my s530d setting now is SW+1,Bass+2,Treble+4 (Music)
+5, +4, +6 (Movie,blast song)

my experience, this speaker bass will getting stronger on same setting...time by time until it fully burn in....(probably 3xx~4xxhour),Initially my music setting also quite high...sw+4~+5...but now +1 feel balance edi...

treble part also getting smoother

overall ok, but nothing special of this speaker's performance~just balance with acceptable detail, cant request much from this price range product...

imo....i think wm8501 better than u1...while with s530d, but u1 provide higher output power to headphone/earphone....and wm8501 provide better mid range and smoother treble...slightly better bass

and according my fred whom owned u1 and xfi 5.1 usb told me if turn off all enhancement setting, then both of them performance are very close...but my fred prefer xfi 5.1 due it software enhancement....

s530/s730...suggest around 200 hours above to enter its good condition......

how about let its volume level fixed @ certain position then use OS volume control?

this issue like is popular problem that exist on s2.1d

personally only owned s330, and audit C3 and C2(similar version with HCS2330)

size: s330<c2<<c3 so if u have limited space u know how to choose

treble: c2<c3<s330

mid: c2<s330<c3 but if upper mid probably s330 better,it sound good with female vocal but lack of lower mid hence obvious gap with its subwoofer (quite often happened with pc 2.1 speaker)

bass: c2<s330<c3 ~personally prefer c3 bass over s330, due it go deeper to me, and s330 do offer more quantity in term of bass but not that deep.

c2 did not get my good impression, but i did not sure about is it sound similar with HCS2330

cons: since i only owned s330, volume not that enough for me since it sound start distort @ around 65% of its wired controller, bass go muddy around this volume also(bass setting around 1 o clock, and lack of lower mid(hence vocal thin), not punchy enough, but did not expect much from its price....

other brand recommendation, with your budget, can consider logitech z623 as well, different sound signature, since sound depend on personal preference, so you better go audit them and trust ur ear....
