In all fairness, the Moon i5.3 cannot be compared to the liquidity of the Cayin. The simaudio product sounds harsh and dry by comparison.
If you need a solid state amp to compete with the Cayin, I would recommend Electrocompaniet products, as they have a tube-like presentation. I have owned the above (Cayin, Electro and SIM) and virtually everyone who has listened to the Cayin gave it a best buy consideration against twice-the-price products.
