Muses03 on 1st try:
- Low end of OPA627 was thick after swap to Muses03 become more tight and firm with better impact exchange with smaller body compare to OPA627.
- Mid, there is no much different. What i notice is vocal abit lay back on MUSES03 while OPA627 more up front in vocal position.
- High, more crisp and clear on Muses03 but there is some harsh sound eg: "sh, zh" sound on vocal and small crash.
-Soundstage noticeably wider on Muses03 and layer separation is better and more precise. Muses03 better in dynamic as well.
-Overall Muses03 is less neutral compare to OPA627, It seem more live feel to me on Muses03
Muses03 after burn-in:
Sound character feel the same as 1st try. I love that tight and punchy impact. Vocal lay back that i mention on 1st try improve abit still not that up front as OPA627. Harsh sound on high get more smooth but still hear it some time(I try swap Dual AD797 to Muses01 it help alot of that harsh sound PL; Dual AD797 vs Muses01 review soon). Soundstage wide and clear. layer separation better than 1st try.
