I've been enjoying my Topping G5 a lot, the most portable Amp for the power. Powerful enough to power my Susvaras. They took a while to ship from China and I forgot I had placed orders from two different places because one place was out of stock. So I have a second that just came in. Only opened to make sure everything was ok and not DOA. I'm not going to ship it back to China so offering for foks in the US wants a new one shipped from California, and avoid the multi-week shipping from China and no taxes. $275 shipped to you.
