I understand how some having been exposed to cheap class D amps would react like they do. But, they failed find out about the excellent ones. I find that with a great class D amp in certain respects tubes will not be missed. There is one company that does not buy modules from Hypex nor ICE. They pioneered their own design and use them in their own amps. For an integrated amp? NuPrime makes several integrated amps. Links to reviews within the review.
