I do not have a lot of experience with different racks. I have had Lovan (Classic), Salamander (Archetype) and Arcici (Suspense).
Arcici is far more expensive than the other two. It is also far superior. I hear more detail, clearer highs, more solid bass and lower soundfloor.
In my opinion the Arcici Suspense is worth the money, though I do not have experience with other higher quality racks and so cannot express a relative opinin of these others brands.
