- Page 4 Thanks to ClieOS for detailed combination testing Rolling fun! on Head‐Fi review: http://www.head‐fi.org/products/asus‐xonar‐ essence‐stu/reviews/9307 I/V rolling (Stock LPF: LM4562) LM49720 Stock– well balanced, clean, airy and open but slightly to the warm side. LM49720 ‘Metal Can’– almost identical to stock, but just a tap fuller in body. OPA2604 – denser, not as airy and open as stock. OPA2209 – bass note is a little lean, good height. OP270 – Also dense, but a little better soundstage than OPA2604. OP275 – Leaner and brighter than stock, almost grainy. Good soundstage. AD8066 – Even brighter than OP275, but without the graininess. Slightly flat in soundstage but good width. OPA2227 – Forward, full and bright, slightly grainy. OPA2134 – More mid centric, lack soundstage. MUSES01 – Similar to Stock, with better dynamic and impressive soundstage. MUSES920 – full and forward, like smoother OPA2227. LPF rolling ( Stock I/V: LM49720) LM4562 – stock, again: well balanced, clean, airy and open but slightly to the warm side. LM49720 ‘Metal Can’ – Similar to stock, slightly less dense and more open in the mid. OPA2604 – thick and slow, grainy. OPA2209 – Full, similar to OPA2604 but without being overly thick and slow. OP270 – Lean, slightly lacking in bass, slightly bright.
