What kind of speakers are you using? I've never heard the Unico, but have owned the Jolida 1501RC in the past. I think the Jolida is a fantastic amp. You might want to try auditioning one to see if it has better synergy with the rest of your system. Also, since it's a lot cheaper than the Unico, you could probably get some mods done to it as well. I know Response Audio (www.responseaudio.com) does some mods for Jolida products (I have no affiliation with them).
Good Luck,
