Hi, i have H160. I did not have the H200 before but H160 is supposed to sound a little better.
However with H160 you loose some power compare to H200 and the ability to biwire, if that is a thing that you are interested in. The dac included in H160 is not bad but like most internal dacs, is easily outperformed by a half decent external dac (in my case NAD D1050).
So my answer to you is simple. If the reason you consider the upgrade is because you just want to get rid of the external dac and have an one box solution there is some merit in upgrading to H160.
However IMHO you will better upgrade your system by keeping your H200 and replace your Arcam with a better one, preferably with balanced outputs.
Jeg benytter for tiden Hegel H200 og Arcam Irdac med Buchardt Audio S300mk2 og det låter fantastisk,men...oppgraderingsspøkelset hvisker meg noe i øret....H160
Er det noen her som kjenner H200/Irdac og H160 og kan gi meg noen tips om jeg bør slå meg til ro med den komboen jeg har nå eller om jeg virkelig vil få nye eargasms med H160?
