The Monolith is more reliable than the Drop one. Bought my Drop one last holiday season and it broke after 3 months of use but that one was on me because I was running cans on the Balanced XLR using a 3.5mm to XLR adapter + daisy chaining one too many adapaters (Terrible Idea and such a noob mistake of me. You can get away with 3.5 to 2.5mm/4.4mm adapter, but NEVER with an XLR.) Nowadays, I stick to SE to SE and Balanced to Balanced to ensure proper load and longevity of the AMP. Drop amp eventually tripped the OCP and stop powered on ever since.
