakers). Best of both worlds ! Solid State AMPs are just so much more practical.
