tube amps for B & W 603's ???

just purchased the 603's which are brighter than the merlin 1B+ that I loved for many years using a B&K st140 and superphon revelation II that are now 19 years young. I was thinking of getting a VTL integrated but they won't return emails so I assume they are no longer in business? and if I did purchase a used VTL unit where in S.E. michigan would I have it repaired?

I have considered getting a conrad johnson preamp model 12L or comparable counterpoint model because of perceived customer support and updating the power amp next year come tax time. but the idea of the VTL integrated appeals to me more at this time because I would be covering both bases.

thanks to all who answer...mark
