I just got my S-A701 and replaced my FOSI V3 Mono's + Schiit Saga 2 and what can I say, even my mom said, wow this sounds alot better without knowing anything in reagrds to sound. It simply opened up, no need for heavy EQ in my WiiM Ultra now EQ is off and it sounds fantastic. Speakers are: Wharfedale EVO 5.4 - bonus is no need for all the extra wires and a more clean setup, it's impressive how good of an amp this is for 618 Eurs on Amazon. I also tryid to test the DACS i have, Yamaha build in, sounds fine too me, vs the built in in the WiiM Ultra plus my SMSL-SU1 and honestly again, they all sound great - hard to really pin-point. Now I'm wondering if i just stay put, or try one last upgrade going for lets say a Topping E70 Pro plus or E70 Velvet, but again I'm not sure i might hear any differance, and I'm not hear too hunt the last 5%. I need upgrades that can give minimum 25 % extra, like the Yamaha did, this was too me and insane differance in sound with my speakers, I'm still trying too understand how great it is, and how powerfull it is. This will give alot of joy, the next many years. The Fosi V3 is nice for what it is, but they are not going into my main system again, might end up in the kitchen too make egs on them as they are this hot. Yamaha is cool as ice compared
