Jford,
I am extremely pleased to see that you are using the Jamo's. I have the Jamo Concert 8 bookshelves and I just can't get myself to replace them. I've auditioned many other speakers by dynaudio and jm lab but haven't found any with in a reasonable price jump to purchase. I was thinking about trying tubes myself. I am using Naim equipment right now which has paired up extremely well with my speakers. When shopping around I will keep Cary in mind. It is always nice to find a company that will stand behind their products. Congratulations on your system and good luck with any future changes. Bill
