Murataltuev,
Yes, Flow are night and day compared with the Echoles I had. Actually the Argento Serenity SE was much better than Echole.
I haven't tried the Odin but I can tell you that the Valhalla is a joke compared to the Organic Audio interconnect (by Argento) that costs around 600 Euros. There are a couple of people saying that the Organic is better than the Odin but if I don't hear it myself I cannot confirm anything.
