Guys, Quick question. Was offered a pair of Alectos MkII and Argo HR+Hera PSU. I currently have an MF A3.2 integrated. The question is: would this be a good investment given their age vs the quality of sound? Or would it be wiser to go for something like a NuVista M3 Integrated instead? (prices being more and less the same)? Or better to not go for any of them? Opinions, thoughts, all welcome! Thanks everybody! Jack
